What is Glucarpidase and explain in detail?
Glucarpidase (Voraxaze) is a medication used for the treatment of elevated levels of methotrexate (defined as 1 micromol/L) during treatment of cancer patients who have impaired kidney function (and thus cannot reduce the drug to safe levels sufficiently after the drug has been given). Glucarpidase is an enzyme that inactivates methotrexate rapidly after injection. Because this agent reduces systemic levels of methotrexate and could therefore interfere with efficacy, it is not recommended for use in patients with normal or only slightly impaired kidney function or in whom serum levels are normal
