Objective: To review pharmacokinetics, mechanism of actions and clinical efficacy of butenafine against various dermatophytic and other superficial fungal infections. Methods: Medline search was made using keyword butenafine. All English language articles were considered for this review. For inclusion in clinical efficacy section when ever available randomized controlled trials were considered a priority over other trials. Results/conclusions: The drug has excellent penetration into the epidermis and a prolonged retention time following topical application, conferring residual therapeutic activity after treatment cessation. Butenafine possess anti-inflammatory activity too. Topical butenafine 1% cream has been reported to be efficacious for tinea pedis, tinea corporis and tinea cruris in many randomized clinical trials when used for shorter duration.
