**Definition:** A synthetic and active form of vitamin B12 that can cross the blood brain barrier without biotransformation, that may be used to treat or prevent vitamin B12 deficiency and its complications. Upon administration, mecobalamin is able to replace endogenous vitamin B12, increase vitamin B12 levels and improve vitamin B12 deficiency. Vitamin B12 is necessary for hematopoiesis, neural metabolism, DNA and RNA production, and carbohydrate, fat, and protein metabolism. It improves iron functions in the metabolic cycle and assists folic acid in choline synthesis. Its metabolism is interconnected with that of folic acid.
