Fluconazole is an oral antifungal medication that inhibits ergosterol synthesis in fungal cell membranes. It belongs to the triazole class and selectively binds to the cyp51 enzyme required for sterol biosynthesis. By blocking this enzyme the drug impairs membrane integrity and leads to fungal cell death. Its therapeutic purpose is to treat systemic and opportunistic fungal infections such as candidiasis and cryptococcal meningitis. Fluconazole is rapidly absorbed after oral dosing and distributes broadly in body fluids with limited hepatic metabolism. The pharmacological mechanism involves competitive inhibition of lanosterol 14a-demethylase resulting in accumulation of toxic sterol precursors.

Fluconazole is an antifungal medication used to treat systemic and superficial fungal infections. It works by inhibiting the enzyme lanosterol 14a-demethylase which is required for ergosterol synthesis in fungi. By blocking ergosterol production the drug disrupts the fungal cell membrane making it leaky and unable to grow. The medication is absorbed orally and distributes widely throughout body tissues including the brain and lungs. Its long half-life allows sustained antifungal activity after oral administration. The drug's selective affinity for fungal enzymes minimizes interference with human sterol pathways leading to targeted therapeutic effect.

Fluconazole may cause nausea or stomach upset in some individuals. Headache and dizziness are also reported side effects. Skin rashes or itching can occur as an allergic reaction. Liver enzyme levels may rise, indicating possible hepatic stress. Rarely, heart rhythm abnormalities have been observed. Some patients experience taste disturbances or dry mouth. Fatigue and muscle pain are less common but documented effects.

Fluconazole is an antifungal medication that inhibits the synthesis of ergosterol in fungal cell membranes. Common side effects include headache, nausea, and abdominal discomfort. Some patients may experience dizziness or a metallic taste sensation. Rare but serious reactions can involve liver function abnormalities or severe skin rashes. The drug can interact with certain medications that affect the cytochrome p450 enzyme system. Prolonged use may lead to changes in taste perception or mild bone density reduction. Most side effects are mild and resolve without intervention.
