Therapeutic effects of omoconazole nitrate on experimental tinea pedis, an intractable dermatophytosis, in guinea-pigs.

The therapeutic efficacy of omoconazole nitrate was investigated in an experimental tinea pedis model produced by topical inoculation with Trichophyton mentagrophytes in guinea-pigs, which is pathologically similar to naturally infected tinea pedis in humans. Treatment with omoconazole nitrate cream was started on week 2 postinfection and continued for 3 or 4 weeks. Once-a-day application of 1% omoconazole nitrate to the site of infection exhibited an excellent therapeutic efficacy, and was superior to 1% bifonazole cream in culture result. This result suggests that omoconazole nitrate has a potential usefulness for the treatment of tinea pedis in humans.
