Efinaconazole 10% solution: a comprehensive review of its use in the treatment of onychomycosis

Efinaconazole 10% solution is an important addition to the armamentarium of therapies available to treat onychomycosis. Certain subgroups respond particularly well: females versus males, children versus adults, early onset onychomycosis (<1-year disease), those with mild onychomycosis (≤25% nail involvement), absence of tinea pedis, and thin nail plates at baseline (<1 mm thickness). Efinaconazole 10% solution is effective in diabetics and has demonstrated efficacy against dermatophytomas. Efinaconazole may be a consideration when terbinafine resistance is a concern, due to its different target of action.
