PRESCRIPTION DRUG
Levocarnitine is indicated in the treatment of primary systemic carnitine deficiency. In the reported cases, the clinical presentation consisted of recurrent episodes of Reye-like encephalopathy, hypoketotic hypoglycemia, and/or cardiomyopathy. Associated symptoms included hypotonia, muscle weakness and failure to thrive. A diagnosis of primary carnitine deficiency requires that serum, red cell and/or tissue carnitine levels be low and that the patient does not have a primary defect in fatty acid or organic acid oxidation (see Clinical Pharmacology ). In some patients, particularly those presenting with cardiomyopathy, carnitine supplementation rapidly alleviated signs and symptoms. Treatment should include, in addition to carnitine, supportive and other therapy as indicated by the condition of the patient. Levocarnitine is also indicated for acute and chronic treatment of patients with an inborn error of metabolism which results in a secondary carnitine deficiency. None known.
Levocarnitine Oral Solution is supplied in 118 mL (4 FL. OZ.) multiple-unit plastic containers. The multiple-unit containers are packaged 24 per case (NDC 50383-171-04). Store at controlled room temperature (25°C). See USP. Levocarnitine Oral Solution, USP is distributed by Akorn Operating Company LLC, Gurnee, IL 60031. Rx only.
New Drug Application
LEVOCARNITINE- LEVOCARNITINE SOLUTION AKORN ---------- LEVOCARNITINE ORAL SOLUTION, USP (1 G PER 10 ML MULTIDOSE) FOR ORAL USE ONLY. NOT FOR PARENTERAL USE. DESCRIPTION Levocarnitine is a carrier molecule in the transport of long-chain fatty acids across the inner mitochondrial membrane. The chemical name of levocarnitine is 3-carboxy-2(_R_)-hydroxy-N,N,N-trimethyl-1- propanaminium, inner salt. Levocarnitine is a white crystalline, hygroscopic powder. It is readily soluble in water, hot alcohol, and insoluble in acetone. The specific rotation of levocarnitine is between -29° and -32°. Its chemical structure is: Each 118 mL container of Levocarnitine Oral Solution contains 1 g of levocarnitine/10 mL. Also contains: Artificial Cherry Flavor, D,L,-Malic Acid, Purified Water, Sucrose Syrup. Methylparaben NF and Propylparaben NF are added as preservatives. The pH is approximately 5. CLINICAL PHARMACOLOGY Levocarnitine is a naturally occurring substance required in mammalian energy metabolism. It has been shown to facilitate long-chain fatty acid entry into cellular mitochondria, thereby delivering substrate for oxidation and subsequent energy production. Fatty acids are utilized as an energy substrate in all tissues except the brain. In skeletal and cardiac muscle, fatty acids are the main substrate for energy production. Primary systemic carnitine deficiency is characterized by low concentrations of levocarnitine in plasma, RBC, and/or tissues. It has not been possible to determine which symptoms are due to carnitine deficiency and which are due to an underlying organic acidemia, as symptoms of both abnormalities may be expected to improve with levocarnitine. The literature reports that carnitine can promote the excretion of excess organic or fatty acids in patients with defects in fatty acid metabolism and/or specific Empirical Formula: C H NO 7 15 3 Molecular Weight: 161.20 1-6 organic acidopathies that bioaccumulate acylCoA esters.
