Novel, single-dose, topical treatment of tinea pedis using terbinafine: results of a dose-finding clinical trial.

Tinea pedis is the most common dermatophytosis requiring topical antifungals for at least 1-4 weeks. To determine the effectiveness of a novel topical single dose formulation of terbinafine (film forming solution-FFS) in the treatment of tinea pedis, 344 outpatients from 43 dermatological centres in France and Bulgaria suffering from tinea pedis with possible extension to soles confirmed by mycological examination (direct and culture) were evaluated for efficacy of terbinafine 1%, 5%, 10% FFS in a randomised double blind vehicle controlled parallel group dose finding study. Evaluations were carried out at baseline, 1 and 6 weeks after a single application of FFS.
