Abstract
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. Conclusion: Itraconazole PT is effective and safe in the treatment of tinea pedis/manuum, tinea corporis/cruris, and onychomycosis. (J Am Acad Dermatol 1997;37:969-74.)
