Summary

R,S-Oxazepam and R,S-temazepam can be separated in their enantiomers by means of a chiral AGP column. The corresponding R- and S-glucuronide conjugates can be separated on a normal reversed-phase C18 column. Man conjugates the S-enantiomer of oxazepam and temazepam both better than the R-enantiomer. The urinary recovery of the glucuronides following either R,S,-oxazepam or R,S-temazepam almost amounts to 100% of the dose administered.
