Due to the increasing resistance of various Candida species to azole drugs, particularly fluconazole, it would be of significant importance to look for alternative therapies. The aim of this study was to investigate the antifungal activity of capric acid and its in vitro interactions with nystatin and fluconazole against Candida isolates. A total of 40 Candida isolates (C. albicans, 36; C. kefyr, 2; C. tropicalis, 1; C. glabrata, 1) collected from the oral cavity of neonates with oropharyngeal candidiasis and a reference strain of C. albicans (ATCC 10231) were used in this study. Antifungal activity of capric acid and two comparator antifungal drugs, namely fluconazole and nystatin, was tested according to CLSI M27-A3/M60 method. The in vitro interaction between capric acid with fluconazole and nystatin was determined following a checkerboard method and results were interpreted using fractional inhibitory concentration index. Nystatin had the lowest minimum inhibitory concentrations (range, 0.125–8 μg/mL; geometric mean [GM], 0.6229 μg/mL) followed by fluconazole (range, 0.5–16 μg/mL; GM, 1.9011 μg/mL) and capric acid (range, 128–2,048 μg/mL; GM, 835.9756 μg/mL). When tested in combination, capric acid with fluconazole demonstrated synergistic, indifferent, and antagonistic interactions in 3 (7.317%), 24 (58.536%), and 14 (34.146%) cases, respectively. For combination of capric acid with nystatin, synergistic, indifferent, and antagonistic interactions were observed in 1 (2.439%), 19 (46.341%), and 21 (51.219%) cases, respectively. All cases of synergistic interactions were against resistant or susceptible dose-dependent isolates. Fluconazole, nystatin, and capric acid seem to be more effective when they are used alone compared with their combination. However, their combination might be effective on resistant isolates.
