Pharmacology: Mecobalamin which biochemically is a Vitamin B12 containing co-enzyme with an active methyl base. Mecobalamin participates in transmethylation reactions and is the most active of all B12 homologs in the body with respect to nucleic acid, protein and lipid metabolism. Mecobalamin acts to repair damaged nerve tissue in nerve disorders, such as axonal degeneration and demyelination; and it is involved in erythroblast maturation, promotion of erythroblast division and heme synthesis, thus acting to improve the status of the blood in megaloblastic anemia.
