The dermatopharmacologic profile of ciclopirox 8% nail lacquer.

Ciclopirox 8% nail lacquer is a recently introduced topical formulation of the hydroxypyridone antimycotic ciclopirox. In vitro data indicate that ciclopirox has activity against the important pathogenic dermatophytes responsible for onychomycosis. The lacquer delivery system provides a high concentration gradient for the transfer of the antifungal agent through the nail plate. Daily application to the toenail surface of healthy subjects resulted in good penetration and distribution within all nail layers. Systemic absorption of ciclopirox in five patients with onychomycosis was minimal.
