General information
Class/mechanism: Folate analog, antimetabolite, interferes with DNA synthesis. Methotrexate inhibits dihydrofolic acid reductase, which catalyzes reactions that produce tetrahydrofolates, which are used in purine nucleotide and thymidylate synthesis.[1][2][3][4][5][6][7]
Route: IV, PO, IM, IT, SC, intraarterial
Extravasation: inflammitant
- Glucarpidase (Voraxaze) can be used to treat toxic plasma methotrexate concentrations (greater than 1 micromole per liter) in patients with delayed methotrexate clearance due to impaired renal function
For conciseness and simplicity, HemOnc.org currently will focus on treatment regimens and not list information such as: renal/hepatic dose adjustments, metabolism (including CYP450), excretion, monitoring parameters (although this will be considered for checklists), or manufacturer. Instead, for the most current information, please refer to your preferred pharmacopeias such as Micromedex, Lexicomp, UpToDate (courtesy of Lexicomp), or the prescribing information.[1]
