🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Ketoconazole works by interfering with the synthesis of ergosterol, a vital component of fungal cell membranes. It inhibits the enzyme cytochrome P450 14α-demethylase, which converts lanosterol to ergosterol. Without ergosterol, the fungal cell membrane becomes weak and leaky, leading to leakage of cellular contents and ultimately fungal cell death. This action is primarily fungistatic at lower concentrations, meaning it stops fungal growth, and can be fungicidal at higher concentrations. The 1% shampoo delivers ketoconazole directly to the scalp, where it acts locally on the Malassezia fungi that contribute to dandruff and seborrheic dermatitis.
