Abstract OBJECTIVE To evaluate the effects of housing environment on oral absorption of acetaminophen in dogs. ANIMALS 6 healthy Beagles. PROCEDURES Acetaminophen (325 mg, PO; mean dose, 31.1 mg/kg) was administered in a crossover study design with dogs housed in their normal environment or in a cage in an unfamiliar environment. There was a 7-day washout period between phases. Blood samples were collected for 24 hours following acetaminophen administration, and plasma acetaminophen concentrations were determined with high-pressure liquid chromatography. RESULTS A 2-compartment model with lag time was the best fit for both phases of the study. None of the primary or secondary pharmacokinetic parameters were significantly different between the 2 housing environments. CLINICAL RELEVANCE Findings suggested that in dogs, housing environment (normal environment vs a cage in an unfamiliar environment) did not significantly affect oral absorption and, by extension, gastric emptying of acetaminophen.
