🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Methylcobalamin is a coenzyme form of vitamin B12. It is required for two important enzymatic reactions in the body: the conversion of homocysteine to methionine (via methionine synthase) and the conversion of methylmalonyl-CoA to succinyl-CoA (via methylmalonyl-CoA mutase). These reactions are essential for normal DNA synthesis, red blood cell formation, and maintenance of the myelin sheath that surrounds and protects nerves. In vitamin B12 deficiency, these reactions are impaired, leading to megaloblastic anemia and neurological damage. By supplying methylcobalamin, the injection restores these enzymatic functions, allowing normal blood cell production and nerve function to resume.
