Treatment of chronic tinea pedis (athlete's foot type) with topical terbinafine.

Abstract

Twenty-seven patients with chronic tinea pedis, athlete's foot type, were enrolled in a randomized, double-blind trial of topical treatment with terbinafine 1% cream versus its vehicle (placebo). Patients were examined weekly during 4 weeks of twice-daily treatment and at follow-up 2 weeks after the conclusion of therapy. No adverse events were reported in either treatment group. Drug efficacy was evaluated in 22 patients, of whom nine (41%) were treated with terbinafine and 13 (59%) with placebo. Analysis of combined mycologic and clinical results showed that terbinafine was significantly more effective than placebo at the end of therapy (78% vs zero) and at the 2-week follow-up (89% vs zero) (p less than or equal to 0.001 at both intervals.
