Usage
- Levo-carnitine + Vitamin E is primarily used as a nutritional supplement to support energy production, enhance fat metabolism, and promote overall well-being. It may also be used to address carnitine deficiency. It is being investigated for use in patients on dialysis as part of a study.
- Pharmacological classification: Nutritional supplement, metabolic agent, antioxidant.
- Mechanism of action: Levo-carnitine facilitates the transport of long-chain fatty acids into the mitochondria for beta-oxidation and energy production. Vitamin E acts as an antioxidant, protecting cells from oxidative stress.
Alternate Names
- L-carnitine + Vitamin E
- Levocarnitine and Vitamin E combination
How It Works
- Pharmacodynamics: Levo-carnitine enhances fatty acid oxidation, improving energy production. Vitamin E scavenges free radicals, protecting cell membranes and other structures from oxidative damage.
- Pharmacokinetics: Levo-carnitine is absorbed in the small intestine and distributed throughout the body. It is primarily eliminated renally. Vitamin E is absorbed with dietary fats and distributed to tissues. It is metabolized in the liver and excreted in bile.
- Mode of action: Levo-carnitine acts as a carrier molecule, transporting fatty acids across the mitochondrial membrane. Vitamin E donates electrons to neutralize free radicals, preventing lipid peroxidation.
- Elimination pathways: Levo-carnitine: Renal excretion. Vitamin E: Hepatic metabolism and biliary excretion.
Dosage
Standard Dosage
Adults:
- Oral: One capsule containing 100 mg levocarnitine and 200 mg vitamin E, once daily, or as directed by a healthcare professional. Other sources suggest 990 mg of levocarnitine two or three times a day.
- One study on dialysis patients used 500 mg levocarnitine daily.
Children:
- The dosage for children needs to be determined by a doctor based on the child’s weight and the specific condition being treated.
Special Cases:
- Elderly Patients: Dosage adjustments may be needed based on kidney function.
- Patients with Renal Impairment: Dose reduction might be necessary.
- Patients with Hepatic Dysfunction: Caution is advised; dosage adjustments may be needed.
- Patients with Comorbid Conditions: Dose adjustments should be made under medical supervision.
