5. Pharmacological Properties

5.1 Pharmacodynamic Properties.

Pharmacotherapeutic group: Preparations for oral B 12 therapy, ATC code: B03BA01 Vitamin B12 is essential in humans and active in mainly two important enzyme systems. The adenosylated form is the cofactor of the mitochondrial enzyme methylmalonyl CoA-mutas.

This reaction is important for normal fatty acid metabolism. The methylated form of vitamin B12 cofactor of methionine synthetase and thus essential for normal cell division.

Lack of methylcobalamin is also considered to be behind the demyelination seen in vitamin B12 deficiency. A disorder in this system leads to abnormal DNA metabolism with symptoms of primary organs with rapid cell division like bone marrow and mucosa. Experimentally, it has been shown that a lack of the methylating form is accompanied by neurological damage.

5.2 Pharmacokinetic Properties

After absorption from the sublingual mucosa:

Vitamin B12 is extensively bound to specific plasma proteins called transcobalamin, transcobalamin 2 appears to be involved in the rapid transport of the cobalamin to tissue.

Vitamin B12 is stored in the liver, excreted in the bile, and undergoes extensive enterohepatic recycling: part of the dose excreted in the urine, most of it in the first 8 hours; urinary excretion, however, accounts for only a small fraction in the reduction of total body stores acquired by dietary means. Vitamin B12 across the placenta and also appears in breast milk.
