Abstract
A liquid chromatography-tandem mass spectrometry method for the simultaneous quantification of buprenorphine (BUP), norbuprenorphine (NBUP), buprenorphine glucuronide (BUP-Gluc), and norbuprenorphine glucuronide (NBUP-Gluc) in human urine was developed and fully validated. Extensive endogenous and exogenous interferences were evaluated and limits of quantification were identified empirically. Analytical ranges were 5-1,000 ng/mL for BUP and BUP-Gluc and 25-1,000 ng/mL for NBUP and NBUP-Gluc. Intra-assay and interassay imprecision were less than 17% and recovery was 93-116%. Analytes were stable at room temperature, at 4 degrees C, and for three freeze-thaw cycles. This accurate and precise assay has sufficient sensitivity and specificity for urine analysis of specimens collected from individuals treated with BUP for opioid dependence.Entities:
