Fluconazole is an antifungal medication classified as a triazole. It works by inhibiting the synthesis of ergosterol, a key component of fungal cell membranes, leading to cell membrane disruption and fungal cell death. Fluconazole is commonly used to treat various fungal infections, including vaginal yeast infections, oral thrush, esophageal candidiasis, and cryptococcal meningitis. It is also effective in preventing fungal infections in patients with weakened immune systems due to conditions such as HIV/AIDS or cancer. Fluconazole demonstrates high efficacy in treating fungal infections and is well-tolerated by most patients.
