CompositionFolic Acid (5 mg)
SALT INFORMATIONFolic Acid (5 mg) TYPICAL USAGE Folate-deficient. Megaloblastic anaemia. Prophylaxis of megaloblastic anemia in pregnancy. Prophylaxis of neural tube defect in pregnancy. Malabsorption syndromes. Antiepileptic therapy. SIDE EFFECTS Neuropathy, bronchospasm, itchy skin eruptions, malaise. DRUG INTERACTION Interacts with other drugs like deferoxamine, epoetin, fosphenytoin, methotrexate, sulphasalazine. These interactions are sometimes beneficial and sometimes may pose threats to life. Always consult your physician for the change of dose regimen or an alternative drug of choice that may strictly be required. MECHANISM OF ACTION Folic acid, as it is biochemically inactive, is converted to tetrahydrofolic acid and methyltetrahydrofolate by dihydrofolate reductase. These folic acid congeners are transported across cells by receptor-mediated endocytosis where they are needed to maintain normal erythropoiesis, synthesize purine and thymidylate nucleic acids, interconvert amino acids, methylate tRNA, and generate and use formate. Using vitamin B12 as a cofactor, folic acid can normalize high homocysteine levels by remethylation of homocysteine to methionine via methionine synthetase.
