What is Dietary Composition Alters Methotrexate Toxicity Without Changing Its Pharmacokinetic Parameters in Cats about?

This study determined the effect of a commercial dry expanded (complex) diet and purified diet on methotrexate (MTX) toxicity and pharmacokinetics in the cat. Twelve cats were randomized to receive a purified diet or a complex diet for 21 days. They were then given an intravenous bolus injection of MTX at a dose of 10 mglkg (160 mglM2). Cats fed the purified diet had severe enteritis, characterized by depression, lethargy, diarrhea, and vomiting. Cats receiving the complex diet remained mentally bright, alert, and responsive throughout the post-chemotherapy period, and only one of six cats in this dietary group developed mild diarrhea 48 hr after MTX administration. Methotrexate was associated with a significant (P < 0.0001) reduction in the total white blood cell (WBC) counts in cats receiving the purified and complex diets. The elimination of MTX appeared to follow a three-compartment model of elimination. Plasma MTX concentrations at all time points examined were virtually identical in cats receiving the purified and complex diets. The terminal half-life of MTX in cats receiving the complex and purified diets was I .75 f 0.44 hr and 2.77 f 0.8 hr, respectively. The similarity of
