Ketoclenz Stay-On Lotion contains Ketoconazole 2% w/v, an imidazole antifungal agent effective against a broad spectrum of dermatophytes, yeasts, and fungi responsible for superficial skin infections. This topical formulation is indicated for the treatment of conditions such as tinea corporis, tinea cruris, tinea pedis, pityriasis versicolor, and seborrheic dermatitis. Ketoconazole exerts its antifungal action by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, leading to increased membrane permeability and ultimately fungal cell death. The lotion's stay-on formulation ensures prolonged contact with the affected area, enhancing therapeutic efficacy and patient compliance. Ketoclenz Stay-On Lotion is applied once or twice daily to the affected skin after cleansing and drying, and should be used consistently for the prescribed duration to achieve optimal results. Adverse effects are generally mild and may include local irritation, burning sensation, or erythema at the application site. Caution is advised in patients with known hypersensitivity to ketoconazole or any components of the formulation. This product is for external use only and should be kept away from eyes and mucous membranes. Consult a healthcare professional before use in pregnant or lactating women.
