BMJ Open: first published as 10.1136/bmjopen-2015-010387 on 4 April 2016. Downloaded from 1 2 3 ABSTRACT 4 5 6 7 Objective: To show the extent of the problem of falsified medicines in Peru. 8 9 10 Design: A retrospective review of drug alerts. 11 12 Setting: The General Directorate of Medicines, Supplies and Drugs (DIGEMID - 13 Ministry of Health of Peru) website search for drug alerts issued between 1997 14 and 2014. 15 For peer review only 16 Eligibility criteria: Drug alerts related to falsified medicines. 17 18 19 Results: A total of 669 Digemid Alerts were issued during the study period, 354 20 (52.91%) of which refer to a total of 1738 cases of falsified medicines (many 21 alerts deal with several cases at a time). Regarding the type of establishment 22 involved in the possession or sale of falsified medicines, 1010 cases (58.11%) 23 involved pharmaceutical establishments; 349 cases (20.08%) involved non- 24 pharmaceutical commercial outlets); in 126 cases (7.23%) the medicines were 25 seized in unauthorized trade (without any marketing authorization), and in 253 26 cases (14.56%) the type of establishment or business related with the seized 27 product is not identified. 28 29 30 The finding of 626 duplicate products/batches in the study period highlights the 31 persistence of falsified medicines on the market, and suggests that the impact 32 of the alert system needs to be revised.

33 http://bmjopen.bmj.com/ 34 Conclusions: In light of the results, there is no doubt that falsified medicines 35 represent a serious public health problem in Peru. A review of the data alone is 36 not enough to conclude whether falsified medicines in Peru have increased 37 38 during the study period, or if the monitoring action of different government 39 health agencies has brought the magnitude of the problem more to the surface 40 by providing more evidence. The problem is clearly structural, since the majority

41 of cases (58.11% of the total) were detected in legitimate supply chains. Most on September 24, 2021 by guest.

BMJ Open: first published as 10.1136/bmjopen-2015-010387 on 4 April 2016. Downloaded from 1 2 3 INTRODUCTION 4 5 The WHO has been receiving reports of falsified medicines since 1982. [1] The 6 phenomenon was first referred to as a problem at the WHO Conference of 7 Experts on the Rational Use of Drugs in Nairobi, Kenya, in 1985. Since then, 8 public awareness of falsified medicines has grown, [2] and it has become a 9 10 major public health issue, as reflected by government initiatives worldwide in 11 response to the problem. 12 13 The issue of falsified medicines is so complex that, for example, even today 14 different definitions are used, or a falsified medicine is confused with one of 15 poor qualityFor (substandard), peer a serious review mistake that hampersonly the exchange of 16 information between countries, and makes it difficult to grasp the true scale of a 17 global problem. The WHO defines falsified medicines as those whose labels 18 19 include, intentionally and fraudulently, false information about their identity and 20 origin. Falsification can affect both branded and generic products, and may 21 include products with the correct or wrong ingredients, without active [2] 22 ingredients, with insufficient active ingredients or with fake packaging. 23 24 According to the WHO, the highest rates of medicine falsification in the world 25 occur in regions with the weakest regulatory and control systems, such as many 26 African, Asian, and Latin American nations and countries in transition. In most 27 industrialized nations, regulatory systems and market control are effective and 28 29 thus the incidence of spurious/falsely-labeled/falsified/counterfeit medicines is low, estimated to be less than 1% of the market value. [3] Medicine falsification 30 [4] 31 involves manufacturing and distribution networks related to organized crime, [5-6] 32 with annual turnovers between 75 and 200 billion dollars and has a [7] 33 significant impact even in large economies like the US. http://bmjopen.bmj.com/ 34 35 In general, the deregulation of any trade or business and the existence of 36 uninformed potential customers constitute a breeding ground for unscrupulous 37 criminal activities, whose sole purpose is to obtain illegitimate profits at the 38 39 expense of harming consumers and, in this case, the health system. In short, 40 this is what has happened with medicines in Peru (according to the World Bank,

41 a country of upper-middle income with a gross national income per capita of $ on September 24, 2021 by guest. Protected copyright. [8] 42 4126 - 12,745). A staple product (medicine) was subjected to the free market 43 by a political decision in the early 1990s without the slightest preliminary 44 analysis of the possible consequences, which have proved disastrous. Attempts 45 to amend certain irregularities have not achieved convincing results so far, as 46 evidenced by this study, despite the efforts and resources invested over the last 47 few years. 48 49 50 The consequences of this illegal phenomenon represent a serious public health [9] 51 problem, including treatment failure, possible cases of added contaminants, 52 and even death. It has also resulted in the deployment and disbursement of 53 often scarce resources, a loss of faith in health systems, distrust of medications 54 and even the failure of major global health policies such as the fight against 55 malaria.

Downloaded from 1 2 3 The regulatory authority for medicines in Peru is the General Directorate of 4 Medicines, Supplies and Drugs (DIGEMID), created by the Legislative Decree 5 No. 584 of 16 April 1990, [11] as a linear agency of the Ministry of Health of Peru. 6 In May 1998, the work instigated by the Directorial Resolution No. 367-98-DG- 7 DIGEMID in 1997 was normalized, and the Alerts Committee was created to 8 evaluate and define the actions to take regarding alerts or communications 9 [12] 10 about safety and/or efficacy of pharmaceuticals and related products. 11 12 13 14 OBJECTIVE 15 For peer review only 16 This work seeks to consolidate and assess information on falsified medicines in 17 pharmaceutical alerts issued by the Peruvian medicine agency in a period of 18 18 19 years (1997-2014) of health monitoring and enforcement. The ultimate aim is to 20 draw attention to the situation of falsified medicines in Peru and highlight the 21 efforts of various state institutions headed by DIGEMID. 22 23 24 25 METHOD 26 27 To develop this work, a retrospective and systematic review was carried out of 28 each Digemid alert about falsified medicines, published on the official DIGEMID 29 [13] 30 website from 1997 to December 2014. 31 32 Data from each of the aforementioned Digemid alerts were collected and

33 organized in Microsoft Excel spreadsheets, considering, extracting, and filling in http://bmjopen.bmj.com/ 34 the following information: 35 36  Alerts ordered by year. 37 38  Title of the published Digemid alert. 39  Date of publication. 40  Medicine.

It should 27 be mentioned that there is no direct relationship between the number of 28 29 Digemid alerts and the number of falsified medicines, since several alerts refer 30 to more than one medicine or different batches of the same product. In this [14] 31 sense, Digemid alert no. 27 of 2012 particularly stands out, as it deals with 32 74 cases of falsified medicines. Thus, the 354 Digemid alerts concerning

33 falsified medicines include a total of 1738 reported cases (Figure 1 and 2). http://bmjopen.bmj.com/ 34 35 36 37 Figure 1. Flow diagram showing types of Digemid alerts and overall 38 39 results. 40

Regarding the 5 type of outlet/establishment involved in the possession or sale of falsified 6 7 medicines leading to the issue of a DIGEMID alert, 1010 cases (58.11%) of the 8 total involved pharmaceutical establishments (pharmaceutical offices, 9 droguerías, botiquines and laboratories); 349 (20.08%) involved non- 10 11 pharmaceutical establishments (non-pharmaceutical commercial outlets); in 126 12 cases (7.25%) falsified medicines were seized in unauthorized trade (without 13 any marketing authorization), including 10 cases of clandestine laboratories; 14 and finally in 253 (14.56%) cases there is insufficient information to clearly 15 For peer review only 16 identify the type of establishment or business involved. 17 18 Regarding the pharmaceutical establishments, it should be noted that 850 19 (84.16%) of all cases of falsified medicines involved boticas and 130 (12.87%) 20 21 involved pharmacies (Table 1). 22 23 Table 1.

BMJ Open: first published as 10.1136/bmjopen-2015-010387 on 4 April 2016. Downloaded from 1 2 3 Regarding the location where falsified medicines were seized, Lima province 4 had the highest number of cases with 582 (33.49%), far outstripping La 5 Libertad, which had 315 (18.12%). Interestingly, no cases were reported in the 6 7 departments of Huanuco and Tumbes. More details are shown in Figure 3. 8 9 10 Figure 3.

33 study period, since their decentralization coincided with an increase in http://bmjopen.bmj.com/ 34 inspections. This resulted in greater effectiveness, as can be seen in Figure 4. 35 36 Figure 4. Evolution of inspections according to the promoter. 37 38 39 40

BMJ Open: first published as 10.1136/bmjopen-2015-010387 on 4 April 2016. Downloaded from 1 2 3 Regarding the dosage form, 26 different types were found in the study period, 4 the most common being tablets (including coated and chewable), with a total of 5 816 cases (73.38%), followed by injectable dosage forms (injectable solution, 6 powder for injectable suspension, injectable suspension and powder for 7 injectable solution), with a total of 111 cases (9.98%); and 76 cases involving 8 capsules (6.83%). 9 10 11 Among the falsified medicines featured in the alerts of the study period, 164 12 cases (14.75%) had characteristics and/or information that did not correspond 13 to the product specifications, 100 (8.99%) did not contain an active ingredient, 14 12 (1.08%) had a different active ingredient to the one on the label, and 7 15 (0.63%) For had the correctpeer active ingredientreview but with only a different content than 16 authorized. It is noteworthy that in most cases 829 (74.55%) no information was 17 provided, which prevents a significant overall assessment. 18 19 20 21 22 DISCUSSION 23 24 Digemid alerts represent a valuable resource for the transfer of information on 25 the safety of medicines and related products to the general public. To be 26 effective and efficient, the alerts should provide detailed, homogenized and 27 standardized data. A timely assessment of their impact with respect to these 28 29 objectives is recommended. 30 31 This review demonstrates that the problem of falsified medicines in Peru is far 32 from insignificant. On the contrary, in light of the results presented here, the

33 country is facing a serious public health problem, which is even more apparent http://bmjopen.bmj.com/ 34 if these results are compared with those of similar studies in countries of high 35 health surveillance, such as the UK, with 7 cases of falsified medicines in 11 36 years (2001-2011) [15] or Canada with 4 cases in nine years (2005-2013). [16] 37 The difference is overwhelming. 38 39 40 One of the most striking and troubling aspects of the findings of this study is the

41 extent to which the medicine supply chain in Peru is being violated, with the on September 24, 2021 by guest. Protected copyright. 42 highest rate of falsified drugs found in pharmaceutical establishments 43 (pharmacies and boticas): 980 (56.39%) of a total of 1738 cases. This situation 44 is particularly worrying since, according to the Institute of Statistics and 45 Informatics of Peru (INEI), the Peruvian population mainly relies on the 46 pharmacy or botica for health care. [17] As well as a loss of consumer faith in the 47 legal supply chain, the resources, strategies and communication activities that 48 49 promote the responsible acquisition of safe medicines in legally established 50 pharmaceutical establishments are also being undermined. This situation 51 requires the active and joint participation of the regulatory authority and the 52 institutions representing the pharmaceutical establishments; moreover, the 53 cornerstone in solving the problem would be to grant a leading role to the 54 pharmaceutical professionals.

Downloaded from 1 2 3 No less worrying are the 349 cases involving non-pharmaceutical outlets, or the 4 126 cases of unauthorized trade, which include 10 cases related to clandestine 5 laboratories. 6 7 Considering the population of Lima (34.53% of Peru’s 30,475,144 8 inhabitants), [19] it is not surprising that the capital city is the location of 582 9 10 cases in the falsified medicine alerts (33.49%), followed by La Libertad with 315 11 cases (18.12%). As indicated by the WHO, there can be an enormous variation 12 in the incidence of falsified medicines within the same country, whether 13 between rural and urban areas or between different cities. [20] This is an 14 important factor for the planning of appropriate strategies to combat the 15 problem.For peer review only 16 17 In this study, it is especially interesting to note the effect of the decentralization 18 of public health surveillance powers. In 1999, the Ministerial Resolution No. 19 [21] 20 150-99 / DM decreed that the regional and sub-regional health directorates 21 assume the functions of health control and monitoring, although the rules of 22 procedure and operation were not approved until 2003 by the Ministerial 23 Resolution No. 573-2003-SA / DM. [22] After a period of implementation, the 24 results begin to be seen in 2005, when the regional directorates participated in 25 8 cases, which grew to 75 in 2006 and 128 in 2007, reaching a cumulative 1006 26 cases over the study period, representing 57.88% of the total. In parallel, the 27 operational role of the centralized body, DIGEMID, was reduced, replaced by 28 29 coordination functions, among others. 30 31 In the period covered by this review, the alerts alluded to 1112 cases of 32 counterfeit medicines (product/batch). Based on the pharmacological/ [23] 33 therapeutic subgroups (2nd level) of the ATC code allotted to registered http://bmjopen.bmj.com/ 34 products in the DIGEMID database, [24] the most falsified medicines in Peru 35 were Analgesics (251 – 22,57%), followed by Antibacterials for systemic use 36 (220 – 19.78%) and Other gynecologicals (178 – 16.01%), Antihistamines for 37 systemic use (68 – 6.12%), and Vitamins (65 – 5.85%). To some extent, these 38 results reflect the most consumed medicines in Peru, as reported in the 2008 39 [25] 40 study, "The therapeutic value of the best-selling medicines in Peru", which according to the IMS are likely to remain the same in the near future. [26] At this 41 on September 24, 2021 by guest. Protected copyright. 42 point, it is pertinent to raise the issue of implementation of modern technologies 43 to detect falsified medicines [27] and the development of tools for the traceability 44 of pharmaceutical products. Among these are radio frequency technology [28-34] 45 and two-dimensional codes such as the Datamatrix system. Modern analytical 46 methods have been adapted to identify counterfeit medicines, leading to faster 47 and more effective results and allowing more timely action and communication 48 by the health authorities. In this way, the alert system is not only informative, but 49 [35-43] 50 becomes an effective tool. 51 52 The liberalization of the world economy, with fewer commercial borders and a 53 growing impact of the Internet on medicine advertising and trade means that 54 proposals for measures need to be global. Although the Digemid alerts provide 55 no data on the issue, trade in falsified medicines over the Internet is a major 56 global problem (particularly in developed countries). [44-45] Mafias involved in 57 medicine falsification will not have overlooked that the global pharmaceutical 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 11 of 27 BMJ Open

[46] The concern about falsified medicine is growing worldwide, in 5 developed as well as developing countries; although quantitatively different, its 6 impact on public health and the economy is similar in both. 7 8 Continuing the work of inspection is vital. Due to the magnitude of the problem, 9 10 the measures, activities and behaviors that allow high levels of falsified 11 medicines to enter the Peruvian pharmaceutical market, with a worrying [47] 12 violation of the legal supply chain, require a thorough analysis at an internal 13 (country) and external (global) level (using criteria used by the working groups 14 of the Member States of the WHO to define medical products as substandard, 15 spurious,For falsely-labeled, peer falsified review or counterfeit). only [48] It is necessary to 16 understand why the situation persists, despite the corrective measures in place. 17 All aspects of the problem need to be addressed, from health to economic, [49] 18 legal, [50] technological, social and cultural, which could lead to a renewal of 19 [51-55] 20 viable, effective and efficient strategies to combat this scourge. 21 22 A review based only on the data of the alerts cannot provide a precise 23 conclusion about the extent to which falsified medicines have penetrated the 24 Peruvian pharmaceutical market, or their typology. Nevertheless, the results of 25 this study give an idea of the magnitude of the problem, and suggest that a 26 rethinking of strategies is required to effectively combat the trade in falsified 27 medicines in Peru. Moreover, it is important to recognize that the situation could 28 [56] 29 worsen, as is occurring in many African countries. 30 31 32

33 STRENGTHS AND LIMITATIONS OF THIS STUDY http://bmjopen.bmj.com/ 34 35  Digemid alerts are published systematically, are organized by date, and 36 are readily available on the DIGEMID open access website. 37  The information they provide is not entirely homogenous and 38 39 standardized which is a limitation for an overall analysis. 40  The Digemid alerts do not use a standardized definition of falsified

Protected copyright. 42  The possible health effects resulting from the use of falsified medicines 43 are not addressed or included in the alerts. 44  Graphical reports of counterfeit medicines, which are an illustrative and 45 informative tool, are only provided in 3 alerts (Digemid Alerts 17-2006, 46 35-2005 y 40-2005). 47 48 49 50 51 CONCLUSIONS 52 53 In light of the results, it is clear that the falsification of medicines in Peru is 54 currently a serious public health problem. 55 56 A review based only on the data provided by alerts cannot conclude whether 57 58 falsified medicines have increased in Peru within the study period, or if the 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 12 of 27

Downloaded from 1 2 3 action of different public health surveillance bodies has brought more evidence 4 to the surface about the magnitude of the problem. 5 6 The type of falsified medicines found in Peru is characteristic of developing 7 countries. 8 9 10 The problem is clearly structural or due to pharmaceutical policy, since the 11 highest incidence of cases of falsified medicines leading to DIGEMID alerts 12 involve legal supply chains. 13 14 Most cases of falsified medicines have been found in large cities. 15 For peer review only 16 The decentralization of health management has had a significant impact from 17 the inspection point of view. 18 19 20 Much work remains to be done to address this serious public health concern, 21 both in Peru and worldwide. 22 23 24 25 ACKNOWLEDGMENTS 26 27 We especially thank and dedicate this review to all people that day to day 28 29 fighting the scourge of counterfeit medicines in Peru. 30 31 32

BMJ Open: first published as 10.1136/bmjopen-2015-010387 on 4 April 2016. Downloaded from 1 2 3 ABSTRACT 4 5 Objective: To show the extent of the problem of falsified medicines in Peru. 6 7 Design: A retrospective review of drug alerts. 8 9 10 Setting: The General Directorate of Medicines, Supplies and Drugs (DIGEMID - 11 Ministry of Health of Peru) website search for drug alerts issued between 1997 12 and 2014. 13 14 Eligibility criteria: Drug alerts related to falsified medicines. 15 For peer review only 16 Results: A total of 669 Digemid Alerts were issued during the study period, 354 17 (52.91%) of which refer to a total of 1 738 cases of falsified medicines (many 18 19 alerts deal with several cases at a time). Regarding the type of establishment 20 involved in the possession or sale of falsified medicines, 1 010 cases (58.11%) 21 involved pharmaceutical establishments; 349 cases (20.08%) involved non- 22 pharmaceutical commercial outlets); in 126 cases (7.23%) the medicines were 23 seized in unauthorized trade (without any marketing authorization), and in 253 24 cases (14.56%) the type of establishment or business related with the seized 25 product is not identified. 26 27 Conclusions: In light of the results, there is no doubt that falsified medicines 28 29 represent a serious public health problem in Peru. A review of the data alone is 30 not enough to conclude whether falsified medicines in Peru have increased 31 during the study period, or if the monitoring action of different government 32 health agencies has brought the magnitude of the problem more to the surface

33 by providing more evidence. The problem is clearly structural, since the majority http://bmjopen.bmj.com/ 34 of cases (58.11% of the total) were detected in legitimate supply chains. Most 35 falsified medicines involve staple pharmaceutical products and common dosage 36 forms. 37 38 39 Considerable work remains to be done to control the serious problem of falsified 40 medicines in Peru.

Protected copyright. 42 43 44 STRENGTHS AND LIMITATIONS OF THIS STUDY 45 46  Digemid alerts are published systematically, are organized by date, and 47 48 are readily available on the DIGEMID open access website. 49  The information they provide is not entirely homogenous and 50 standardized which is a limitation for an overall analysis. 51  The Digemid alerts do not use a standardized definition of falsified 52 medicines, thereby hindering an overall evaluation of the results. 53  The possible health effects resulting from the use of falsified medicines 54 are not addressed or included in the alerts. 55  Graphical reports of counterfeit medicines, which are an illustrative and 56 informative tool, are only provided in 3 alerts (Digemid Alerts 17-2006, 57 58 35-2005 y 40-2005). 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 3 of 26 BMJ Open

BMJ Open: first published as 10.1136/bmjopen-2015-010387 on 4 April 2016. Downloaded from 1 2 3 INTRODUCTION 4 5 The WHO has been receiving reports of falsified medicines since 1982. [1] The 6 phenomenon was first referred to as a problem at the WHO Conference of 7 Experts on the Rational Use of Drugs in Nairobi, Kenya, in 1985. Since then, 8 public awareness of falsified medicines has grown, [2] and it has become a 9 10 major public health issue, as reflected by government initiatives worldwide in 11 response to the problem. 12 13 The issue of falsified medicines is so complex that, for example, even today 14 different definitions are used, or a falsified medicine is confused with one of 15 poor qualityFor (substandard), peer a serious review mistake that hampersonly the exchange of 16 information between countries, and makes it difficult to grasp the true scale of a 17 global problem. The WHO defines falsified medicines as those whose labels 18 19 include, intentionally and fraudulently, false information about their identity and 20 origin. Falsification can affect both branded and generic products, and may 21 include products with the correct or wrong ingredients, without active [2] 22 ingredients, with insufficient active ingredients or with fake packaging. 23 24 According to the WHO, the highest rates of medicine falsification in the world 25 occur in regions with the weakest regulatory and control systems, such as many 26 African, Asian, and Latin American nations and countries in transition. In most 27 industrialized nations, regulatory systems and market control are effective and 28 29 thus the incidence of spurious/falsely-labeled/falsified/counterfeit medicines is low, estimated to be less than 1% of the market value. [3] Medicine falsification 30 [4] 31 involves manufacturing and distribution networks related to organized crime, [5-6] 32 with annual turnovers between 75 and 200 billion dollars and has a [7] 33 significant impact even in large economies like the US. http://bmjopen.bmj.com/ 34 35 In general, the deregulation of any trade or business and the existence of 36 uninformed potential customers constitute a breeding ground for unscrupulous 37 criminal activities, whose sole purpose is to obtain illegitimate profits at the 38 39 expense of harming consumers and, in this case, the health system. In short, 40 this is what has happened with medicines in Peru (according to the World Bank,

41 a country of upper-middle income with a gross national income per capita of on September 24, 2021 by guest. Protected copyright. [8] 42 $ 4 126 – 12 745). 43 44 In Peru in the early 1990s, with the excuse of an economic crisis, the regulated 45 market for medicines was replaced by an open market, in line with the 46 neoliberal economic model of the moment. For example, ownership of the 47 community pharmacy was no longer the exclusive right of pharmacists, and 48 49 anyone with enough capital could open a pharmaceutical office, in any location, 50 and without rigorous prior control. This change was based on a political decision 51 without a preliminary analysis of the possible consequences, such as the 52 chaotic growth in the number of pharmaceutical establishments, which is 53 currently 23 527 [9] (259 in 1980 - 1989; 3 335 in 1990 – 1999 and 17 071 in 54 2000 - 2008) [10], rendering effective control by the authorities impossible. This 55 is arguably one of the main causes of the high number of cases of counterfeit 56 medicines found in the legal supply chain today. Attempts to resolve this 57 problem include Law No 26842 of 2009, which stipulates mandatory sanitary 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 4 of 26

[12] 7 8 The consequences of this illegal phenomenon represent a serious public health 9 [13] 10 problem, including treatment failure, possible cases of added contaminants, 11 and even death. It has also resulted in the deployment and disbursement of 12 often scarce resources, a loss of faith in health systems, distrust of medications 13 and even the failure of major global health policies such as the fight against 14 malaria. [14] 15 For peer review only 16 The regulatory authority for medicines in Peru is the General Directorate of 17 Medicines, Supplies and Drugs (DIGEMID), created by the Legislative Decree 18 [15] 19 No. 584 of 16 April 1990, as a dependent institution of the Ministry of Health 20 of Peru. In May 1998, the Directorial Resolution No. 367-98-DG-DIGEMID 21 established the Alerts Committee to evaluate and define the actions to take in 22 response to alerts or communications about safety and/or efficacy of 23 pharmaceuticals and related products. [16] 24 25 Inspectors of DIGEMID and regional health institutions carry out inspections 26 and spot checks of pharmaceutical products (in pharmaceutical and non- 27 pharmaceutical establishments), and also receive counterfeit drugs seized by 28 29 other regulatory authorities (National Police, Customs, etc.). Any suspected 30 deficiency or observable abnormality in a product leads to its seizure, and its 31 authenticity is then verified with the holder of the relevant marketing 32 authorization. If the suspected counterfeiting is confirmed, samples are

33 transferred to an Official Control Laboratory to complete the relevant physical- http://bmjopen.bmj.com/ 34 chemical and microbiological analyses. All the documentation and case history 35 is referred to the DIGEMID-Alerts Committee to approve the publication of the 36 corresponding alert in the institutional web page and to initiate internal and 37 external dissemination.

Downloaded from 1 2 3 Regarding the dosage form, 26 different types were found in the study period, 4 the most common being tablets (including coated and chewable), with a total of 5 816 cases (73.38%), followed by injectable dosage forms (injectable solution, 6 powder for injectable suspension, injectable suspension and powder for 7 injectable solution), with a total of 111 cases (9.98%); and 76 cases involving 8 capsules (6.83%). 9 10 11 Among the falsified medicines featured in the alerts of the study period, 164 12 cases (14.75%) had characteristics and/or information that did not correspond 13 to the product specifications, 100 (8.99%) did not contain an active ingredient, 14 12 (1.08%) had a different active ingredient to the one on the label, and 7 15 (0.63%) hadFor the correct peer active ingredient review but not the authorizedonly content of the 16 active ingredient. It is noteworthy that in most cases 829 (74.55%) no 17 information was provided, which prevents a significant overall assessment. 18 19 20 21 22 DISCUSSION 23 24 Digemid alerts represent a valuable resource for the transfer of information on 25 the safety of medicines and related products to the general public. To be 26 effective and efficient, the alerts should provide detailed, homogenized and 27 standardized data. It is worthwhile to make a timely assessment of their impact 28 29 on the goals of controlling and minimizing the risks associated with the trade 30 and use of counterfeit medicines. 31 32 This review demonstrates that the problem of falsified medicines in Peru is far

33 from insignificant. On the contrary, in light of the results presented here, the http://bmjopen.bmj.com/ 34 country is facing a serious public health problem, which is even more apparent 35 if these results are compared with those of similar studies in some countries 36 that are considered in Peru to have a high level of health surveillance, [23] such 37 as the UK, with 7 cases of falsified medicines in 11 years (2001-2011) [24] or 38 [25] 39 Canada with 4 cases in nine years (2005-2013). The difference is 40 overwhelming.

41 on September 24, 2021 by guest. Protected copyright. 42 One of the most striking and troubling aspects of the findings of this study is the 43 extent to which the medicine supply chain in Peru is being violated, with the 44 highest rate of falsified drugs found in pharmaceutical establishments 45 (pharmacies and boticas): 980 (56.39%) of a total of 1 738 cases. This situation 46 is particularly worrying since, according to the Institute of Statistics and 47 Informatics of Peru (INEI), the Peruvian population mainly relies on the 48 [26] 49 pharmacy or botica for health care. As well as a loss of consumer faith in the 50 legal supply chain, the resources, strategies and communication activities that 51 promote the responsible acquisition of safe medicines in legally established 52 pharmaceutical establishments are also being undermined. This situation 53 requires the active and joint participation of the regulatory authority and the 54 institutions representing the pharmaceutical establishments; moreover, the 55 cornerstone in solving the problem would be to grant a leading role to the 56 pharmacist, who should procure medicines from recognized and reliable 57 sources; warn patients against acquiring medicines from informal 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 13 of 26 BMJ Open

Downloaded from 1 2 3 establishments or places (including the internet); confirm that the distributors 4 buy products from approved suppliers; check the alerts on counterfeit medicines 5 issued by the health authority; be alert to products with suspicious features; 6 collaborate with the pharmaceutical industry, distributors and the health 7 authority to establish safety procedures that do not allow violation of the legal 8 supply chain; make use of available technology for the safe management and 9 10 traceability of medicines; receive training and trigger a process of updating 11 safety in the workplace, and report any suspicious activity or product to the [27] 12 health authority. 13 14 No less worrying are the 349 cases involving non-pharmaceutical outlets, or the 15 126 casesFor of unauthorized peer trade, whichreview include 10 cases only related to clandestine 16 laboratories. 17 18 Considering the population density of Lima (31.57% of Peru’s 31 151 643 19 [22] 20 inhabitants), it is not surprising that the capital city is the location of 562 21 cases in the falsified medicine alerts (32.34%), followed by La Libertad with 315 22 cases (18.12%). As indicated by the WHO, there can be an enormous variation 23 in the incidence of falsified medicines within the same country, whether 24 between rural and urban areas or between different cities. [28] This is an 25 important factor for the planning of appropriate strategies to combat the 26 problem. 27 28 29 In this study, it is especially interesting to note the effect of the decentralization of public health surveillance powers. In 1999, the Ministerial Resolution No. 30 [29] 31 150-99 / DM decreed that the regional and sub-regional health directorates 32 assume the functions of health control and monitoring, although the rules of

33 procedure and operation were not approved until 2003 by the Ministerial http://bmjopen.bmj.com/ 34 Resolution No. 573-2003-SA / DM. [30] After a period of implementation, the 35 results begin to be seen in 2005, when the regional directorates participated in 36 8 cases, which grew to 75 in 2006 and 128 in 2007, reaching a cumulative 37 1 006 cases over the study period, representing 57.88% of the total. In parallel, 38 39 the operational role of the centralized body, DIGEMID, was reduced, replaced 40 by coordination functions, among others.

41 on September 24, 2021 by guest. Protected copyright. 42 In the period covered by this review, the alerts alluded to 1 112 cases of 43 counterfeit medicines (product/batch). Based on the pharmacological/ 44 therapeutic subgroups (2nd level) of the ATC code [19] allotted to registered 45 products in the DIGEMID database, [20] the most falsified medicines in Peru 46 were Analgesics (251 – 22,57%), followed by Antibacterials for systemic use 47 (220 – 19.78%) and Other gynecologicals (178 – 16.01%), Antihistamines for 48 49 systemic use (68 – 6.12%), and Vitamins (65 – 5.85%). To some extent, these 50 results reflect the most consumed medicines in Peru, as reported in the 2008 [31] 51 study, "The therapeutic value of the best-selling medicines in Peru", which [32] 52 according to the IMS are likely to remain the same in the near future. At this 53 point, it is recommendable to raise the issue of implementation of modern 54 technologies to detect falsified medicines [33] and the development of tools for 55 the traceability of pharmaceutical products. Among these are radio frequency 56 technology [34-40] and two-dimensional codes such as the Datamatrix system. 57 Modern analytical methods have been adapted to identify counterfeit medicines, 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 14 of 26

Downloaded from 1 2 3 leading to faster and more effective results and allowing more timely action and 4 communication by the health authorities. In this way, the alert system is not only 5 informative, but becomes an effective tool. [41-49] 6 7 The liberalization of the world economy, with fewer commercial borders and a 8 growing impact of the Internet on medicine advertising and trade means that 9 10 proposals for measures need to be global, for example, an internationally 11 accepted standard terminology that allows better information management, 12 transparency and identification of brokers and commercial intermediaries, 13 legislative and regulatory harmonization, the implementation of traceability 14 systems, etc. Although the Digemid alerts provide no data on the issue, trade in 15 falsified medicinesFor overpeer the Internet review is a major global only problem (particularly in 16 developed countries).[50-51] Mafias involved in medicine falsification will not have 17 overlooked that the global pharmaceutical market is forecast to grow by around 18 4% per year (21% between 2012 and 2017).[52] The concern about falsified 19 20 medicine is growing worldwide, in developed as well as developing countries; 21 although quantitatively different, its impact on public health and the economy is 22 similar in both. 23 24 Continuing the work of inspection is vital. The magnitude and nature of the 25 problem require a thorough analysis at two levels: within the region or country 26 as well as globally. It is necessary to evaluate the measures, activities and 27 behaviours (WHO guidelines) [53] responsible for the high levels of counterfeit 28 medicines in the Peruvian pharmaceutical market, with an obvious and worrying 29 [54] 30 violation of the legal supply chain. It is necessary to understand why the 31 situation persists, despite the corrective measures in place. All aspects of the [55] [56] 32 problem need to be addressed, from health to economic, legal,

33 technological, social and cultural, which could lead to a renewal of viable, http://bmjopen.bmj.com/ 34 effective and efficient strategies [57-61] to combat this scourge. 35 36 The finding of 626 duplicate products/batches in the study period highlights the 37 persistence of falsified medicines on the market, and suggests that the impact 38 39 of the alert system needs to be revised. 40

41 A review based only on the data of the alerts cannot provide a precise on September 24, 2021 by guest.

Nevertheless, the results of 44 this study give an idea of the magnitude of the problem, and suggest that a 45 rethinking of strategies is required to effectively combat the trade in falsified 46 medicines in Peru. Moreover, it is important to recognize that the situation could 47 worsen, as is occurring in many African countries. [62] 48 49 50 51 52 CONCLUSIONS 53 54 In light of the results, it is clear that the falsification of medicines in Peru is 55 currently a serious public health problem.

The type of falsified medicines found in Peru is 5 characteristic of developing countries. The problem is clearly structural or due to 6 pharmaceutical policy, since the highest incidence of cases of falsified 7 medicines leading to DIGEMID alerts involve legal supply chains. Most cases of 8 falsified medicines have been found in large cities. The decentralization of 9 10 health management has had a significant impact from the inspection point of 11 view. It is necessary to establish systems of analysis and risk management 12 related to the counterfeit medicine trade as part of a regional, national and 13 global plan, in which pharmaceutical alerts form part of the communication 14 process and whose impact should be evaluated.

BMJ Open: first published as 10.1136/bmjopen-2015-010387 on 4 April 2016. Downloaded from 1 2 3 ABSTRACT 4 5 Objective: Consolidate and assess information on falsified medicines in 6 pharmaceutical alerts issued by the Peruvian Medicines Regulatory Authority in 7 a period of 18 years (1997-2014) of health monitoring and enforcement. 8 9 10 Design: A retrospective review of drug alerts. 11 12 Setting: The General Directorate of Medicines, Supplies and Drugs (DIGEMID - 13 Ministry of Health of Peru) website search for drug alerts issued between 1997 14 and 2014. 15 For peer review only 16 Eligibility criteria: Drug alerts related to falsified medicines. 17 18 19 Results: A total of 669 DIGEMID Alerts were issued during the study period, 20 354 (52.91%) of which refer to a total of 1 738 cases of falsified medicines 21 (many alerts deal with several cases at a time). Regarding the type of 22 establishment involved in the possession or sale of falsified medicines, 1 010 23 cases (58.11%) were pharmaceutical establishments; 349 cases (20.08%) were 24 non-pharmaceutical commercial outlets; in 126 cases (7.23%) the medicines 25 were seized in unauthorized trade (without any marketing authorization), and in 26 253 cases (14.56%) the type of establishment or business related with the 27 seized product is not identified. 28 29 30 Conclusions: In light of the results, there is no doubt that falsified medicines 31 represent a serious public health problem in Peru. A review of the data alone is 32 not enough to conclude whether falsified medicines in Peru have increased

33 during the study period, or if the monitoring action of different government http://bmjopen.bmj.com/ 34 health agencies has brought the magnitude of the problem more to the surface 35 by providing more evidence. The problem is clearly structural, since the majority 36 of cases (58.11% of the total) were detected in legitimate supply chains. Most 37 falsified medicines involve staple pharmaceutical products and common dosage 38 39 forms. 40

BMJ Open: first published as 10.1136/bmjopen-2015-010387 on 4 April 2016. Downloaded from 1 2 3 INTRODUCTION 4 5 The WHO has been receiving reports of falsified medicines since 1982. [1] The 6 phenomenon was first referred to as a problem at the WHO Conference of 7 Experts on the Rational Use of Drugs in Nairobi, Kenya, in 1985. Since then, 8 public awareness of falsified medicines has grown, [2] and it has become a 9 10 major public health issue, as reflected by government initiatives worldwide in 11 response to the problem. 12 13 The issue of falsified medicines is so complex that, for example, even today 14 different definitions are used, or a falsified medicine is confused with one of 15 poor qualityFor (substandard), peer a serious review mistake that hampersonly the exchange of 16 information between countries, and makes it difficult to grasp the true scale of a 17 global problem. The WHO defines falsified medicines as those whose labels 18 19 include, intentionally and fraudulently, false information about their identity and 20 origin. Falsification can affect both branded and generic products, and may 21 include products with the correct or wrong ingredients, without active [2] 22 ingredients, with insufficient active ingredients or with fake packaging. 23 24 According to the WHO, the highest rates of medicine falsification in the world 25 occur in regions with the weakest regulatory and control systems, such as many 26 African, Asian, and Latin American nations and countries in transition. In most 27 industrialized nations, regulatory systems and market control are effective and 28 29 thus the incidence of spurious/falsely-labelled/falsified/counterfeit medicines is low, estimated to be less than 1% of the market value. [3] Medicine falsification 30 [4] 31 involves manufacturing and distribution networks related to organized crime, [5-6] 32 with annual turnovers between 75 and 200 billion dollars and has a [7] 33 significant impact even in large economies like the US. http://bmjopen.bmj.com/ 34 35 In general, the deregulation of any trade or business and the existence of 36 uninformed consumers facilitate criminal activities of unscrupulous people, 37 whose sole purpose is to obtain illegitimate profits, at the expense of harming 38 39 consumers and the health system. This is the case of the medicine market in 40 Peru (according to the World Bank, a country of upper-middle income with a [8]

41 gross national income per capita of $ 4 126 – 12 745). on September 24, 2021 by guest. Protected copyright. 42 43 In Peru, in the early 1990s, with the excuse of an economic crisis, the regulated 44 market for medicines was replaced by an open market, in line with the 45 neoliberal economic model of the moment. For example, ownership of the 46 community pharmacy was no longer the exclusive right of pharmacists, and 47 anyone with enough capital could open a pharmaceutical office (store 48 49 dispensing and retailing pharmaceuticals and related products; with the same 50 function, can be pharmacies, where the owner is a pharmacist; or boticas, 51 where the owner is not a pharmacist), in any location, and without rigorous prior 52 control. This change was based on a political decision without a preliminary 53 analysis of the possible consequences, such as the chaotic growth in the 54 number of pharmaceutical establishments, which is currently 23 527 [9] (259 in 55 1980 - 1989; 3 335 in 1990 – 1999 and 17 071 in 2000 - 2008) [10], rendering 56 effective control by the authorities impossible. This is arguably one of the main 57 causes of the high number of cases of counterfeit medicines found in the legal 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 4 of 28

Attempts to resolve this problem include Law No 26842 of 4 2009, which stipulates mandatory sanitary authorization for the operation of 5 pharmaceutical establishments, with prior verification of compliance, [11] and 6 more recently a process of registration or special registration under the 7 Temporary Supplementary Provisions of the Supreme Decree No. 033-2014- 8 SA. [12] 9 10 11 The consequences of this illegal phenomenon represent a serious public health [13] 12 problem, including treatment failure, possible cases of added contaminants, 13 and even death. It has also resulted in the deployment and disbursement of 14 often scarce resources, a loss of faith in health systems, distrust of medications 15 and evenFor the failure peer of major global review health policies suchonly as the fight against 16 malaria. [14] 17 18 19 The regulatory authority for medicines in Peru is the General Directorate of Medicines, Supplies and Drugs (DIGEMID), created by the Legislative Decree 20 [15] 21 No. 584 of 16 April 1990, as a dependent institution of the Ministry of Health 22 of Peru. In May 1998, the Alerts Committee was established by the Directorial 23 Resolution No. 367-98-DG-DIGEMID to evaluate and define which actions 24 should be taken in response to alerts or communications about safety and/or 25 efficacy of pharmaceuticals and related products. [16] 26 27 Inspectors of DIGEMID and regional health institutions carry out inspections 28 29 and spot checks of pharmaceutical products (in pharmaceutical and non- 30 pharmaceutical establishments), and also receive counterfeit drugs seized by 31 other regulatory authorities (National Police, Customs, etc.). Any suspected 32 deficiency or observable abnormality in a product leads to its seizure, and its

33 authenticity is then verified with the holder of the relevant marketing http://bmjopen.bmj.com/ 34 authorization. If the suspected counterfeiting is confirmed, samples are 35 transferred to an Official Control Laboratory to complete the relevant physical- 36 chemical and microbiological analyses. All the documentation and case history 37 is referred to the DIGEMID-Alerts Committee to approve the publication of the 38 corresponding alert in the institutional web page and to initiate internal and 39 [17] 40 external dissemination.

Downloaded from 1 2 3 A falsified medicine is a product improperly manufactured, in a deliberate and 4 fraudulent manner with respect to its identity or its origin. They may include 5 products with right ingredients or with wrong ingredients, without active 6 pharmaceutical ingredients (APIs), with insufficient or wrong active 7 pharmaceutical ingredients (APIs) or with packaging or labelling falsified. [18] 8 9 10 A DIGEMID Alert is a document issued by the National Authority of 11 Pharmaceutical Products and Medical Devices, as a measure of health safety, 12 through which the regulatory actions and other actions, on the safety, 13 falsification, critical quality results, among others, related to pharmaceutical 14 products and medical devices are made known to the national scientific 15 communityFor and to thepeer public in general, review with the ultimate only objective of controlling 16 and minimising the risk related to the commercialisation and its respective use. 17 [17] 18 19 20 To be eligible for inclusion in the retrospective review, DIGEMID-alerts had to 21 include falsified medicines. The resulting DIGEMID alerts were compiled and 22 exclusion criteria included the following: medical devices, herbal products and 23 cosmetic products have been excluded, as have been cases related to quality, 24 general safety or regulation (for example, products without sanitary registration). 25 26 Data sources and searches 27 28 29 A search for DIGEMID-alerts related to falsified medicines products was carried 30 out. This was performed through the official DIGEMID website using the section 31 allocated for DIGEMID-alerts. [19] The first DIGEMID-alert published on the 32 DIGEMID website was in the year 1997; thus, all drug alerts issued between 33 1997 and 2014 were included. http://bmjopen.bmj.com/ 34 35 Data collection 36 37 38 All available DIGEMID alerts were reviewed, to make a final choice and to 39 determine their inclusion in the review. A structured Excel spreadsheet was 40 used to record relevant information and ensure uniformity of evaluation for each

The first level classifies medicine according to the system or organ 20 on which it acts; the second level classifies medicine according to its 21 therapeutic subgroup and the third level classifies medicine according to its [20] 22 pharmacological subgroup. The stated dosage form is in accordance with 23 the DIGEMID alerts or the database of the registration of pharmaceutical 24 products of the regulatory authority of medicinal products of Peru (PERUDIS). 25 [21] This was performed to highlight the most frequent therapeutic classes and 26 dosage forms affected by counterfeit drugs. The type of counterfeiting is 27 classified according to the assessment provided by the alerts: features and/or 28 29 information that do not match the product specifications, containing no active 30 ingredient, containing an active ingredient other than stated on the label, or 31 containing the correct active ingredient but not the authorised content. To be 32 more precise in the analysis of the type of counterfeit medicine, those with a

33 batch number subject of a previous alert are not taken into account. http://bmjopen.bmj.com/ 34 35 The result of the assessment of each one of the falsified medicinal products can 36 be divided into four groups: do not contain any active ingredient, contain active 37 ingredients other that those stated on the label, contain the active ingredient but 38 39 in in different dosage to the label claim or the result of the assessment does not 40 exist.

33 the safety of medicines and related products to the general public. To be http://bmjopen.bmj.com/ 34 effective and efficient, the alerts should provide detailed, homogenized and 35 standardized data. It is worthwhile to make a timely assessment of their impact 36 on the goals of controlling and minimizing the risks associated with the trade 37 and use of counterfeit medicines. 38 39 This review demonstrates that the problem of falsified medicines in Peru is far 40 from insignificant. On the contrary, in light of the results presented here, the

41 on September 24, 2021 by guest. Protected copyright. 42 country is facing a serious public health problem, which is even more apparent 43 if these results are compared with those of similar studies in some countries [24] 44 that are considered in Peru to have a high level of health surveillance, such 45 as the UK, with seven cases of falsified medicines in 11 years (2001-2011) [25] 46 or Canada with four cases in nine years (2005-2013); [26] reveals an 47 overwhelming difference. 48 49 One of the most striking and troubling aspects of the findings of this study is the 50 51 extent to which the medicine supply chain in Peru is being violated, with the 52 highest rate of falsified drugs found in pharmaceutical establishments 53 (pharmacies and boticas): 980 (56.39%) of a total of 1 738 cases. This situation 54 is particularly worrying since, according to the Institute of Statistics and 55 Informatics of Peru (INEI), the Peruvian population mainly relies on the 56 pharmacy or botica for health care. [27] As well as a loss of consumer faith in the 57 legal supply chain, the resources, strategies and communication activities that 58 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 14 of 28

Downloaded from 1 2 3 promote the responsible acquisition of safe medicines in legally established 4 pharmaceutical establishments are also being undermined. This situation 5 requires the active and joint participation of the regulatory authority and the 6 institutions representing the pharmaceutical establishments. Moreover, the 7 cornerstone in solving the problem would be to grant a leading role to the 8 pharmacist, who should procure medicines from recognized and reliable 9 10 sources; warn patients against acquiring medicines from informal 11 establishments or places (including the internet); confirm that the distributors 12 buy products from approved suppliers; check the alerts on counterfeit medicines 13 issued by the health authority; be alert to products with suspicious features; 14 collaborate with the pharmaceutical industry, distributors and the health 15 authority Forto establish peer safety procedures review that do not allowonly violation of the legal 16 supply chain; make use of available technology for the safe management and 17 traceability of medicines; receive training and trigger a process of updating 18 safety in the workplace, and report any suspicious activity or product to the 19 [28] 20 health authority. The pharmacists must be prepared to succeed in 21 confronting the challenge of the falsified medicines. 22 23 No less worrying are the 349 cases involving non-pharmaceutical outlets, or the 24 126 cases of unauthorized trade, which include 10 cases related to clandestine 25 laboratories. 26 27 Considering the population density of Lima (31.57% of Peru’s 31 151 643 28 [23] 29 inhabitants), it is not surprising that the capital city is the location of 562 30 cases in the falsified medicine alerts (32.34%), followed by La Libertad with 315 31 cases (18.12%). As indicated by the WHO, there can be an enormous variation 32 in the incidence of falsified medicines within the same country, whether [29] 33 between rural and urban areas or between different cities. This is an http://bmjopen.bmj.com/ 34 important factor for the planning of appropriate strategies to combat the 35 problem. 36 37 In this study, it is especially interesting to note the effect of the decentralization 38 of public health surveillance powers. In 1999, the Ministerial Resolution No. 39 [30] 40 150-99 / DM decreed that the regional and sub-regional health directorates assume the functions of health control and monitoring, although the rules of 41 on September 24, 2021 by guest. Protected copyright. 42 procedure and operation were not approved until the Ministerial Resolution No. 43 573-2003-SA / DM of 2003. [31] After a period of implementation, the results 44 began to be seen in 2005, when the regional directorates participated in 8 45 cases, which grew to 75 in 2006 and 128 in 2007, reaching a cumulative 1 006 46 cases over the study period, representing 57.88% of the total. In parallel, the 47 operational role of the centralized body, DIGEMID, was reduced, as it 48 49 concentrated more on coordination, among other functions. 50 51 In the period covered by this review, the alerts alluded to 1 112 cases of 52 counterfeit medicines (product/batch). Based on the pharmacological/ 53 therapeutic subgroups (2nd level) of the ATC code [20] allotted to registered 54 products in the DIGEMID database, [21] the most falsified medicines in Peru 55 were analgesics (251 – 22,57%), followed by antibacterials for systemic use 56 (220 – 19.78%) and other gynecologicals (178 – 16.01%), antihistamines for 57 systemic use (68 – 6.12%), and vitamins (65 – 5.85%).

BMJ Open: first published as 10.1136/bmjopen-2015-010387 on 4 April 2016. Downloaded from 1 2 3 results reflect the most consumed medicines in Peru, as reported in the 2008 4 study, "The therapeutic value of the best-selling medicines in Peru", [32] which 5 according to the IMS are likely to remain the same in the near future.[33] At this 6 point, it is recommendable to raise the issue of implementation of modern 7 technologies to detect falsified medicines [34] and the development of tools for 8 the traceability of pharmaceutical products. Among these are radio frequency 9 [35-41] 10 technology and two-dimensional codes such as the Datamatrix system. 11 Modern analytical methods have been adapted to identify counterfeit medicines, 12 leading to faster and more effective results and allowing more timely action and 13 communication by the health authorities. In this way, the alert system is not only 14 informative, but becomes an effective tool. [42-50] 15 For peer review only 16 The liberalization of the world economy, with fewer commercial borders and a 17 growing impact of the Internet on medicine advertising and trade means that 18 proposals for measures against falsified medicines need to be global. Solutions 19 20 include an internationally accepted standard terminology for improved 21 information management, transparency and identification of brokers and 22 commercial intermediaries, legislative and regulatory harmonization, the 23 implementation of traceability systems, etc. Although the DIGEMID alerts 24 provide no data on the issue, trade in falsified medicines over the Internet is a 25 major global problem (particularly in developed countries). [51-52] Mafias involved 26 in medicine falsification will not have overlooked that the global pharmaceutical 27 market is forecast to grow by around 4% per year (21% between 2012 and 28 2017). [53] The concern about falsified medicine is growing worldwide, in 29 30 developed as well as developing countries; although quantitatively different, its 31 impact on public health and the economy is similar in both. 32

33 Continuing the work of inspection is vital. The magnitude and nature of the http://bmjopen.bmj.com/ 34 problem require a thorough analysis at two levels: within the region or country 35 as well as globally. It is necessary to evaluate the measures, activities and 36 behaviours (WHO guidelines) [54] responsible for the high levels of counterfeit 37 medicines in the Peruvian pharmaceutical market, with an obvious and worrying 38 [55] 39 violation of the legal supply chain. It is necessary to understand why the 40 situation persists, despite the corrective measures in place. All aspects of the problem need to be addressed, from health to economic, [56] legal, [57] 41 on September 24, 2021 by guest. Protected copyright. 42 technological, social and cultural, which could lead to a renewal of viable, 43 effective and efficient strategies to combat this scourge. [58-62] 44 45 The finding of 626 duplicate products/batches in the study period highlights the 46 persistence of falsified medicines on the market, and suggests that the impact 47 of the alert system needs to be revised. 48 49 50 A review based only on the data of the alerts cannot provide a precise 51 conclusion about the extent to which falsified medicines have penetrated the 52 Peruvian pharmaceutical market, or their typology. Nevertheless, the results of 53 this study give an idea of the magnitude of the problem, and suggest that a 54 rethinking of strategies is required to effectively combat the trade in falsified 55 medicines in Peru. Moreover, it is important to recognize that the situation could 56 worsen, as is occurring in many African countries.

BMJ Open: first published as 10.1136/bmjopen-2015-010387 on 4 April 2016. Downloaded from 1 2 3 4 5 CONCLUSIONS 6 7 In light of the results, it is clear that the falsification of medicines in Peru is 8 currently a serious public health problem. A review based only on the data 9 10 provided by alerts cannot conclude whether falsified medicines have increased 11 in Peru within the study period, or if the action of different public health 12 surveillance bodies has brought more evidence to the surface about the 13 magnitude of the problem. The type of falsified medicines found in Peru is 14 characteristic of developing countries. The problem is clearly structural or due to 15 pharmaceuticalFor policy, peer since the review highest incidence only of cases of falsified 16 medicines leading to DIGEMID alerts involve legal supply chains. Most cases of 17 falsified medicines have been found in large cities. The decentralization of 18 19 health management has had a significant impact from the inspection point of 20 view. It is necessary to establish systems of analysis and risk management 21 related to the counterfeit medicine trade as part of a regional, national and 22 global plan, in which pharmaceutical alerts form part of the communication 23 process and whose impact should be evaluated. Much work remains to be done 24 to address this serious public health concern, both in Peru and worldwide. 25 26 27 28 29 ACKNOWLEDGMENTS 30 31 We especially thank and dedicate this review to all those who day to day are 32 fighting the scourge of counterfeit medicines in Peru.
