This has led a group of regulators to launch the International Generic Drug Regulators Pilot (IGDRP), aimed at regulatory convergence and cooperation. The three-year pilot entails a series of concrete measures to facilitate the timely authorization and availability of safe, effective and quality generic medicines. Results of the pilot will inform decisions on establishing a more permanent information and work-sharing arrangement as part of broader international efforts related to regulation of medicines. The success of the initiative will require the support of industry as well as other stakeholders interested in promoting access to affordable, quality generic medicines. Introduction regions become aligned over time as the The availability of quality generic drugs, same harmonized technical guidance also known as multi-source medicines or documents, standards and scientific pharmaceuticals, plays an increasingly principles are adopted and similar important role in helping to address rising regulatory practices and procedures are health care costs and in promoting access introduced.

  • Chapter 7: Monogenic Forms of Diabetes
    CHAPTER 7 MONOGENIC FORMS OF DIABETES Mark A. Sperling, MD, and Abhimanyu Garg, MD Dr. Mark A. Sperling is Emeritus Professor and Chair, University of Pittsburgh, Department of Pediatrics, Children’s Hospital of Pittsburgh of UPMC, Pittsburgh, PA. Dr. Abhimanyu Garg is Professor of Internal Medicine and Chief of the Division of Nutrition and Metabolic Diseases at University of Texas Southwestern Medical Center, Dallas, TX. SUMMARY Types 1 and 2 diabetes have multiple and complex genetic influences that interact with environmental triggers, such as viral infections or nutritional excesses, to result in their respective phenotypes: young, lean, and insulin-dependence for type 1 diabetes patients or older, overweight, and often manageable by lifestyle interventions and oral medications for type 2 diabetes patients. A small subset of patients, comprising ~2%–3% of all those diagnosed with diabetes, may have characteristics of either type 1 or type 2 diabetes but have single gene defects that interfere with insulin production, secretion, or action, resulting in clinical diabetes. These types of diabetes are known as MODY, originally defined as maturity-onset diabetes of youth, and severe early-onset forms, such as neonatal diabetes mellitus (NDM). Defects in genes involved in adipocyte development, differentiation, and death pathways cause lipodystrophy syndromes, which are also associated with insulin resistance and diabetes. Although these syndromes are considered rare, more awareness of these disorders and increased availability of genetic testing in clinical and research laboratories, as well as growing use of next generation, whole genome, or exome sequencing for clinically challenging phenotypes, are resulting in increased recognition. A correct diagnosis of MODY, NDM, or lipodystrophy syndromes has profound implications for treatment, genetic counseling, and prognosis.

Study Design: Randomized controlled trial. Place and Duration of Study: Dermatology department, Pak Emirates Military Hospital Rawalpindi, from Oct 2016 to Apr 2017. Material and Methods: Sixty patients of Pityriasis versicolor, both male and female were included in study. Diagnosis of Pityriasis versicolor was made clinically and confirmed microscopically by examining skin scrapings for fungal hyphae. Patients with concomitant systemic illnesses or those who had received anti-fungal in last three months were excluded from study. Random number tables were used to allocate patients to the two treatment groups. Group A received 2% ketoconazole shampoo twice per week for four weeks plus topical 1% clotrimazole twice daily application for 2 weeks. Group B received only topical therapy with 1% clotrimazole cream applied twice daily for 2 weeks. Assessment of treatment efficacy was done by clinical examination of patient and microscopy of skin scrapping for fungal hyphaedone at baseline and at end of study (4 weeks of treatment). A negative clinical examination and negative skin scrapping for fungal hyphae was considered effective therapeutic response.

  • Antifungals, Topical
    Therapeutic Class Overview Antifungals, Topical INTRODUCTION The topical antifungals are available in multiple dosage forms and are indicated for a number of fungal infections and related conditions. In general, these agents are Food and Drug Administration (FDA)-approved for the treatment of cutaneous candidiasis, onychomycosis, seborrheic dermatitis, tinea corporis, tinea cruris, tinea pedis, and tinea versicolor (Clinical Pharmacology 2018). The antifungals may be further classified into the following categories based upon their chemical structures: allylamines (naftifine, terbinafine [only available over the counter (OTC)]), azoles (clotrimazole, econazole, efinaconazole, ketoconazole, luliconazole, miconazole, oxiconazole, sertaconazole, sulconazole), benzylamines (butenafine), hydroxypyridones (ciclopirox), oxaborole (tavaborole), polyenes (nystatin), thiocarbamates (tolnaftate [no FDA-approved formulations]), and miscellaneous (undecylenic acid [no FDA-approved formulations]) (Micromedex 2018). The topical antifungals are available as single entity and/or combination products. Two combination products, nystatin/triamcinolone and Lotrisone (clotrimazole/betamethasone), contain an antifungal and a corticosteroid preparation. The corticosteroid helps to decrease inflammation and indirectly hasten healing time. The other combination product, Vusion (miconazole/zinc oxide/white petrolatum), contains an antifungal and zinc oxide. Zinc oxide acts as a skin protectant and mild astringent with weak antiseptic properties and helps to

  • Steroid Use in Prednisone Allergy Abby Shuck, Pharmd Candidate
    Steroid Use in Prednisone Allergy Abby Shuck, PharmD candidate 2015 University of Findlay If a patient has an allergy to prednisone and methylprednisolone, what (if any) other corticosteroid can the patient use to avoid an allergic reaction? Corticosteroids very rarely cause allergic reactions in patients that receive them. Since corticosteroids are typically used to treat severe allergic reactions and anaphylaxis, it seems unlikely that these drugs could actually induce an allergic reaction of their own. However, between 0.5-5% of people have reported any sort of reaction to a corticosteroid that they have received.1 Corticosteroids can cause anything from minor skin irritations to full blown anaphylactic shock. Worsening of allergic symptoms during corticosteroid treatment may not always mean that the patient has failed treatment, although it may appear to be so.2,3 There are essentially four classes of corticosteroids: Class A, hydrocortisone-type, Class B, triamcinolone acetonide type, Class C, betamethasone type, and Class D, hydrocortisone-17-butyrate and clobetasone-17-butyrate type. Major* corticosteroids in Class A include cortisone, hydrocortisone, methylprednisolone, prednisolone, and prednisone. Major* corticosteroids in Class B include budesonide, fluocinolone, and triamcinolone. Major* corticosteroids in Class C include beclomethasone and dexamethasone. Finally, major* corticosteroids in Class D include betamethasone, fluticasone, and mometasone.4,5 Class D was later subdivided into Class D1 and D2 depending on the presence or 5,6 absence of a C16 methyl substitution and/or halogenation on C9 of the steroid B-ring. It is often hard to determine what exactly a patient is allergic to if they experience a reaction to a corticosteroid.

  • Therapeutic Class Overview Antifungals, Topical
    Therapeutic Class Overview Antifungals, Topical INTRODUCTION The topical antifungals are available in multiple dosage forms and are indicated for a number of fungal infections and related conditions. In general, these agents are Food and Drug Administration (FDA)-approved for the treatment of cutaneous candidiasis, onychomycosis, seborrheic dermatitis, tinea corporis, tinea cruris, tinea pedis, and tinea versicolor (Clinical Pharmacology 2018). The antifungals may be further classified into the following categories based upon their chemical structures: allylamines (naftifine, terbinafine [only available over the counter (OTC)]), azoles (clotrimazole, econazole, efinaconazole, ketoconazole, luliconazole, miconazole, oxiconazole, sertaconazole, sulconazole), benzylamines (butenafine), hydroxypyridones (ciclopirox), oxaborole (tavaborole), polyenes (nystatin), thiocarbamates (tolnaftate [no FDA-approved formulations]), and miscellaneous (undecylenic acid [no FDA-approved formulations]) (Micromedex 2018). The topical antifungals are available as single entity and/or combination products. Two combination products, nystatin/triamcinolone and Lotrisone (clotrimazole/betamethasone), contain an antifungal and a corticosteroid preparation.

Zinc oxide acts as a skin protectant and mild astringent with weak antiseptic properties and helps to
