What is fluconazole used for?
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.
How is fluconazole cleared?
In normal volunteers, Fluconazole is cleared primarily by renal excretion, with approximately 80% of the administered dose appearing in the urine as unchanged drug.

Is fluconazole a CYP3A4 inhibitor?
(See CONTRAINDICATIONS .) Fluconazole is a moderate CYP2C9 and CYP3A4 inhibitor. Flucona zole is also a strong inhibitor of CYP2C19. Patients treated with Fluconazole, who are also concomitantly treated with drugs with a narrow therapeutic window metabolized through CYP2C9 and CYP3A4, should be monitored for adverse reactions associated with the concomitantly administered drugs. In addition to the observed/documented interactions mentioned below, there is a risk of increased plasma concentration of other compounds metabolized by CYP2C9, CYP2C19, and CYP3A4 co-administered with Fluconazole. Therefore, caution should be exercised when using these combinations and the patients should be carefully monitored. The enzyme inhibiting effect of Fluconazole persists 4 to 5 days after discontinuation of Fluconazole treatment due to the long half-life of Fluconazole. Clinically or potentially significant drug interactions between Fluconazole and the following agents/classes have been observed and are described in greater detail below:

Fluconazole for Oral Suspension contains 350 mg or 1400 mg of Fluconazole and...
Side effects
- The pharmacokinetic properties of Fluconazole are similar following administration by the intravenous or oral routes. In normal volunteers, the bioavailability of orally administered Fluconazole is over 90% compared with intravenous administration. Bioequivalence was established between the 100 mg tablet and both suspension strengths when administered as a …
Epidemiology
- The Cmax and AUC data from a food-effect study involving administration of Fluconazole tablets to healthy volunteers under fasting conditions and with a high-fat meal indicated that exposure to the drug is not affected by food. Therefore, Fluconazole may be taken without regard to meals. (See DOSAGE AND ADMINISTRATION)
Example
- A single oral 150 mg dose of Fluconazole administered to 27 patients penetrated into vaginal tissue, resulting in tissue: plasma ratios ranging from 0.94 to 1.14 over the first 48 hours following dosing. A single oral 150 mg dose of Fluconazole administered to 14 patients penetrated into vaginal fluid, resulting in fluid: plasma ratios ranging from 0.36 to 0.71 over the first 72 hours foll…
Administration
- In normal volunteers, Fluconazole administration (doses ranging from 200 mg to 400 mg once daily for up to 14 days) was associated with small and inconsistent effects on testosterone concentrations, endogenous corticosteroid concentrations, and the adrenocorticotropic hormone (ACTH)-stimulated cortisol response.
Interactions
- Clearance corrected for body weight was not affected by age in these studies. Mean body clearance in adults is reported to be 0.23 (17%) mL/min/kg.
Safety
- In premature newborns (gestational age 26 to 29 weeks), the mean (%cv) clearance within 36 hours of birth was 0.180 (35%, N=7) mL/min/kg, which increased with time to a mean of 0.218 (31%, N=9) mL/min/kg six days later and 0.333 (56%, N=4) mL/min/kg 12 days later. Similarly, the half-life was 73.6 hours, which decreased with time to a mean of 53.2 hours six days later and 4…

In this placebo-controlled, double-blind, randomized, two-way crossover study carried out over three cycles of oral contraceptive treatment, Fluconazole dosing resulted in small increases in the me…
Mechanism of action
- Administration of Maalox® (20 mL) to 14 normal male volunteers immediately prior to a single dose of Fluconazole 100 mg had no effect on the absorption or elimination of Fluconazole.
