Butenafine is a topical antifungal used to treat tinea versicolor, tinea pedis, tinea cruris, and tinea corporis.
Although the mechanism of action has not been fully established, it has been suggested that butenafine, like allylamines, interferes with sterol biosynthesis (especially ergosterol) by inhibiting squalene monooxygenase, an enzyme responsible for converting squalene to 2,3-oxydo squalene. As ergosterol is an essential component of the fungal cell membrane, inhibition of its synthesis results in increased cellular permeability causing leakage of cellular contents. Blockage of squalene monooxygenase also leads to a subsequent accumulation of squalene. When a high concentration of squalene is reached, it is thought to have an effect of directly kill fungal cells.
For the topical treatment of the following dermatologic infections: tinea (pityriasis) versicolor due to M. furfur, interdigital tinea pedis (athlete’s foot), tinea corporis (ringworm) and tinea cruris (jock itch) due to E. floccosum, T. mentagrophytes, T. rubrum, and T. tonsurans.
