🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by inhibiting the synthesis of ergosterol, a vital component of the fungal cell membrane. Ketoconazole, the active ingredient, binds to and inhibits the enzyme cytochrome P450 14α-demethylase. This inhibition blocks the conversion of lanosterol to ergosterol, leading to a weakened and permeable cell membrane. As a result, essential cellular components leak out, and the fungus cannot survive. Additionally, ketoconazole may have some anti-inflammatory effects that help reduce scalp irritation and redness. This dual action makes it effective against Malassezia yeasts and other fungi.
