Description :
leucovorin calcium is an active metabolite of folic acid (also called folinic acid and citrovorum factor), which does not require metabolism by dihydrofolate reductase, the molecular target of folate antagonist-type chemotherapeutic drugs. Leucovorin calcium counteracts the toxic effects of these medications, 'rescuing' the patient while permitting the antitumor activity of the folate antagonist. This agent also potentiates the effects of fluorouracil and its derivatives by stabilizing the binding of the drug's metabolite to its target enzyme, thus prolonging drug activity.

Calcium folinate/leucovorin calcium/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.
There is no apparent effect on preexisting methotrexate-induced nephrotoxicity.
