Ketonol 2% Ketoconazole Anti Dandruff Shampoo is a medicated topical formulation containing 2% w/v ketoconazole, an imidazole antifungal agent effective in the treatment of dandruff and seborrheic dermatitis of the scalp. Ketoconazole exerts its therapeutic action by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, thereby disrupting fungal growth and proliferation. This shampoo is indicated for patients experiencing flaking, scaling, itching, and redness associated with dandruff and seborrheic dermatitis caused by Malassezia species. Ketonol 2% Ketoconazole Shampoo is designed for topical application to the scalp; it should be applied to wet hair, massaged gently into the scalp to form a lather, left on for 3 to 5 minutes to allow adequate antifungal activity, and then rinsed thoroughly. Regular use, typically twice weekly for 2 to 4 weeks, is recommended to achieve optimal results, followed by maintenance therapy as advised by a healthcare professional. The product is generally well tolerated, with minimal adverse effects such as mild scalp irritation or dryness. It is contraindicated in individuals with hypersensitivity to ketoconazole or any shampoo excipients. Consultation with a healthcare provider is advised before use, especially in pregnant or breastfeeding women.
