🧴🦠💆‍♂️ Ketoconazole 2%: Powerful Antifungal Treatment for Skin & Scalp Infections

Ketoconazole 2% is a broad-spectrum antifungal medication widely used in topical form (cream, shampoo, lotion) to treat fungal and yeast infections affecting the skin and scalp. Belonging to the class of imidazole antifungals, Ketoconazole works by disrupting the fungal cell membrane, ultimately killing the fungus or stopping its growth.

This concentration (2%) is particularly effective for seborrheic dermatitis, dandruff, tinea (ringworm) infections, and cutaneous candidiasis, making it a commonly prescribed option in dermatology.

🔬 Mechanism of Action

Ketoconazole inhibits the synthesis of ergosterol, a key component of fungal cell membranes. Without ergosterol, the membrane becomes weak and leaky, causing cell contents to spill out, leading to fungal death or inhibition of growth.

It is fungistatic (stops fungal growth) in lower concentrations and fungicidal (kills fungi) in higher concentrations like 2%.
