Diflucan (Fluconazole 150mg) 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. Diflucan is commonly prescribed to treat various fungal infections, including vaginal yeast infections, oral thrush, esophageal candidiasis, and cryptococcal meningitis. It is also used for the prevention of candidiasis in patients undergoing bone marrow transplantation. Diflucan has shown efficacy in treating fungal infections and preventing their recurrence.
