Class/mechanism: Folic acid analog that is the pharmacologically active isomer of 5-formyl tetrahydrofolic acid (racemic d,l Folinic acid (Leucovorin)). Counteracts the effects of folic acid antagonists such as methotrexate, which acts by inhibiting dihydrofolate reductase. Enhances the activity of Fluorouracil (5-FU) by inhibiting thymidylate synthase.
