Ketofast Shampoo is a medicated topical formulation containing Ketoconazole 2% w/v and Zinc Pyrithione 1% w/v, indicated for the treatment of dandruff, seborrheic dermatitis, and other fungal infections of the scalp. Ketoconazole, an imidazole antifungal agent, exerts its effect by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, thereby disrupting fungal growth and proliferation. Zinc Pyrithione possesses antifungal and antibacterial properties, contributing to the reduction of scalp flaking, itching, and inflammation. The combination of these active ingredients provides a broad-spectrum approach to managing scalp conditions associated with Malassezia species and other pathogens. Ketofast Shampoo is recommended for topical use on the affected scalp area, typically applied 2-3 times weekly for a duration as prescribed by a healthcare professional. It is important to massage the shampoo gently into the scalp, leave it on for several minutes to allow adequate contact time, and rinse thoroughly. Patients should avoid contact with eyes and mucous membranes. Adverse effects are generally minimal but may include mild irritation or dryness. Ketofast Shampoo should be used under medical supervision, especially in individuals with sensitive skin or pre-existing dermatological conditions.
