Pharmacology
Pemetrexed works by interfering with the folate-dependent processes a cell needs to copy itself. Laboratory studies show that it blocks thymidylate synthase (TS), dihydrofolate reductase, and glycinamide ribonucleotide formyltransferase (GARFT). These are folate-dependent enzymes that help the body build thymidine and purine nucleotides from scratch.
Pemetrexed gets into cells through membrane carriers, mainly the reduced folate carrier and the membrane folate binding protein transport system. Once inside, the enzyme folylpolyglutamate synthetase adds glutamate units to it, turning it into polyglutamate forms. These forms stay in the cell for a long time, and they are what keep blocking TS and GARFT.
Pregnancy & Breastfeeding
Pemetrexed can cause fetal harm when given to a pregnant woman, and no data are available on its use in this population; pregnant women should be told about this potential risk to the fetus. It is not known whether Pemetrexed or its metabolites pass into human milk, and their effects on a breastfed infant or on milk production are unknown. Because of the potential for serious adverse reactions in breastfed infants, women should not breastfeed during treatment with Pemetrexed and for one week after the last dose.
