Ketonext AF Lotion contains Ketoconazole 2% w/v, an antifungal agent effective against a broad spectrum of dermatophytes, yeasts, and fungi responsible for superficial fungal infections. Ketoconazole acts by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, leading to increased membrane permeability and ultimately fungal cell death. This lotion is indicated for the treatment of various fungal skin infections including tinea corporis, tinea cruris, tinea pedis, and pityriasis versicolor. It is also effective in managing seborrheic dermatitis due to its antifungal and anti-inflammatory properties. Ketonext AF Lotion is intended for topical use and should be applied to the affected area once or twice daily as prescribed, ensuring the skin is clean and dry before application. Treatment duration typically ranges from 2 to 4 weeks depending on the severity and type of infection. Common adverse effects are generally mild and may include local irritation, itching, or redness at the application site. Patients should avoid contact with eyes and mucous membranes. If irritation persists or worsens, medical advice should be sought. Ketonext AF Lotion should be stored at room temperature, away from direct sunlight and out of reach of children.
