摘  要:目的进行重组人胰岛素40/60混合注射液的药代、药效动力学研究,并与重组人胰岛素30/70混合制剂、常规型胰岛素、中性鱼精蛋白胰岛素进行比较。方法本研究为阳性对照、单次剂量、开放标签、拉丁方交叉研究。2006年5月至2007年3月招募男性健康受试者20名分为4组,分别在4个试验日进行重组人胰岛素40/60混合、重组人胰岛素30/70混合、常规型胰岛素、中性鱼精蛋白胰岛素注射液4种制剂研究,每次试验间隔7~70d。在正常血糖葡萄糖钳夹平台上进行药代、药效动力学研究。结果4种胰岛素制剂的药代动力学和药效动力学参数经方差分析4组间差异均有统计学意义(均P〈0.05)。主要将其中两种不同比例混合的预混胰岛素制剂进行对比。受试制剂重组人胰岛素40/60混合注射液药代动力学达峰时间为(105.00±24.33)min,平均滞留时间为(321.77±56.29)min;而反映降糖作用的药效动力学峰效应时间为(167.75±26.48)rain,平均滞留时间为(248.33±14.96)rain。与参比制剂重组人胰岛素30/70混合注射液比较,药代动力学参数血胰岛素峰浓度[(91.67±13.03)mU/L比(84.96±14.75)mU/L,P:0.119]、达峰时间[(105.00±24.33)min比(122.25±39.35)min,P=0.128]、平均滞留时间[(321.77±56.29)min比(332.12±49.20)min,P=0.645]及0—16h血胰岛素浓度曲线下面积[(24918±6610)h·mU/L比(26768±8032)h·mU/L,P=0.084]差异均无统计学意义,但0—4h血胰岛素浓度曲线下面积[(16991±3673)h·mU/L比(12407±3441)h·mU/L,P=0.042]和0—8h血胰岛素浓度曲线下面积[(23283±4939)h-mU/L比(19397±5314)h·mU/L,P=0.046]差异有统计学意义。药效动力学各参数差异均无统计学意义(均P〉0.05)。受试制剂重组人胰岛素40/60混合注射液与30/70混合注射液相比Objective To study the pharmacokineties and pharmacodynamics of the 40/60 premixed recombinant human insulin injection preparation, and to compare with 30/70 preparation, regular insulin, and neutral protamine Hagedorn (NPH). Methods In this positive control, single dose, open label, Latin square crossover study, 20 male healthy volunteers were recruited from May 2006 to March 2007, and divided into four groups. On 4 test days, 40/60 preparation, 30/70 preparation, regular insulin, and NPH were administered to each of the 4 groups, the interval was 7 - 70 days before 2 test days. The pharmacokinetics and pharmacody- namics were evaluated by euglycemic glucose clamp technique. Results According to the analysis of vari- ance, there were statistically significant differences in pharmacokinetics and pharmacodynamics of the 4 insu- lin formulations between the 4 groups ( all P 〈 0. 05). For the 40/60 premixed recombinant human insulin, the pharmacokinetic parameter time to peak ( Tmax) and mean retention time (MRT) were ( 105.00 ± 24.33 ) minutes and (321.77 ± 56. 29) minutes, respectively; the glucose-lowering effects reflected by the pharma- codynamic parameter Tmax and MRT were (167. 75 ± 26. 48 )minutes and (248.33 ± 14. 96)minutes, respec- tively. Compared with 30/70 premixed recombinant human insulin, 40/60 preparation showed no significant differences in the pharmacokinetics parameters of blood insulin concentration, including peak concentration [ (91.67 ± 13.03 ) mU/L vs. ( 84. 96 ± 14. 75 ) mU/L, P = 0. 119 ], Tmax [ ( 105.00 ± 24. 33 ) minutes vs. ( 122. 25± 39. 35) minutes, P = 0. 128 ], MRT [ (321.77 ± 56. 29) minutes vs. (332. 12± 49. 20) minutes, P =0. 645] and area under the curve in 0 - 16 hours [ AUClas 0-16, (24 918±6 610)h mU/L vs. (26 768 ± 8 032)h mU/L, P= 0.0841; however, statistically significant differences were observed in AUCIns 0-4 [(16 991 ±3 673)h mU/L vs. (12 407 ±3 441)h mU/L, P=0.042] and AUCIns 0
