Photodegradation Assessment of Ciprofloxacin, Moxifloxacin
Hubicka et al. Chemistry Central Journal 2013, 7:133 http://journal.chemistrycentral.com/content/7/1/133 RESEARCH ARTICLE Open Access Photodegradation assessment of ciprofloxacin, moxifloxacin, norfloxacin and ofloxacin in the presence of excipients from tablets by UPLC-MS/MS and DSC Urszula Hubicka1*, PawełŻmudzki2, Przemysław Talik1, Barbara Żuromska-Witek1 and Jan Krzek1 Abstract Background: Ciprofloxacin (CIP), moxifloxacin (MOX), norfloxacin (NOR) and ofloxacin (OFL), are the antibacterial synthetic drugs, belonging to the fluoroquinolones group. Fluoroquinolones are compounds susceptible to photodegradation process, which may lead to reduction of their antibacterial activity and to induce phototoxicity as a side effect. This paper describes a simple, sensitive UPLC-MS/MS method for the determination of CIP, MOX, NOR and OFL in the presence of photodegradation products. Results: Chromatographic separations were carried out using the Acquity UPLC BEH C18 column; (2.1 × 100 mm, 1.7 μm particle size). The column was maintained at 40°C, and the following gradient was used: 0 min, 95% of eluent A and 5% of eluent B; 10 min, 0% of eluent A and 100% of eluent B, at a flow rate of 0.3 mL min-1. Eluent A: 0.1% (v/v) formic acid in water; eluent B: 0.1% (v/v) formic acid in acetonitrile. The method was validated and all the validation parameters were in the ranges acceptable by the guidelines for analytical method validation. The photodegradation of examined fluoroquinolones in solid phase in the presence of excipients followed kinetic of the first order reaction and depended upon the type of analyzed drugs and coexisting substances. -

Use of Antipsychotic Medications in Nursing Facility Residents
POLICY Use of Antipsychotic Medications in Nursing Facility Residents Preamble The Office of Inspector General of the U. S. Department of Health and Human Services issued a report in May 2011 finding that 14% of elderly nursing home residents had Medicare claims for atypical antipsychotic drugs.1 In addition, 83% of the above Medicare claims for atypical antipsychotics for these elderly nursing home residents were for off---label indications. In 2005, the U. S. Food and Drug Administration required manufacturers of atypical antipsychotic medications to include a boxed warning that these antipsychotics may increase the risk of death in elderly persons with psychosis related to dementia. This warning was expanded to all antipsychotic drugs in 2008. The OIG report found that 88% of the use of atypical antipsychotics was in persons for whom this warning is applicable. As part of the report, OIG conducted medical record reviews on 600 elderly nursing facility residents. They found that 22% of the atypical antipsychotic medications were not administered in accordance with standards from the Centers for Medicare & Medicaid Services relating to unnecessary drug use in nursing homes. This controversial report from the OIG has generated concern about the use of antipsychotics in patients with dementia, and also criticism of the report itself.2 ---4 This document will provide additional background on this subject and a position statement from the American Society of Consultant Pharmacists. Background Understanding the findings and implications of the OIG report on use of atypical antipsychotics in nursing home residents requires placing the report findings into a proper context. Shown below are key points to understanding this report. -

Therapeutic Class Overview Fluoroquinolones
Therapeutic Class Overview Fluoroquinolones INTRODUCTION The fluoroquinolones are broad-spectrum antibiotics grouped into generations based on their spectrum of activity (Bolon 2011). ○ First generation agents, which are structurally quinolones rather than fluoroquinolones, possess activity against aerobic gram-negative bacteria but are not effective against aerobic gram-positive bacteria or anaerobes. The first generation agents (eg, nalidixic acid, cinoxacin) are no longer on the market. ○ Second generation agents, the original fluoroquinolones, contain a fluorine atom at position C-6. These agents offer improved coverage against gram-negative bacteria and moderately improved gram-positive coverage. The available second generation fluoroquinolones include ciprofloxacin, levofloxacin, and ofloxacin. Lomefloxacin and norfloxacin are second generation agents which are no longer on the market. ○ Third generation agents achieve greater potency against gram-positive bacteria, particularly pneumococci, and also possess good activity against anaerobes. All 3 of the third generation agents, gatifloxacin, grepafloxacin, and sparfloxacin, were removed from the market due to toxicities. ○ Fourth generation fluoroquinolones have superior coverage against pneumococci and anaerobes. The available agent is moxifloxacin. Trovafloxacin, was removed from the market due to toxicities, and there is a drug shortage of gemifloxacin. ○ The most recently approved fluoroquinolone, delafloxacin, has an even broader spectrum of antibiotic activity and is commonly referred to as a “next generation” fluoroquinolone. The fluoroquinolones have been used to treat a variety of infections including urinary tract infections, sinusitis, lower respiratory tract infections, intra-abdominal infections, infectious diarrhea, skin and skin structure infections, sexually transmitted diseases, and bacterial prostatitis. A few of the agents also have Food and Drug Administration (FDA) approval for inhalational anthrax and plague. -

Allergy to Quinolones: Low Cross-Reactivity to Levofloxacin
T Lobera, et al ORIGINAL ARTICLE Allergy to Quinolones: Low Cross-reactivity to Levofl oxacin T Lobera,1 MT Audícana,2 E Alarcón,1 N Longo,2 B Navarro,1 D Muñoz2 1Department of Allergy, Hospital San Pedro/San Millán, Logroño, Spain 2Department of Allergy, Hospital Santiago Apóstol, Vitoria, Spain ■ Abstract Background: Immediate-type hypersensitivity reactions to quinolones are rare. Some reports describe the presence of cross-reactivity among different members of the group, although no predictive pattern has been established. No previous studies confi rm or rule out cross-reactivity between levofl oxacin and other quinolones. Therefore, a joint study was designed between 2 allergy departments to assess cross-reactivity between levofl oxacin and other quinolones. Material and Methods: We studied 12 patients who had experienced an immediate-type reaction (4 anaphylaxis and 8 urticaria/angioedema) after oral administration of quinolones. The culprit drugs were as follows: ciprofl oxacin (5), levofl oxacin (4), levofl oxacin plus moxifl oxacin (1), moxifl oxacin (1), and norfl oxacin (1). Allergy was confi rmed by skin tests and controlled oral challenge tests with different quinolones. The basophil activation test (BAT) was applied in 6 patients. Results: The skin tests were positive in 5 patients with levofl oxacin (2), moxifl oxacin (2), and ofl oxacin (2). BAT was negative in all patients (6/6). Most of the ciprofl oxacin-reactive patients (4/5) tolerated levofl oxacin. Similarly, 3 of 4 levofl oxacin-reactive patients tolerated ciprofl oxacin. Patients who reacted to moxifl oxacin and norfl oxacin tolerated ciprofl oxacin and levofl oxacin. Conclusions: Our results suggest that skin testing and BAT do not help to identify the culprit drug or predict cross-reactivity. -
Reduced Moxifloxacin Exposure in Patients with Tuberculosis and Diabetes
AGORA | RESEARCH LETTER Reduced moxifloxacin exposure in patients with tuberculosis and diabetes To the Editor: Prevalence of diabetes mellitus (DM) in patients with tuberculosis (TB) is increasing and may negatively impact TB outcomes in patients with active disease [1]. Gastrointestinal problems, including gastroparesis, may result in delayed drug absorption or malabsorption in patients with DM, which may cause suboptimal drug exposure and poor outcome [2]. Studies on the pharmacokinetics of the first-line anti-TB drugs in patients with DM yielded conflicting results on low drug exposure [3–7]. Moxifloxacin is a potent bactericidal drug against Mycobacterium tuberculosis and is key for the treatment of multidrug-resistant tuberculosis (MDR)-TB [8]. Moreover, moxifloxacin can be recommended for TB treatment in patients with monoresistance or intolerance to first-line drugs [9]. Recently, we reported on a patient with TB and DM in whom moxifloxacin exposure was reduced [10]. In this study, we aimed to evaluate moxifloxacin drug exposure in patients with TB and DM. We retrospectively identified all patients aged ⩾16 years who underwent routine therapeutic drug monitoring (TDM) using at least three time-points for moxifloxacin as part of their TB treatment at our centre in the period 2006–2018. For this study, the Medical Ethical Committee of the University Medical Center Groningen (Groningen, the Netherlands) waived the need for written informed consent due to the retrospective nature of the study (reference 2013/492). Patient data were processed according to the Declaration of Helsinki. Controls were TB patients without DM matched for age, sex and rifampicin use (cases/controls 1/1). -
