Abstract
The results show limited effectiveness of all four antifungal drugs. In view of cure rates and the number needed to treat, itraconazole is the most effective drug, followed by fluconazole (daily), terbinafine and then griseofulvin, in chronic and chronic relapsing dermatophytosis in India. What is already known about this topic? Oral antifungal drugs are considered to have a high cure rate in tinea corporis, tinea cruris and tinea faciei. Unprecedented changes have been noticed in the last few years in India in the morphology, course and treatment responsiveness of tinea; however, data about the effectiveness of oral antifungals are lacking. What does this study add? Our results show limited effectiveness of four oral antifungal drugs (fluconazole, griseofulvin, itraconazole and terbinafine) in the current epidemic of altered dermatophytosis in India. Among the four drugs tested, oral itraconazole is the most effective. Linked Comment: Elewski. Br J Dermatol 2020; 183:798-799.
