N-GLUCOSIDES: NEW PHASE-II METABOLITES OF TWO BARBITURATES
The new phase-II N-glucoside metabolites of butobarbitone and pentobarbitone are identified and quantified in human urine after single doses of these drugs. The identification and quantification of these metabolites were carried out by mass spectroscopy technique (accurate mass measurement and high voltage scanning). It was found that the butobarbitone N-glucoside comprised 26% of the dos...
