About
Ketoconazole is an imidazole antifungal agent widely utilized for the treatment of various fungal infections, both superficial and systemic. Its mechanism of action involves inhibiting the synthesis of ergosterol, a crucial component of fungal cell membranes. This disruption leads to increased membrane permeability, leakage of essential cellular contents, and ultimately, the death of the fungal cell. It demonstrates efficacy against a broad spectrum of fungi, including dermatophytes, yeasts, and other pathogenic species. While topical formulations are commonly employed for localized infections, systemic use of ketoconazole is generally reserved for severe or refractory fungal infections due to its potential for significant hepatotoxicity and numerous drug interactions. Careful patient selection and monitoring are essential when considering systemic therapy.
