Vitamin B12 tablets
Function and Efficacy
This product is an anti-anemia drug. Vitamin B12 participates in methyl conversion and folic acid metabolism in the body, and promotes the conversion of 5-methyltetrahydrofolate into tetrahydrofolate. When it is deficient, it leads to DNA synthesis disorders and affects the maturation of red blood cells. This product also promotes the conversion of methylmalonic acid into succinic acid and participates in the tricarboxylic acid cycle. This effect is related to the synthesis of nerve myelin lipids and the maintenance of the integrity of myelinated nerve fiber function. The nerve damage caused by vitamin B12 deficiency may be related to this.

Drug Interactions
1. Avoid using it in combination with chloramphenicol, otherwise it may counteract the hematopoietic function of vitamin B12. 2. In vitro experiments have found that vitamin C can destroy vitamin B12. When vitamin C is administered at the same time or taken in large quantities for a long time, the blood concentration of vitamin B12 may decrease. 3. Aminoglycoside antibiotics, para-aminosalicylic acid, phenobarbital, phenytoin sodium, primidone and other anticonvulsants and colchicine can reduce the absorption of vitamin B12 from the intestine. 4. Cholestyramine can bind to vitamin B12 and reduce its absorption.
