🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine provides methylcobalamin, a coenzyme form of vitamin B12 that is essential for various biochemical processes. Methylcobalamin acts as a cofactor for methionine synthase, an enzyme that converts homocysteine to methionine. This reaction is crucial for DNA synthesis, methylation reactions, and myelin production. By supporting these pathways, methylcobalamin helps maintain the integrity of the nervous system and promotes normal red blood cell formation. Additionally, it enhances the regeneration of nerve cells and improves nerve conduction velocity.
