Comparative Study Clinical Trial Controlled Clinical TrialMetabolic effects of low-dose fluconazole in healthy female users and non-users of oral contraceptives.
1. Azole antifungal agents such as ketoconazole act by inhibiting cytochrome P-450 mediated sterol synthesis in the fungal cell membrane and thus have the potential to interfere with mammalian steroidogenesis. Fluconazole is a novel orally-effective antifungal triazole which has been reported to have more specific effects on the cytochrome P-450 enzymes involved in fungal sterol synthesis. 2. ⋯ Minor biochemical changes associated with fluconazole treatment included increases in serum thyroxine and testosterone concentrations (but not in women taking OC as well as fluconazole) and in insulin and apolipoprotein B levels (but only in women taking OC as well as fluconazole). In general, these changes were small and of no clinical significance with the values remaining within the laboratory normal range. There were no adverse side-effects.(ABSTRACT TRUNCATED AT 250 WORDS)
