Nystatin-Neomycin-Polymyxin B Combination: Efficacy and Tolerance as 1st-Line Local Treatment of Infectious Vaginitis


Objective: To evaluate the efficacy and tolerance of a local treatment combining two antibacterials and one antifungal in patients with a clinical presentation suggesting infectious vaginitis. Patients and methods: 169 patients presenting with clinical criteria for vaginitis were included in an open, multicenter trial. Vaginal samples were taken for microbiological analyses and a triple-combination product of nystatin, neomycin and polymyxin B was then started as local treatment, without waiting for the test results. The treatment was continued with the usual dosage (1 vaginal capsule at bedtime for 12 days) for vaginal infections in the scope of the combination product with approved labeling. A second vaginal sample was performed at the end of the treatment. The main efficacy criterion was the clinical success rate (cure or improvement of the clinical signs and symptoms) according to the investigator.Results: 93 patients were included in the efficacy population. Non-exclusively fungal vaginitis (strictly bacterial or bacterial + fungal) represented 31.2% of the cases. The clinical success rate was 97.8% according to the investigator and 95.7% according to the patients. The microbiological success rate was 81.3%, with no differences between etiologies (Candida spp., bacteria or both). The combination product was well-tolerated, despite the local inflammation before treatment. Discussion and conclusion: Given the etiological diversity of vaginitis, this trial supports the efficacy of a triple-combination product (nystatin, neomycin, polymyxin B) as a first-line local treatment of Candida, bacterial or mixed vaginitis.
