Effect of heptabarbital on bioavailability of bishydroxycoumarin in the rat

L Putcha et al. Res Commun Chem Pathol Pharmacol. 1978 Jan.

Abstract

The influence of oral administration of heptabarbital on the gastrointestinal absorption of bishydroxycoumarin (BHC) was investigated in rats. Pretreatment of the animals with 20 mg/kg heptabarbital twice dialy for three days prior to the administration of 50 mg/kg BHC resulted in a 40% decrease from controls in the area under the BHC plasma concentration time curve (AUC). Preliminary studies indicated that a similar decrease in gastrointestinal absorption of BHC could be seen following a single oral dose of heptabarbital administered concomitantly with the anticoagulant.
