General information

Class/mechanism: Folic acid analog; counteracts the effects of folic acid antagonists such as methotrexate, which acts by inhibiting dihydrofolate reductase. Enhances the activity of Fluorouracil (5-FU) by inhibiting thymidylate synthase.[1][2]
Route: PO, IM, IV
Extravasation: no information

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]

Diseases for which it is used

Note: these are diseases where folinic acid is used as an adjuvant to Fluorouracil (5-FU), as opposed to an antidote as it is used in conjunction with Methotrexate (MTX)
