Pharmacology
Indication For the treatment of fungal infections.
Pharmacodynamics Fluconazole, a synthetic antifungal agent of the imidazole class, is used to treat vaginal candidiasis. It inhibits the fungal lanosterol 14 alpha-demethylase which thereby prevents the formation of ergosterol which is an essential component in the fungal cell membrane.
Mechanism of action Fluconazole interacts with 14-α demethylase, a cytochrome P-450 enzyme necessary to convert lanosterol to ergosterol. As ergosterol is an essential component of the fungal cell membrane, inhibition of its synthesis results in increased cellular permeability causing leakage of cellular contents. Fluconazole may also inhibit endogenous respiration, interact with membrane phospholipids, inhibit the transformation of yeasts to mycelial forms, inhibit purine uptake, and impair triglyceride and/or phospholipid biosynthesis.
Absorption 90%

Route of elimination In normal volunteers, fluconazole is cleared primarily by renal excretion, with approximately 80% of the administered dose appearing in the urine as unchanged drug.

Enzymes

1. Cytochrome P450 3A4

Actions: inhibitor

Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It performs a variety of oxidation reactions (e.g. caffeine 8-oxidation, omeprazole sulphoxidation, midazolam 1'-hydroxylation and midazolam 4- hydroxylation) of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. The enzyme also hydroxylates etoposide
