Abstrakt: Pigs were given large oral doses of paracetamol, amylobarbitone and amitriptyline. The effect of administering activated charcoal at varying intervals after dosing on the blood drug-level profiles of paracetamol and amylobarbitone was assessed by comparison with the profiles obtained when charcoal therapy was withheld. An appreciable effect on paracetamol absorption was demonstrated when charcoal was given up to l h after dosing. The amylobarbitone-dosed pigs exhibited delayed gastro-intestinal absorption of drug and this was substantially reduced by activated charcoal given 4 hrs after dosing. The pigs metabolised amitriptyline at too high a rate for meaningful studies to be undertaken with this drug.
