The combination of fluconazole with either ibuprofen, sodium salicylate, or propylparaben resulted in synergistic activity (fractional inhibitory index, < 0.5) against Candida albicans NCYC 620 in a microdilution checkerboard assay. Synergism between miconazole and ibuprofen was also demonstrated. In three or four clinical isolates of C. albicans from AIDS patients, the combination of fluconazole and ibuprofen was synergistic. Preparation of the inoculum and the growth conditions used were those recommended by the National Committee for Clinical Laboratory Standards for susceptibility testing. A visual estimation of total inhibition of growth and determination of an 80% reduction in the optical density at 492 nm compared with those for the control were taken as endpoints for the calculation of synergy, and a good correlation between both estimates was demonstrated.
