RT Journal Article SR Electronic T1 Pentobarbital pharmacokinetics in the normal and in the hepatectomized rat. JF Journal of Pharmacology and Experimental Therapeutics JO J Pharmacol Exp Ther FD American Society for Pharmacology and Experimental Therapeutics SP 111 OP 116 VO 194 IS 1 A1 F W Ossenberg A1 M Peignoux A1 D Bourdiau A1 J P Benhamou YR 1975 UL http://jpet.aspetjournals.org/content/194/1/111.abstract AB The pharmacokinetics of pentobarbital, a barbiturate metabolized by the liver, was compared in normal and in hepatectomized rats. The blood concentration time curve following a single intravenous injection of pentobarbital was fitted to a two-compartment open model. Both the volume of the central compartment and the elimination rate constant were significantly reduced in hepatectomized rats. It is concluded that the liver plays a role both in the metabolism and the distribution of pentobarbital.
