Efficacy and safety of nadifloxacin for bacterial skin infections: results from clinical and post-marketing studies.


PMID 25212256

Abstract

Skin and soft tissue infections involve microbial invasion of the skin and underlying soft tissues and are estimated to affect 7-10% of hospitalized patients worldwide. Nadifloxacin, a topical fluoroquinolone, has been shown to be effective against aerobic Gram-negative, Gram-positive (including MRSA and coagulase-negative staphylococci), and anaerobic bacteria. However, there is paucity of data comparing efficacy and safety of 1% nadifloxacin with other anti-bacterials for skin infections in Indian patients. This article presents the results of one post-marketing surveillance (PMS) and three randomized, open, non-blinded, multi-centric clinical studies that compared nadifloxacin with mupirocin and framycetin, and nadifloxacin with fusidic acid. Patients in India, aged from 1 to 65xa0years old, suffering from mild to moderate bacterial skin infections including impetigo, secondarily infected wounds, folliculitis, infected atopic dermatitis, and furunculosis were randomly allocated to three treatment groups within the studies. Efficacy was assessed by the evaluation of symptoms of erythema, exudation, swelling, pruritus, crusting, pain and tenderness in all the studies. A total of 272 subjects were enrolled in the study and subjects were randomly assigned to one of the three treatment groups; 92 in the nadifloxacin group, 90 in the mupirocin group, and 90 in the framycetin group. A significant reduction in the mean scores for bacterial infection symptoms in the nadifloxacin groups was observed when compared to mupirocin, framycetin and fusidic acid groups. Both physician and patients rated nadifloxacin as excellent (complete remission of symptoms) on a 4-point scale in the studies. No adverse events (AEs) were reported in the clinical studies. In the PMS, only two patients (of 329, 0.6%) reported AEs including burning and itching, one in each patient that had resolved at the time of reporting. Nadifloxacin, a fluoroquinolone, is a new alternative topical agent in the treatment of bacterial skin infection with minimal AEs.
