Brand Name : FOLATE
Generic Name : Folic acid
Preparation : 5 mg Tablet
Pharmacological Categories : Water Soluble Vitamin (Vitamin B9), Erythropoiesis Agent
Mechanism of Action (MOA)
FOLATE (Folic acid) is reduced to tetrahydrofolate in the body, which is a coenzyme for various metabolic processes including the synthesis of purine and pyrimidine nucleotides, and hence in the synthesis of DNA, for maintenance of erythropoiesis. FOLATE also stimulates WBC, platelet production in folate deficiency anemia.

- Oral contraceptive, antituberculous drugs, alcohol, methotrexate, pyrimethamine, traimterene, carbamazepine, chloramphenicol, trimethoprim and sulfonamide decreases folic acid level.
- Pancrelipase decreases level of folic acid by inhibition of gastrointestinal absorption.
- Aspirin decreases level of folic acid by inhibition of gastrointestinal absorption.
- Folic acid decreases level of phenytoin, phenobarbital by increasing metabolism.
- Sulfasalazine decreases level of folic acid by inhibition of gastrointestinal absorption.
- Metformin decreases level of folic acid by unspecified interaction mechanism.
- Frusemide, hydrochlorothiazide decreases level of folic acid by increasing renal clearance.
