Fluconazole 150 mg tablets are a widely used antifungal medication that is effective in treating various types of fungal infections. As a triazole derivative, fluconazole works by inhibiting the synthesis of ergosterol, a critical component of fungal cell membranes, ultimately leading to the death of the fungal cells. This medication is commonly prescribed for the treatment of vaginal yeast infections, oral thrush, and other fungal infections.
The fluconazole 150 mg tablet is a single-dose treatment for uncomplicated vulvovaginal candidiasis, making it a convenient option for patients. The tablet is usually taken orally, and its absorption is not affected by food, allowing for flexible dosing. The medication is available in various formulations, including tablets, injections, and oral suspensions, making it accessible for different patient needs.
Primary Uses of Fluconazole 150 Mg Tablets
Fluconazole 150 mg tablets are primarily used for the treatment of:
- Vulvovaginal candidiasis (vaginal yeast infections)
- Oral thrush (oropharyngeal candidiasis)
- Esophageal candidiasis (fungal infection of the esophagus)
- Cryptococcal meningitis (fungal infection of the brain and spinal cord)
- Other fungal infections, including those caused by Candida and Cryptococcus species
Mechanism of Action
Fluconazole exerts its antifungal effects by inhibiting the enzyme lanosterol 14α-demethylase, which is essential for the conversion of lanosterol to ergosterol in fungal cells. Ergosterol is a critical component of fungal cell membranes, and its depletion leads to increased cell membrane permeability, ultimately resulting in fungal cell death.
