Kentruff Stay On Lotion contains Ketoconazole 2% w/v, an antifungal agent effective in the treatment of various fungal infections of the skin. Ketoconazole belongs to the imidazole class of antifungals and works by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, thereby disrupting membrane integrity and leading to fungal cell death. This lotion is primarily indicated for the management of dandruff and seborrheic dermatitis, conditions commonly associated with the proliferation of Malassezia species on the scalp. Kentruff Stay On Lotion is formulated for topical application and provides targeted antifungal activity with minimal systemic absorption. It is suitable for adults and adolescents and should be applied to the affected area once or twice daily as directed by a healthcare professional. Adverse effects are generally mild and may include local irritation, itching, or redness at the site of application. Patients with known hypersensitivity to ketoconazole or any component of the formulation should avoid use. This product should be used with caution in individuals with broken or inflamed skin. Consistent use as prescribed is essential for optimal therapeutic outcomes and to prevent recurrence of fungal infections.
