🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by supplying two essential B vitamins that play critical roles in nerve function and metabolism. Methylcobalamin is a coenzyme form of vitamin B12 that is directly involved in the methylation of homocysteine to methionine, a reaction essential for the synthesis of myelin, the protective sheath around nerves. It also supports the regeneration of damaged nerve cells. Thiamine, as thiamine pyrophosphate, is a coenzyme for several enzymes involved in carbohydrate metabolism, including pyruvate dehydrogenase and alpha-ketoglutarate dehydrogenase, which are vital for energy production in nerve cells. By correcting deficiencies, this medicine helps restore normal nerve function and alleviates neurological symptoms.
