How Does It Work?
Itraconazole is a highly selective inhibitor of fungal cytochrome P-450-dependent enzyme, thereby decreasing ergosterol biosynthesis and inhibits the formation of fungal cell membranes. Ergosterol is a significant component of the fungal cell membrane; inhibition of its synthesis leads to increased cellular permeability, thereby causing leakage of cellular contents.
Itraconazole is used to treat the following conditions:
- Esophageal candidiasis
- Oral candidiasis
- Prophylaxis of fungal infections in immunocompromised patients
- Oropharyngeal candidiasis
- Vulvovaginal candidiasis
- Pityriasis Versicolor
- Tinea corporis
- Tinea cruris
- Nail fungal infections
- Systemic fungal infections
- Prophylaxis of infections in neutropenic or AIDS patients
