Description:
Mecobalamin is the neurologically active form of vitamin B12 and occurs as a water-soluble vitamin in the body. It is a cofactor in the enzyme methionine synthase, which functions to transfer methyl groups for the regeneration of methionine from homocysteine. In anemia, it increases erythrocyte production by promoting nucleic acid synthesis in the bone marrow and by promoting the maturation and division of erythrocytes.
Dosage & Administration:
Tablet: The usual adult dosage is 500 mcg tablet three times daily. The dosage should be adjusted according to the age of the patient and the severity of symptoms.
