Fluconazole, also known by the brand name Diflucan, is an antifungal medication belonging to the azole class. It is primarily used to treat a variety of fungal infections throughout the body, including vaginal yeast infections, oral thrush (candidiasis of the mouth and throat), esophageal candidiasis, urinary tract infections, and serious systemic fungal infections like cryptococcal meningitis. Fluconazole is effective against specific types of fungi, particularly Candida species. It works by interfering with the synthesis of ergosterol, a vital component of fungal cell membranes. This disruption leads to increased permeability of the fungal cell membrane, ultimately inhibiting fungal growth and replication.
Fluconazole is available in oral tablet, oral suspension, and intravenous forms. The specific formulation and dosage depend on the type and severity of the infection, as well as individual patient factors. It is generally well-absorbed after oral administration and distributes widely throughout the body, including into the cerebrospinal fluid, which makes it useful for treating fungal infections of the brain and spinal cord (per the NIH ODS Fluconazole Monograph).
