Onychomycosis is a very common nail disorder seen in dermatological practice. It is difficult to treat successfully for a multitude of
reasons, and although topical antifungal therapy might be considered ideal for mild to moderate onychomycosis, efficacy has been
limited by poor nail penetration of active ingredient through the nail plate into the nail bed and nail matrix to the site of infection. The
intrinsic properties of an antifungal and its vehicle formulation are both considered important contributors to effective treatment.
Here we review the formulation approach to efinaconazole topical solution, 10% an effective and well-tolerated treatment for onychomycosis.
We demonstrate that the low surface tension formulation affords better penetration of efinaconazole through the nail
plate, and also to the site of infection by spreading into the space between the nail and nail bed. J Drugs Dermatol.
