Lenitine 1gm Injection contains Levo-carnitine, a naturally occurring amino acid derivative essential for the transport of long-chain fatty acids into the mitochondria for energy production. This injectable formulation is indicated for the treatment of primary and secondary carnitine deficiency, which may arise due to inherited metabolic disorders, chronic renal failure, or specific drug therapies that impair carnitine metabolism. Lenitine facilitates the oxidation of fatty acids, thereby improving cellular energy metabolism and reducing the accumulation of toxic organic acids. It is commonly used in clinical settings to manage conditions such as carnitine deficiency in hemodialysis patients, certain inborn errors of metabolism, and as an adjunct in the treatment of myocardial ischemia and peripheral vascular disease. The administration of Lenitine 1gm Injection should be performed under medical supervision, with dosage tailored according to the patient’s clinical condition and response. Adverse effects are generally mild but may include gastrointestinal disturbances, injection site reactions, or rare hypersensitivity responses. Caution is advised in patients with hypersensitivity to Levo-carnitine or any excipients. Lenitine 1gm Injection is a valuable therapeutic agent in restoring normal carnitine levels and enhancing metabolic function in affected individuals.
