Urinary excretion of buprenorphine, norbuprenorphine, buprenorphine-glucuronide, and norbuprenorphine-glucuronide in pregnant women receiving buprenorphine maintenance treatment.
BACKGROUND Buprenorphine (BUP) is under investigation as a medication therapy for opioid-dependent pregnant women. We investigated BUP and metabolite disposition in urine from women maintained on BUP during the second and third trimesters of pregnancy and postpartum. METHODS We measured BUP, norbuprenorphine (NBUP), buprenorphine glucuronide (BUP-Gluc), and NBUP-Gluc concentrations in 515 uri...
متن کاملBuprenorphine metabolites, buprenorphine-3-glucuronide and norbuprenorphine-3-glucuronide, are biologically active.
BACKGROUND The long-lasting high-affinity opioid buprenorphine has complex pharmacology, including ceiling effects with respect to analgesia and respiratory depression. Plasma concentrations of the major buprenorphine metabolites norbuprenorphine, buprenorphine-3-glucuronide, and norbuprenorphine-3-glucuronide approximate or exceed those of the parent drug. Buprenorphine glucuronide metabolites...
متن کاملBuprenorphine and norbuprenorphine in hair of pregnant women and their infants after controlled buprenorphine administration.
BACKGROUND Buprenorphine is under investigation as a pharmacotherapeutic agent for treating opioid dependence in pregnant women. We hypothesized that there would be a relationship between the cumulative maternal dose of buprenorphine during pregnancy and the concentration of buprenorphine and norbuprenorphine in maternal and infant hair. METHODS This study examined buprenorphine and norbupren...
متن کاملOpioid plasma concentrations in methadone-and buprenorphine-maintained patients.
This is the first trial to compare the relationship of opioid plasma concentrations in methadone-versus buprenorphine-maintained subjects. Sixty subjects (19 females and 41 males) seeking treatment who met Diagnostic and Statistical Manual version IV (DSM-IV) criteria for opioid dependence were recruited and treated at the Drug Addiction Outpatient Clinic at the University of Vienna. Of these, ...
متن کاملBuprenorphine and Norbuprenorphine Determination in Mice Plasma and Brain by Gas Chromatography–Mass Spectrometry
A gas chromatography tandem mass spectrometry method for quantification of buprenorphine (BUP) and norbuprenorphine (NBUP) in brain and plasma samples from mice was developed and validated. Analytes were extracted from the brain or plasma by solid phase extraction and quantified within 20 minutes. Calibration was achieved by linear regression with a 1/x weighting factor and d4-buprenorphine int...
