Predicting a therapeutic cut‐off serum level of itraconazole in recalcitrant tinea corporis and cruris—A prospective trial

Abstract

Therapeutic failures are uncommon with itraconazole, and the prevalent strain in India has low itraconazole MICs. Treatment failure is likely with itraconazole serum levels of <0.2 µg/ml, while levels >0.2 µg/ml are consistently associated with a positive therapeutic outcome.
