INFLUENCE OF ASSOCIATING NONSTEROIDAL ANTI-INFLAMMATORY DRUGS WITH ANTIFUNGAL COMPOUNDS ON VIABILITY OF SOME CANDIDA STRAINS
Objective. The main goal of our study was to determine the effect that association of nonsteroidal anti-in- flammatory drugs (NSAIDs) with antifungal drugs on viability of Candida (C.) albicans and C. krusei species. Materials and methods. Six yeast strains were isolated from pharyngeal and vaginal secretions (C. albicans and C. krusei). Tests (diffusion and serial microdilutions methods) were carried out in the presence of some NSAIDs by using different concentrations (0.25mg/ml and 1mg/ml). Antifungal drugs were used in lower concentrations than the MIC (1μg/ml). Results. Cell viability of C. krusei strain was of 82% for NSAIDs used and association of these with ketoconazole led to decrease of cell viability of C. krusei strain to 60% as compared to the cells treated with antifungal drugs. In the presence of NSAIDs, cell viability of C. albicans strains, decreased between 6 to 18% for diclofenac and ibuprofen. In the case of simultaneous use of the two classes of drugs, there was observed an increase of antimicrobial activity, especially for diclofenac association, cell viability was reduced up to 60% and respectively 70% as compared to the cells treated only with ketoconazole and fluconazole. Conclusion. We observed a synergistic action of certain NSAIDs with two antifungal drugs used on some Candida species.
