title: Methotrexate megadose followed by folate rescue. II. Clearance patterns in patients receiving sequential megadose infusions.
abstract: In some patients receiving megadose infusions of methotrexate (MTX), the rate of drug clearance decreases with each subsequent infusion. This can be modified by administration of fluids as outlined in the Recommended Protocol. Monitoring of each treatment is needed to assess requirements of fluids since these cannot be adequately predicted from data of previous infusions.
