Itraconazole pulse therapy for onychomycosis and dermatomycoses: an overview.
BACKGROUND
Itraconazole is a broad-spectrum antifungal agent that has been used to treat dermatomycosis and onychomycosis using continuous therapy. More recently the drug has been used as pulse dosing.


OBJECTIVE
Our purpose was to review the studies in which itraconazole pulse therapy (PT) has been administered in the management of dermatomycoses.


RESULTS
For tinea pedis and manuum, the recommended dosage is itraconazole 200 mg twice daily for 1 week (n = 220). A clinical response and mycologic cure rate of 90% +/- 4% and 76% +/- 6%, respectively, has been obtained. For tinea corporis/cruris, itraconazole 200 mg/day for 1 week (n = 354) resulted in a clinical response and mycologic cure rate of 90% +/- 4% and 77% +/- 6%, respectively. When three pulses of itraconazole are used to treat toenail onychomycosis (n = 1389), the clinical cure rate, clinical response, and mycologic cure rate at follow-up 12 months after the start of therapy were 58% +/- 10%, 82% +/- 3%, and 77% +/- 5%, respectively. With two pulses for onychomycosis of the fingernails, the clinical cure rate, clinical response, and mycologic cure rate at follow-up, 9 months after the start of therapy, were 78% +/- 10%, 89% +/- 6%, and 87% +/- 8%, respectively.


CONCLUSIONS
Itraconazole PT is effective and safe in the treatment of tinea pedis/manuum, tinea corporis/cruris, and onychomycosis.
