Treatment of tinea pedis interdigitalis with bifonazole, 1% gel

329 adult patients with tinea pedis interdigitalis, which clinical diagnosis was confirmed by positive direct microscopic examinations and cultures of organisms from the lesions, were enrolled in this open and multicentric study. Informed consent was requested and obtained in each case. The bifonazole, 1% gel, tested was applied topically once daily for 3 weeks. Weekly clinical controls were performed during the treatment period and, at least, two clinical mycological posttreatment assessments were carried out. The evaluation criteria were based on the clinical and mycological findings at the end of the second posttreatment week. According to these criteria, the results obtained were: very good (clinical cure, negative mycology) 276 (84.0%); good (clinical improvement, negative mycology) 32 (9.5%); moderate (clinical improvement, positive mycology) 20 (6.0%), and failure (no clinical and mycological changes) 1 (0.5%). Tolerance was excellent, side effects were not observed in any case.
