title: Blood sampling site-dependent plasma concentrations and hepatotoxic parameters in serum after intraperitoneal administration of acetaminophen to rats.
abstract: Blood sampling site-dependent (the dorsal aorta, the jugular vein, and the retro-orbital sinus) plasma concentrations of acetaminophen and its glucuronide and sulfate conjugates, and acetaminophen-induced hepatotoxic parameters (such as ALT and SDH activity) in serum were evaluated after intraperitoneal administration of acetaminophen, 500 mg/kg body weight, to rats. The plasma concentrations and the resultant AUC0-12 h of acetaminophen, acetaminophen-glucuronide, and acetaminophen-sulfate were significantly higher when blood samples were collected from the retro-orbital sinus than those from the jugular vein. The serum ALT activity at 3 and 24 h after administration of acetaminophen were significantly higher when the blood samples were collected from the retro-orbital sinus than those from the dorsal aorta.
