Action/Kinetics:
Synthetic antifungal agent with a broad spectrum of activity. Thought to inhibit squalene 2,3-epoxidase, which is responsible for synthesis of sterols. The decreased levels of sterols (especially ergosterol) and the accumulation of squalene in cells result in fungicidal activity. Although used topically, approximately 6% of the drug is absorbed. Naftifine and its metabolites are excreted via the feces and urine.
