[Therapy of nail mycoses]

Abstract:
Onchomycosis is the most common nail disease, accounting for approximately 30% of all cutaneous fungal infections. The treatment approach needs to take into account the location and extent of onychomycosis, sensitivity of drug to fungal organism, adverse-effects profile, dosage schedule, duration of therapy, concomitant medical conditions, and concurrent medications. To confirm the diagnosis, it is important to correctly select the appropriate site for specimen collection used for both direct microscopy and fungal culture. Topical antifungal agents may be considered for the treatment of early onychomycosis, in the absence of nail matrix involvement. The newer generation of oral antifungal agents for the treatment of onychomycosis are terbinafine, itraconazole and fluconazole. These drugs used alone, or in combination with topical antifungals, are providing the basis for effective treatment of onychomycosis in a large proportion of patients.
