Mechanism[ edit ] Many are primarily DHFR inhibitors, but raltitrexed is an inhibitor of thymidylate synthase, and pemetrexed inhibits both and a third enzyme. Side-effects[ edit ] The antifolate action specifically targets the fast-dividing cells, and tend to have adverse effects on the bone marrowskinand hair.

As folate is vital in the first trimester of pregnancy for healthy fetal development, the use of antifolates is strongly contraindicated in pregnancy and carries significant teratogenic risk.

Low doses of methotrexate can deplete folate stores and cause side-effects that are similar to folate deficiency.

Both high-folate diets and supplemental folic acid may help reduce the toxic side-effects of low-dose methotrexate without decreasing its effectiveness.

Resistance[ edit ] While the role in folate as a cancer treatment is well established, its long-term effectiveness is diminished by cellular response. Because methotrexate is a competitive inhibitor of DHF reductase, increased concentrations of DHF reductase can overcome the drugs inhibition. Many new drugs are under development to reduce antifolate drug resistance.Citric acid is a naturally occurring acid which is found in large quantities in fruits – notably citrus fruits such as oranges, lemons and certain berries.

Clinical uses of folic acid

It is a relatively weak acid and has a distinct, sour taste. Introduction. Folate is a water-soluble B vitamin that is naturally present in some foods, added to others, and available as a dietary supplement.


Folic acid: Importance, deficiencies, and side effects

This topic review discusses the symptoms, clinical manifestations, and diagnosis of vitamin B12 and folate deficiency, vitamins that are required for . folic acid. Folic acid is a pteridine derived from plant sources that is structurally similar to tetrahydrobiopterin (BH4), an important cofactor for the nitric oxide synthase (NOS) enzymes.

The Vitamins page provides a detailed description of the structure and function of the water and lipid soluble vitamins and the clinical consequences of deficiencies.
