🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by supplying two essential B vitamins that are crucial for normal nerve function and energy metabolism. Methylcobalamin acts as a coenzyme for methionine synthase, which is involved in the synthesis of methionine and tetrahydrofolate, essential for DNA synthesis and myelin formation. It also supports the regeneration of damaged nerve cells. Thiamine, after conversion to thiamine pyrophosphate, serves as a cofactor for several enzymes in carbohydrate metabolism, including pyruvate dehydrogenase and transketolase. This helps in the production of ATP and maintains the health of the nervous system and heart.
