Abstract:OBJECTIVE A method was established to study the pharmacokinetics of perospirone in human plasma. METHODS Healthy volunteers received perospirone tablets (low doses,medium doses,high doses,multi doses), and drug concentrations in plasma were determined by HPLC-MS. RESULTS Pharmacokinetie parameters of perospirone after single oral doses (4,8,16mg) were as follow:V/F: (3623.2 ± 1358.8), (4224.4 ± 2075. 9) and (3712.9 ± 1542.5) L;Tmax were (1.92 ± 0.56), (1.79±0.45) and (1.79 ± 0.62) ; CL/F were (390.4 ± 140.0), (422.99± 156.21) and (375.4± 131.6)L·h^-1,T1/2β were (6.60± 1.62), (6.78 ± 1.38) and (6.73 ±0.99) h;MRT(0-24) were (6.58± 1.27), (6.74 ±0.81) and (6.60±0.58)h;Cmax were (1.38 ± 0.38), (2. 79 ± 0.78) and (5.68 ± 1.80)ug·L^-1; AUC(0- 24) were (7.56 ± 2.40), ( 15.48 ± 4.23) and (30.88 ± 9.00)ug·h·L^-1; the essential pharmacokinetic parameters after oral multi-doses (8mg, t. i. d) were as follow: T1/2β: (6.83 ± 1.71)h, Tmax(1.90 ± 0.46)h, MRT(0- 24) : (6.46 ± 0.58)h, Cssmax: (4.44 ± 0.84) ug·L^-1, Cssmin: ( 1.08 ± 0. 48 )ug·L^-1, Cav: (2.18 ± 0.57 ) ug·L^-1, DF : ( 1.60 ± 0.35 ), AUCss(0 - 8) : ( 17.42 ± 4.59 ) ug·h·L^-1 CONCLUSION The method is sensitive, the results were accurate, a two-compartment open pharmacokinetie model is adapted to of concentration-time data analysis perospirone in plasma, the main pharmacokinetic parameters are similar to those reported abroad.
