【摘要】 目的评价2种瑞舒伐他汀钙片在中国健康受试者的生物等效性(BE)。方法用单剂量、开放、随机、双周期交叉设计。32名健康受试者随机分为2组,单次空腹口服瑞舒伐他汀钙片受试制剂与参比制剂10 mg,另32名健康受试者随机分为2组,单次餐后口服瑞舒伐他汀钙片受试制剂与参比制剂10 mg,用LC-MS/MS法测定血浆中瑞舒伐他汀的浓度,用WinNonlin 6. 4软件按非房室模型计算药代动力学参数,并进行生物等效性评价。结果单次空腹口服瑞舒伐他汀钙片受试制剂(32名)与参比制剂10 mg(31名)后的主要药代动力学参数如下:Cmax分别为(16. 80±7. 53)和(15. 50±5. 76)μg·L-1; tmax分别为(3. 75±1. 24)和(3. 71±1. 42) h; t1/2分别为(12. 60±3. 25)和(12. 10±3. 23) h;AUC0-t分别为(170. 00±67. 30)和(164. 00±61. 80)μg·L-1·h; AUC0-∞分别为(172. 00±68. 00)和(166. 00±62. 60)μg·L-1·h。32名受试者单次餐后口服瑞舒伐他汀钙片受试制剂与参比制剂10 mg后的主要药代动力学参数如下:Cmax分别为(7. 16±5. 39)和(7. 04±4. 15)μg·L-1; tmax分别为(3. 41±1. 56)和(3. 75±1. 81) h; t1/2分别为(13. 00±3. 98)和(12. 30±3. 49) h; AUC0-t分别为(88. 70±51. 20)和(86. 20±45. 30)μg·L-1·h; AUC0-∞分别为(90. 80±51. 80)和(87. 90±45. 60)μg·L-1·h。31名入选BE集空腹给药受试制剂对于参比制剂的Cmax比值为(1. 06±0. 22),平均相对生物利用度:AUC0-t为(102. 65±17. 83)%,AUC0-∞为(102. 74±17. 39)%,2种制剂的AUC0-t、AUC0-∞和Cmax经对数转换后90%置信区间分别为96. 30%~106. 93%,96. 61%~106. 91%和97. 07%~110. 83%。32名餐后给药受试制剂对于参比制剂的Cmax比值为(1. 00±0. 22),平均相对生物利用度:AUC0-t为(103. 16±21. 08)%,AUC0-∞为(103. 41±20. 92)%,2种制剂的AUC0-t、AUC0-∞和Cmax经对数转换后90%置信区间分别为95. 04%~107. 52%,95. 41%~107. 72%和91. 46%~103. 58%。结论无论空腹还是餐后单次口服2种瑞舒伐他汀钙片在中国健康受试者体内均具有生物等效性。
【Abstract】 Objective To evaluate the bioequivalence( BE) of the two rosuvastatin calcium tablets in Chinese healthy subjects. Methods A single oral dose 10 mg of test and reference rosuvastatin calcium tablets were administered fasted to 32 subjects and other 32 subjects were administered with food according to an open randomized crossover design. The concentrations of rosuvastatin in plasma were determined by LC-MS/MS method. The pharmacokinetic parameters were calculated and the bioequivalence was compared by non-compartment model of Win Nonlin6. 4 program. Results The main pharmacokinetics parameters of test( 32 subjects) and reference( 31 subjects) rosuvastatin calcium tablets administered fasted were as follows: Cmaxwere( 16. 80 ± 7. 53) and( 15. 50 ± 5. 76) μg·L-1;tmaxwere( 3. 75 ± 1. 24) and( 3. 71 ± 1. 42) h; t1/2 were( 12. 60 ± 3. 25) and( 12. 10 ± 3. 23) h; AUC0-twere( 170. 00 ± 67. 30) and( 164. 00 ± 61. 80) μg·L-1·h; AUC0-∞were( 172. 00 ± 68. 00) and( 166. 00 ± 62. 60)μg·L-1·h. The main pharmacokinetics parameters of test and reference( 32 subjects) rosuvastatin calcium tablets administered with food were as follows: Cmaxwere( 7. 16 ± 5. 39) and( 7. 04 ± 4. 15) μg·L-1; tmaxwere( 3. 41 ± 1. 56) and( 3. 75 ± 1. 81) h; t1/2 were( 13. 00 ± 3. 98) and( 12. 30 ± 3. 49) h; AUC0-twere( 88. 70 ± 51. 20) and( 86. 20 ± 45. 30) μg·L-1·h; AUC0-∞were( 90. 80 ± 51. 80) and( 87. 90 ± 45. 60)μg·L-1·h. The Cmaxratio of test to reference drug administered fasted state was( 1. 06 ± 0. 22),the relative bioavailability were( 102. 65 ± 17. 83) % calculated by F( AUC0-t) and( 102. 74 ± 17. 39) % calculated by F( AUC0-∞); The 90% CIs for AUC0-t,AUC0-∞and Cmaxwere 96. 30%-106. 93%,96. 61%-106. 91% and97. 07%-110. 83%. The Cmaxratio of test to reference drug administered with food was( 1. 00 ± 0. 22),the relative bioavailability were( 103. 16 ± 21. 08) % calculated by F( AUC0-t) and( 103. 41 ± 20. 92) % calculated by F( AUC0-∞); The 90% CIs for AUC0-t,AUC0-∞and Cmaxwere 95. 04%-107. 52%,95. 41%-107. 72% and91. 46%-103. 58%. Conclusion The exposures were equivalent between two rosuvastatin calcium tablets administered with food or fasted in Chinese healthy subjects.
