Usage
- This combination medication is primarily prescribed for supporting liver health and function, particularly in conditions like:
- Acute and chronic hepatitis
- Chronic alcoholic liver damage
- Fatty liver (hepatic steatosis)
- Jaundice
- Liver cirrhosis
- Non-alcoholic steatohepatitis (NASH)
- Pharmacological Classification: Hepatoprotective, Anti-oxidant, Ammonia-lowering agent.
- Mechanism of Action: This combination works synergistically to protect and regenerate the liver. L-ornithine L-aspartate reduces elevated ammonia levels, metadoxine acts as an antioxidant and improves liver function by increasing the desaturase enzyme, restoring ATP synthesis, and improving redox balance. Silymarin protects the liver from free radical damage and enhances glutathione and protein synthesis, which helps in the production of new liver cells. Vitamin B6 supports various metabolic processes, including protein metabolism and enzyme activity, that are important for liver function.
Alternate Names
- No widely recognized alternate names exist for this specific four-ingredient combination. However, each individual component has its own synonyms.
- Brand Names: A few brand names for products containing this combination, or a close variation, are:
- Liviz
- Reheptin
- B Liv
- Livopill DS (with added folic acid)
There may be other regional or international brand names.
How It Works
- Pharmacodynamics:
- L-Ornithine L-Aspartate: Reduces elevated blood ammonia levels by participating in the urea cycle, where ammonia is converted into urea for excretion. This is crucial in managing hepatic encephalopathy.
- Metadoxine: Improves the balance of saturated and unsaturated fatty acids in the liver, promoting healthy liver function. Additionally, it aids in the detoxification of alcohol and acetaldehyde.
- Silymarin: Protects liver cells by acting as an antioxidant. It also supports liver regeneration by stimulating protein synthesis.
- Vitamin B6 (Pyridoxine): A crucial cofactor for various enzymes involved in liver metabolism, it contributes to overall liver health.
- Pharmacokinetics:
- Absorption: Orally administered, with absorption profiles varying slightly for each component.
- Metabolism: Each component undergoes hepatic metabolism via different pathways, although specific details might vary depending on the formulation.
- Elimination: Primarily renal excretion, although some biliary excretion may occur.
- Mode of Action:
- L-Ornithine L-Aspartate increases the synthesis of glutamine, lowering the concentration of ammonia, a toxic byproduct of protein metabolism.
- Metadoxine acts by enhancing the desaturase enzyme activity, restoring ATP synthesis, and improving redox balance of hepatocytes.
- Silymarin prevents hepatic lipid peroxidation, increasing glutathione and protein synthesis.
- Vitamin B6 serves as a cofactor for enzymatic activities necessary for proper liver function.
- Receptor binding, enzyme inhibition, or neurotransmitter modulation: L-ornithine L-aspartate influences urea cycle enzymes, while metadoxine interacts with enzymes involved in alcohol metabolism. Silymarin interacts with cell membranes and intracellular pathways, while Vitamin B6 modulates enzymatic reactions.
Dosage
It’s crucial to note that dosage information provided here is generalized and may not reflect the specific recommendations for all available formulations. Always consult the latest prescribing information relevant to the specific product being used.
Standard Dosage
Adults:
- One tablet two to three times a day, typically taken after meals. Some formulations might suggest different dosages or frequencies. Dosage adjustments may be required in patients with renal or hepatic impairments.
- Specific dosages of individual components can vary across different brands. One common combination includes: Metadoxine 250mg, Silymarin 70mg, L-Ornithine L-Aspartate 75mg and Vitamin B6 3mg. Another includes Metadoxine 500mg, Silymarin 140mg, L-Ornithine L-Aspartate 150mg, Vitamin B6 3mg, and Folic Acid 1.5mg.
Children:
- Dosage in children should be determined by a pediatrician based on weight or age and clinical condition. The medication is usually not recommended for children unless specifically prescribed.
Special Cases:
- Elderly Patients: Start with a lower dose and monitor for adverse events. Dosage may be titrated upward as needed and tolerated.
- Patients with Renal Impairment: Dose reduction is often necessary depending on the degree of impairment. Close monitoring of renal function is advisable.
- Patients with Hepatic Dysfunction: Careful monitoring of liver function tests is necessary, and dosage adjustments might be required based on the severity of dysfunction.
- Patients with Comorbid Conditions: Consider potential interactions and adjust dosages as needed, especially in those with diabetes, cardiovascular disease, or neurological conditions.
Clinical Use Cases
- Dosage in specific clinical settings like intubation, surgical procedures, mechanical ventilation, ICU use, or emergency situations must be determined by the treating physician considering patient-specific factors and guidelines. General dosing recommendations as mentioned above may serve as a baseline.
Dosage Adjustments
- Adjust dosages based on renal/hepatic function, concurrent medications, and patient response. Therapeutic drug monitoring may be necessary in certain cases.
