Lacarnit Injection contains Levo-carnitine 1gm per 5ml and is indicated for the treatment of carnitine deficiency states. Levo-carnitine is a naturally occurring amino acid derivative essential for the transport of long-chain fatty acids into the mitochondria for beta-oxidation and energy production. This injection is primarily used in conditions associated with primary or secondary carnitine deficiency, including inherited metabolic disorders, chronic renal failure, and certain cardiomyopathies. Lacarnit Injection facilitates improved energy metabolism and has a role in enhancing cardiac and skeletal muscle function. It may also be employed as adjunctive therapy in patients undergoing hemodialysis or peritoneal dialysis to correct carnitine depletion. The administration of Lacarnit Injection should be performed under medical supervision, with dosage individualized based on the patient’s clinical condition and response. Common adverse effects are generally mild and may include gastrointestinal disturbances or injection site reactions. Caution is advised in patients with hypersensitivity to Levo-carnitine or any component of the formulation. Lacarnit Injection should be stored according to manufacturer guidelines to maintain stability and efficacy. It is contraindicated in patients with known hypersensitivity to the active substance.
