Glucarpidase (Voraxaze), previously known as carboxypeptidase G2, is a carboxypeptidase G2 enzyme that hydrolyses the terminal glutamate residue from methotrexate.2 Glucarpidase hydrolyses methotrexate rapidly to the inactive metabolites DAMPA (4-[[2,4-diamino-6-(pteridinyl)methyl]-methylamino]-benzoic acid) and glutamate in patients with methotrexate-induced nephrotoxicity and delayed methotrexate excretion.3 It has been shown that the conversion of methotrexate to DAMPA relieves stress on the kidneys for elimination of methotrexate, by providing an alternative route of elimination, and generates a relatively nontoxic compound.4
Glucarpidase for methotrexate toxicity
Glucarpidase (Voraxaze), previously known as carboxypeptidase G2, is a carboxypeptidase G2 enzyme that hydrolyses the terminal glutamate residue from methotrexate. Glucarpidase hydrolyses methotrexate rapidly to the inactive metabolites DAMPA (4-[[2,4-diamino-6-(pteridinyl)methyl]-methylamino]-benzoic acid) and glutamate in patients with methotrexate-induced nephrotoxicity and delayed methotrexate excretion.
