Butenafine: an update of its use in superficial mycoses.

Butenafine is a synthetic benzylamine antifungal agent that may be fungicidal against susceptible organisms, e.g., dermatophytes. Butenafine may be effective and safe in the treatment of interdigital tinea pedis (apply twice daily for 1 week or once daily for 4 weeks), tinea corporis/tinea cruris (apply twice daily for 2 weeks), and pityriasis versicolor (apply once daily for 2 weeks). The effectiveness of the drug persists for at least 4 weeks following the discontinuation of therapy suggesting that there is some retention of the drug in the skin following termination of active therapy.
