Spectrum Pharmaceuticals, Inc.

Drug Names(s): LFA, Levofolinic Acid, Isovorin, ISO-Vorin, LEVOleucovorin

Description: Levofolinic acid is a pure active isomer of Leucovorin (folinic acid). Leucovorin calcium (folinic acid) is a reduced form of folic acid. Folic acid participates in several key biological processes, including the synthesis of DNA, RNA and proteins. It is necessary for DNA replication and repair, the maintenance of the integrity of the genome, and is involved in the regulation of gene expression, among other things.

Leucovorin is usually used 24 hours aftermethotrexate to selectively “rescue” normal cells from the adverse effects of methotrexatecaused by inhibition of production of reduced folates. It is not used simultaneously withmethotrexate, as it might then nullify the therapeutic effect of the methotrexate. More recently,leucovorin has also been used to enhance the activity of fluorouracil by binding to the enzymethymidylate synthetase and decreasing intracellular levels of thymidylate. Commerciallyavailable leucovorin is the racemic mixture of D and L isomers; the L stereoisomer is the activemoiety.
