Effect of fluvastatin and pravastatin, HMG-CoA reductase inhibitors, on fluconazole activity against Candida albicans

J Med Microbiol. 2002 Feb;51(2):105-109. doi: 10.1099/0022-1317-51-2-105.

Abstract

Synergy between fluvastatin, at clinically unachievable concentrations, and fluconazole against Candida albicans has been reported. The purpose of the present study was to evaluate the in-vitro activity of fluconazole alone and in combination with clinically achievable concentrations of pravastatin and fluvastatin against C. albicans. In-vitro susceptibility and synergy testing were performed against clinical isolates of C. albicans with fluconazole, pravastatin and fluvastatin. Both checkerboard method and time-kill studies were performed. MICs for fluconazole ranged from 0.5 (susceptible) to >256 mg/L (resistant) at 24 h. All isolates had MICs >2 mg/L for both statins. No synergy or antagonism was observed with fluconazole in combination with either agent against any isolate of C. albicans by the checkerboard assay or time-kill studies. Clinically achievable concentrations of pravastatin and fluvastatin did not affect the in-vitro activity of fluconazole against C. albicans.
