A liquid chromatographic/electrospray ionization tandem mass spectrometric method for the quantification of the synthetic opiate buprenorphine (BUP), norbuprenorphine (NBUP), buprenorphine-3-beta-D-glucuronide (BUP-3-G) and norbuprenorphine-3-beta-D-glucuronide (NBUP-3-G) in human plasma was developed and validated. Identification and quantification were based on the following transitions: m/z 468 to 396 and 414 for BUP, m/z 414 to 326 and 340 for NBUP, m/z 644 to 468 for BUP-3-G and m/z 590 to 414 for NBUP-3-G. Calibration by linear regression analysis utilized deuteratated internal standards and a weighting factor of 1/x. The method was accurate and precise across a linear dynamic range of 0.6-50.0 ng ml(-1). Pretreatment of plasma samples using solid-phase extraction was sufficient to limit matrix suppression to <30% for all four analytes. The method proved to be suitable for the quantification of BUP and the related metabolites in plasma samples collected from BUP-maintained study participants.
