In-vitro comparative activity of UR-9825, itraconazole and fluconazole against clinical isolates of Candida spp.

UR-9825 is a new broad-spectrum triazole antifungal agent with a good pharmacokinetic profile and excellent bioavailability. It shows high in-vitro activity and efficacy in models of systemic candidosis in rats and rabbits, comparing favourably with fluconazole. The purpose of this study was to evaluate the in-vitro activity of UR-9825 and to compare it with that of fluconazole and itraconazole against 283 clinical isolates of Candida spp. UR-9825 was more potent against Candida spp. than both fluconazole and itraconazole, even against some Candida albicans and Candida krusei isolates with decreased susceptibility to fluconazole (MIC 16 mg/L).
