【摘要】 目的比较利培酮分散片和普通片在健康人体的药动学。方法采用自身交叉对照试验设计,20名健康受试者在不同周期分别口服利培酮分散片和普通片各2 mg,采用高效液相色谱-串联质谱法测定血浆中利培酮和9-羟基利培酮浓度。应用DAS2.1.1软件进行药动学参数计算及生物等效性评价。结果利培酮普通片和分散片的利培酮主要药动学参数如下:ρmax分别为(14.03±6.54)和(13.77±7.73)μg·L-1,tmax分别为(1.36±0.71)和(1.17±0.81)h,t1/2分别为(3.59±1.69)和(3.87±1.78)h,AUC0-t分别为(66.02±46.79)和(73.05±59.85)μg·h·L-1,AUC0-∞分别为(71.26±48.00)和(78.97±63.48)μg·h·L-1。利培酮普通片和分散片的9-羟基利培酮的ρmax分别为(8.53±3.63)和(8.50±2.92)μg·L-1,tmax分别为(4.54±4.19)和(5.75±3.36)h,t1/2分别为(17.97±4.00)和(17.34±4.44)h,AUC0-t分别为(196.89±61.78)和(198.01±61.56)μg·h·L-1,AUC0-∞分别为(220.55±65.36)和(218.58±65.85)μg·h·L-1。结论利培酮分散片和普通片的药动学无显著差异,且两制剂具有生物等效性。

【Abstract】 AIM To compare the pharmacokinetic properties of dispersible and conventional tablet of risperidone in Chinese healthy volunteers.METHODS The clinical investigation was designed as a randomized and crossover study.A single oral dose(2 mg) of risperidone in either formulation was given to 20 healthy volunteers.The concentrations of risperidone and 9- hydroxy- risperidone(9- OH- RIP) in plasma were determined by HPLC- MS method.RESULTS The main pharmacokinetic parameters of risperidone of conventional and dispersible tablets were as follows:ρmax were(14.03 ± 6.54) and(13.77 ± 7.73) μg·L-1,tmax were(1.36 ±0.71) and(1.17 ±0.81) h,t1/2 were(3.59 ± 1.69) and(3.87+1.78) h,AUC0-t were(66.02 ± 46.79) and(73.05 ± 59.85) μg·h·L-1,AUC0-∞ were(71.26 ± 48.00) and(78.97 ± 63.48) μg·h·L-1, respectively.The main pharmacokinetic parameters of 9- OH- RIP of two risperidone tablets were as follows:ρmax were(8.53 ± 3.63) and(8.50 ± 2.92) μg·L-1 tmax were(4.54 ± 4.19) were(5.75 ± 3.36) h,t1/2 were(17.97 ± 4.00) and(17.34 ± 4.44) h,AUC0-t were(196.89 ± 61.78) and(198.01 ± 61.56) μg·h·L-1, AUC0-∞ were(220.55 ± 65.36) and(218.58 ± 65.85) μg·h·L-1,respectively.CONCLUSION The dispersible and conventional tablets of risperidone are bioequivalent in human body.
