Effects of poloxamer 407-induced hyperlipidemia on the pharmacokinetics of carbamazepine and its 10,11-epoxide metabolite in rats: Impact of decreased expression of both CYP3A1/2 and microsomal epoxide hydrolase.

The pharmacokinetics of carbamazepine (CBZ) and its active 10,11-epoxide metabolite (CBZ-E) were evaluated after intravenous and oral administration of 5 mg/kg CBZ to rats with hyperlipidemia induced by poloxamer 407 (HL rats) and controls. The total area under the plasma concentration-time curve (AUC) of CBZ in HL rats after intravenous administration was… (More)
