title: Effects of bacterial lipopolysaccharide on the pharmacokinetics of DA-8159, a new erectogenic, in rats.
abstract: Pharmacokinetic parameters of DA-8159 and one of its metabolites, DA-8164, were compared after intravenous and oral administration of DA-8159 at a dose of 30 mg/kg to control rats and rats pretreated with Klebsiella pneumoniae lipopolysaccharide (KPLPS). After intravenous and oral administration of DA-8159, most of the pharmacokinetic parameters of DA-8159 and DA-8164 were not significantly different between two groups of rats. This suggested that the pharmacokinetic parameters of DA-8159 and DA-8164 were not affected considerably by KPLPS.
