Buprenorphine propionate was also proven to be a prodrug of buprenorphine. It was comprised of only a one-step extraction procedure with ethyl acetate and normal-phase chromatography on a Betasil Silica column. The recoveries of buprenorphine and buprenorphine propionate were above 84%. Calibration graphs were linear for buprenorphine over the concentration range 2-1500 ng/ml and for buprenorphine propionate over the concentration range 20-1500 ng/ml with a coefficient of variation, both within- and between-day, or less than 10% at any level. The limits of quantitation of buprenorphine and buprenorphine propionate in human or animal blood were 2.0 and 20 ng/ml, respectively, based on a single-to-noise ratio of 3. The method has been successfully applied to pharmacokinetic studies of buprenorphine and buprenorphine propionate in rabbits. The results demonstrated that buprenorphine propionate was rapidly and totally converted to its parent drug, buprenorphine, following intravenous administration. Buprenorphine propionate is a prodrug of buprenorphine. ------>tmu_sno=None ------>sno=15171 ------>authors2=Liu KS ------>authors3=Kuei CH ------>authors4=Tzeng JI ------>authors5=Ho ST ------>authors6=Wang JJ ------>authors6_c= ------>authors=Liu SY ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c= ------>publish_area=0 ------>updateTitle=Simultaneous determination of buprenorphine and its prodrug, buprenorphine propionate, by high-performance liquid chromatography with fluorescence detection: application to pharmacokinetic studies in rabbits. ------>language=2 ------>check_flag=None ------>submit_date=None ------>country=None ------>no=2 ------>patent_SDate=None ------>update_bywho=None ------>publish_year=2005 ------>submit_flag=None ------>publish_month=4 |
