Vitamin B12 is involved in methyl conversion and folic acid metabolism, promoting the conversion of 5-methyltetrahydrofolic acid into tetrahydrofolic acid. When lacking, DNA synthesis is impaired and red blood cell maturation is affected. This product also promotes the conversion of methyl malonic acid to succinic acid and participates in the tricarboxylic acid cycle. This effect is related to the synthesis of myelinated lipids and the maintenance of the functional integrity of myelinated nerve fibers, and may be related to the nerve damage in vitamin B12 deficiency. [Pharmacokinetics] Absorption is rapid and complete after intramuscular injection, and the blood concentration reaches the peak about 1 hour. The drug is widely distributed in the body, but mainly stored in the liver, with a total storage of 4-5 mg in adults. Most of them are excreted through the kidneys at 8 h. The higher the dose, the more excretion. |
