Drug information of Fluconazole


Drug group:

Fluconazole is an antifungal medicine. Fluconazole is used to treat infections caused by fungus, which can invade any part of the body including the mouth, throat, esophagus, lungs, bladder, genital area, and the blood. Fluconazole is also used to prevent fungal infection in people who have a weak immune system caused by cancer treatment, bone marrow transplant, or diseases such as AIDS.

Mechanism of effect

Fluconazole is a highly selective inhibitor of fungal cytochrome P450 dependent enzyme lanosterol 14-α-demethylase. This enzyme functions to convert lanosterol to ergosterol. The subsequent loss of normal sterols correlates with the accumulation of 14-α-methyl sterols in fungi and may be responsible for the fungistatic activity of Fluconazole. Mammalian cell demethylation is much less sensitive to Fluconazole inhibition.


Fluconazole, a synthetic antifungal agent of the imidazole class, is used to treat vaginal candidiasis.
