Fluconazole, itraconazole and ketoconazole in-vitro activity. A comparative study.
We compared in-vitro activity of fluconazole, itraconazole and ketoconazole by evaluating their Minimal Inhibitory Concentrations (MICs) for 100 fungal strains isolated from different biological specimens of ARC/AIDS patients. A semisolid agar medium was used: this method is suitable for testing molds and yeasts, and can be applied to all azole antifungal drugs. Fluconazole had higher MICs than two other tested drugs, especially for Candida krusei strains; however it never had a MIC higher than 40 mg/l. Itraconazole and ketoconazole had MICs higher than 40mg/l for one Cryptococcus neoformans strain. There were no significant differences for itraconazole and ketoconazole among the tested strains.
