Summary

In a barbiturate dependent patient, the blood barbiturate was less than 0·2 mg% two and a half hours after an oral dose of 200 mg amylobarbitone sodium. Amylobarbitone was withdrawn, and the patient was maintained on phenobarbitone, with a blood barbiturate level that remained at about 4·0 mg% over several weeks. Themost likelyexplanation of the findings is that the oxidation of amylobarbitone, but not phenobarbitone, is accelerated in patients dependent on the former drug.
