摘要 目的对不同厂商生产的片剂进行生物等效性评价。方法按双周期交叉试验设计,22名健康志愿者单剂量po2 mg利培酮参比或试验制剂。用高效液相色谱质谱联用技术测定利培酮及其活性代谢产物9-羟基利培酮的血药浓度,计算药动学参数及相对生物利用度,判定两制剂是否等效。结果参比制剂和试验制剂的主要药动学参数分别为:利培酮AUC0-t(124.80±116.22)和(137.19±118.12)μg.h.L-1,ρmax(17.00±6.87)和(19.24±7.63)μg.L-1,tmax(1.52±0.93)和(1.32±0.58)h,Ke(0.19±0.13)和(0.18±0.12)h-1,t1/2Ke(7.58±8.72)和(6.31±4.65)h;9-羟基利培酮的AUC0-t(564.3±182.42)和(580.01±205.38)μg.h.L-1,ρmax(20.00±9.84)和(20.05±10.38)μg.L-1,tmax(5.93±3.59)和(5.70±3.18)h,Ke(0.032±0.007 8)和(0.034±0.008 0)h-1,t1/2Ke(23.15±6.07)和(21.50±4.62)h;总活性成分AUC0-t(692.54±235.57)和(720.80±260.22)μg.h.L-1,ρmax(32.00±9.42)和(33.89±13.02)μg.L-1,tmax(2.27±1.50)和(1.98±1.25)h,Ke(0.033±0.008 6)和(0.035±0.007 8)h-1,t1/2Ke(22.72±6.94)和(20.98±4.34)h。两种制剂的利培酮,9-羟基利培酮和总活性成分的主要药动学参数经方差分析、双单侧t检验和90%置信区间计算,表明两制剂生物等效。以利培酮,9-羟基利培酮和总活性成分计,相对生物利用度分别为(113.4±25.85)%,(104.6±20.83)%,(105.4±19.64)%。结论两种制剂生物等效。 OBJECTIVE To investigate the bioequivalenee of risperidone tablets in healthy volunteers. METHODS 2 mg reference or test tablets were given to 22 healthy male volunteers in a randomized twn-way crossover design. The concentrations of rispefidone and 9-hydrox-y-fispefidone were determined by HPLC/MS. The bioequivalence of two formulations were investigated by the analysis of variance, two one side t-test and 90% confidence interval test. RESULTS The pharmacokinetic parameters of fisperidone reference and test tablets were as follows: AUC0-t ( 124.80 ± 116.22) and ( 137.19 ± 118.12) μg·h·L^-1, ρmax( 17.00 ± 6.87) and ( 19.24 ± 7.63) μg·L·-1, tmax( 1.52 ± 0.93) and (1. 32 ± 0.58) h, Ke(0.19 ± 0.13) and (0.18 ± 0.12) h^-1, t1/2ke(7.58 ± 8.72) and (6.31 ± 4.65) h.The pharmacokinitic parameters of 9-hydroxy-risperidone were as follows:AUC0-t (564.3 ± 182.42) and (580.01 ± 205.38) μg· h· L^-1, ρmax (20.00 ± 9.84) and (20.05 ± 10.38) μg·L^-1,(5.93±3.59) and (5.70±3.18) h,Ke(0.032±0.007 8) and (0.034 ±0.0080) h^-1,t1/2ke(23.15±6.07) and (21.50 ± 4.62) h. The pharmacokinitic parameters of total active moiety were as iollows: AUC0-t (692.54 ± 235.57) and (720.80 ± 260.22) μg·h·L^-1,ρmax(32.00±9.42) and (33.89±13.02) μg·L^-1,tmax(2.27 ± 1.50) and (1.98± 1.25) h,Ke(0.033±0.008 6) and (0.035 ± 0.007 8) h^-1, t1/2Ke(22.72 ± 6.94) and (20.98 ± 4.34) h, respectively. The mean relative bioavailability of tested vs reference tablets were ( 113.4 ± 25.85) %, ( 104.6 ± 20.83) %, ( 105.4 ± 19.64) % for rispefidone, 9-hydroxy-risperidone and total active moiety respectively. CONCLUSION The two formulations are bioequivalent.
