The relatively insoluble drug, acetaminophen, administered as a solution and injected intraperitoneally in rats, has been shown to produce an antipyretic response. approximately twice that of the same dose administered as a suspension. This experiment indicates that EDw, LDw, and relative potency ca

โฆ Synopsis
An animal model used yeast-fevered rats to measure the relative antipyretic effects of different commercially available acetaminophen-containing suppositories. A laboratory-prepared acetaminophen-containing suppository and placebo suppositories also were investigated. Release from the suppositories was measured in vitro. All acetaminophen products containing 600 mg of drug elicited significant decreases in the rectal temperature of fever-induced rats.

Four commercial aspirin formulations and aspirin powder USP were assayed in yeast-fevered rats for antipyretic activity. Tablets allowed to disintegrate spontaneously prior to dosing yielded aggregates of various sizes which failed to produce uniform patterns of antipyresis. When tested at smaller,
Fever was induced in rats with a single i.p. injection of 30 g/kg E. coli endotoxin. The effect of the alcohol leaf extract of Azadirachta indica was investigated in this model. Pretreatment of rats with the leaf extract (125-375 mg/kg) did not significantly reduce endotoxin-induced fever. The recta
