Usage
- This combination is primarily prescribed for the management of neuropathic pain, especially in conditions like diabetic neuropathy and peripheral neuropathy. It helps to alleviate symptoms such as burning, tingling, prickling, and numbness.
- Pharmacological Classification: This combination can be classified as a vitamin supplement, a metabolic agent, and an antioxidant. It addresses nerve health through multiple pathways. Benfotiamine, Folic acid, Vitamin B6, and Methylcobalamin act as vitamin supplements. Alpha-lipoic acid acts as a metabolic agent and an anti-oxidant.
- Mechanism of Action: Alpha-lipoic acid is a potent antioxidant that combats oxidative stress, a key factor in nerve damage. Benfotiamine, a lipid-soluble form of thiamine (vitamin B1), improves carbohydrate metabolism and reduces the buildup of harmful metabolites in nerve cells. Folic acid and methylcobalamin (vitamin B12) are crucial for nerve cell repair and myelination, the protective covering of nerves.
Alternate Names
- While there isn’t one single alternate name for this specific combination, the individual components are sometimes referred to by other names:
- Alpha-lipoic acid: Thioctic acid
- Methylcobalamin: Vitamin B12, cobalamin
- Folic acid: Folate, vitamin B9
- Brand Names: This combination is available under various brand names. Since brand names may be region-specific, it’s advisable to consult local pharmaceutical resources or a pharmacist for specific brands available in India.
How It Works
- Pharmacodynamics: This combination works synergistically to improve nerve function. Alpha-lipoic acid’s antioxidant activity protects nerve cells from damage. Benfotiamine enhances carbohydrate metabolism and reduces the accumulation of toxic metabolites. Folic acid and methylcobalamin support nerve cell regeneration and myelination, improving nerve conduction and reducing neuropathic pain.
- Pharmacokinetics: The individual components have different pharmacokinetic profiles. Alpha-lipoic acid is readily absorbed and metabolized in the liver. Benfotiamine is better absorbed than thiamine and converted to active thiamine in the body. Folic acid and methylcobalamin are absorbed in the gastrointestinal tract.
- Mode of Action: Benfotiamine, by increasing transketolase activity, reduces advanced glycation end products (AGEs) and protein kinase C (PKC) activation, which are implicated in diabetic complications. Alpha-lipoic acid scavenges free radicals and regenerates other antioxidants. Methylcobalamin is a cofactor for methionine synthase, essential for myelin synthesis. Folic acid participates in DNA synthesis and repair, vital for nerve cell health.
- Elimination Pathways: The components are primarily eliminated through renal and hepatic pathways.
