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
dose with tl/2= 44h, while the pentobarbitone N-glucoside was 43% with
t1/2= 40h.
