Synthetic antifungal agents such as Clotrimazole, Miconazole, Ketoconazole, Itraconazole and Fluconazole form the cornerstone of antifungal therapy in both topical and systemic infections. These azoles (imidazoles and triazoles) act primarily by inhibiting lanosterol 14α‑demethylase, disrupting ergosterol synthesis and fungal membrane integrity. Key B.Pharm concepts include mechanism of action, spectrum of activity, pharmacokinetics, CYP450 drug interactions, … Read more

Antifungal antibiotics — Amphotericin B, Nystatin, Natamycin, Griseofulvin — are essential in B. Pharm curricula for understanding antifungal pharmacology, mechanisms, spectrum, formulations and adverse effects. Amphotericin B disrupts fungal membranes by binding ergosterol; lipid formulations reduce nephrotoxicity. Nystatin and Natamycin target ergosterol too, but are used mainly as topical or ophthalmic agents. Griseofulvin interferes with … Read more
