Background : Topical antifungal agents have been ineffective in the treatment of onychomycosis because they could not reach the infected nail bed. 8% ciclopirox nail lacquer is a new topical antimycotic which is characterized by excellent penetration into the nail plate. We performed a study to assess the therapeutic efficacy and safety of 8% ciclopirox nail lacquer in the treatment of onychomycosis.
Methods : We assessed 27 onychomycotic patients whose affected area of target nail plate was not more than 50%. The patients were instructed to apply 8% ciclopirox nail lacquer once daily and evaluated monthly for 6 months. Mycological examinations were done before and after the treatment. Overall efficacy, tolerability, cometic acceptance and adverse effects were assessed at the end of 6 month's treatment.
Results : The mean percentage of affected area decreased from 28.9% to 4.7%. Mycological cure rate was 77.8% at the end of the treatment. Overall efficacy assessed by physician and patients were similar and evaluated as complete cure in 48% and 44%, respectively. Tolerability and cosmetic acceptance were excellent or good in most of the patients. No systemic adverse effects were found, but 3 patients complained of mild prickling sensation or ingrowing toe nail.
Conclusions : These data suggest that 8% ciclopirox nail lacquer is safe and effective in the treatment of mild onychomycosis.
