adult control subjects. Naftifine hydrochloride gel 2% was well tolerated during the 14-day treatment period. Only two pediatric subjects (9%) and one adult subject (17%) experienced a treatment emergent adverse event and in all cases these adverse events were found to be unrelated to treatment and resolved prior to the end of the study.
Overall, as demonstrated in this maximal use pharmacokinetic study, as well as previous clinical trials,19 naftifine hydrochloride gel 2% was found to be safe, well tolerated, and efficacious for the treatment of tinea pedis in a pediatric and adult population.
