Bifonazole (Mycospor cream) in the treatment of moccasin-type tinea pedis. Comparison between combination therapy of bifonazole cream + 10% urea ointment (Urepearl) and occlusive dressing therapy with the same agents.

Moccasin-type tinea pedis(MTTP) is a hardly curable superficial dermatomycosis primarily characterized by hyperkeratosis of the sole. In this study, we compared the usefulness of combination therapy of bifonazole (Mycospor cream) + 10% urea ointment (Urepearl) (overlapping application group = group I) with occlusive dressing therapy with the same agents (group II) in the treatment of MTTP, and obtained the following results. (1) The clinical improvement rate (percentage of "marked improvement" and "moderate improvement") was 60.4% in group I and 83.3% in group II. (2) The mycological eradication rate was 48.7% in group I and 82.1% in group II after 4 weeks of treatment and 90.9 and 96.9%, after 12 weeks of treatment, respectively. (3) The clinical utility rate (percentage of "very beneficial" and "beneficial") was 83.3% in group I and 93.8% in group II. These results indicate the superiority of both combination therapy of bifonazole + 10% urea ointment (overlapping application group) and occlusive dressing therapy with the same agents in terms of efficacy and safety for the treatment of MTTP, and suggest that they can be recommended for treatment of patients for whom it is difficult to use oral antimycotic agents or for patients who fail to respond to oral medications alone.
