“…The new triazole fluconazole (FCZ) has proven to be highly effective against oral candidosis in clinical trials (3,6,9,14,16,43), with only low levels of toxicity when given at various dosages and with even higher response rates to treatment than other antifungal agents, e.g., ketoconazole and clotrimazole (5,15,19). Since 1989 fluconazole has widely been used for the prevention and therapy of OPC in HIV-infected patients (14,21,25,26,39). Some earlier reports have already described azole resistance in Candida species (17,30,38,44), but recently, concerns have been raised regarding the development of resistance to FCZ in C. albicans strains isolated from AIDS patients.…”
