Ketonet Tablet contains Ketoconazole 200 mg, an antifungal agent belonging to the imidazole class, indicated for the treatment of various fungal infections. It exerts its therapeutic effect by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, thereby disrupting membrane integrity and leading to fungal cell death. Ketonet is primarily prescribed for systemic and superficial mycoses, including dermatophytosis, candidiasis, and seborrheic dermatitis. The tablet is administered orally, with dosage and duration tailored according to the severity and type of infection, as well as patient response. It is important to use Ketonet under medical supervision due to potential adverse effects such as hepatotoxicity, gastrointestinal disturbances, and rare allergic reactions. Liver function tests should be monitored periodically during prolonged therapy. Ketonet is contraindicated in patients with known hypersensitivity to ketoconazole or other azole antifungals, and caution is advised in individuals with pre-existing liver disease. Drug interactions may occur with agents metabolized by the cytochrome P450 system; therefore, a thorough review of concomitant medications is essential before initiating therapy. Ketonet Tablet offers an effective option for managing fungal infections when used appropriately and with adherence to prescribed guidelines.
