applications of folinic acid

folinic acid is administered at the appropriate time following methotrexate as part of a total chemotherapeutic plan,

where it may "rescue" bone marrow and gastrointestinal mucosa cells from methotrexate. no apparent effect is seen

on pre-existing methotrexate-induced nephrotoxicity.folinic acid can be taken as a pill (orally) or injected into a vein (intravenously) or muscle 

(intramuscularly).

 

while not specifically an antidote for methotrexate, folinic acid may also be useful in the treatment of acute methotrexate

overdose. different dosing protocols are used, but folinic acid should be redosed until the methotrexate level is less than

5 x 10−8 m.

 

additionally, folinic acid is sometimes used to reduce the side effects of methotrexate in rheumatoid arthritis patients.

this includes reductions in nausea, abdominal pain, abnormal liver blood tests, and mouth sores.

 

folinic acid is also used in combination with the chemotherapy agent 5-fluorouracil in treating colon cancer. in this case, folinic acid is not used for "rescue" purposes; rather, it enhances the 

effect of 5-fluorouracil by inhibiting thymidylate synthase.

 

folinic acid is also sometimes used to prevent toxic effects of high doses of antimicrobial dihydrofolate reductase inhibitors

such as trimethoprim and pyrimethamine. it may be prescribed in the treatment of toxoplasmosis retinitis, in combination

with the folic acid antagonists pyrimethamine and sulfadiazine.

 

folinic acid has dextro- and levorotary isomers, only the latter one being pharmacologically useful. as such, levoleucovorin

was approved by the fda in 2008.

 

it has been investigated for use in down syndrome, but a benefit has not been demonstrated.

 

research has suggested a role for folinic acid in the treatment of anxiety and depression in people with a variant of the 

mthfr gene
