Ketomac Shampoo contains Ketoconazole 2% w/v, an antifungal agent indicated for the treatment of dandruff and seborrheic dermatitis of the scalp. Ketoconazole is an imidazole derivative that exerts its effect by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, thereby disrupting fungal growth and replication. This shampoo is effective against Malassezia species, which are commonly implicated in dandruff and seborrheic dermatitis. Ketomac Shampoo is applied topically to the affected scalp area, typically used twice weekly for a duration determined by clinical response, usually ranging from 2 to 4 weeks. It helps reduce scaling, itching, and inflammation associated with fungal infections of the scalp. The formulation is generally well-tolerated; however, mild local adverse reactions such as irritation, burning sensation, or dryness may occur. It is contraindicated in individuals with known hypersensitivity to Ketoconazole or any components of the formulation. Caution is advised to avoid contact with eyes and mucous membranes. Ketomac Shampoo should be used as directed by a healthcare professional, and patients should be advised to complete the full course of treatment to prevent recurrence. This product is not intended for systemic fungal infections and should not be ingested.
