摘  要:目的建立ELISA方法研究聚乙二醇重组人生长激素(PEG—rhGH)注射液单次给药人体药代动力学。方法将30名健康受试者随机分成4组(其中两组为自身对照),分别单次皮下注射PEG—rhGH注射液(0.1mg·kg^-1、0.2mg·kg^-1、0.4mg·kg^-1)、注射用重组人生长激素(rhGH)(0.067mg·kg^-1)。ELISA法测定不同时间点PEG—rhGH、rhGH的血药浓度,并计算药代动力学参数。结果PEG—rhGH、rhGH血药浓度分别在0.3125~40.0000ng·ml^-1、0.3125~10.0000ng·ml^-1范围内线性关系良好,最低检测性均为0.3125ng·ml^-1,批间、批内RSD均〈15%。PEG-rhGH(0.1、0.2、0.4mg·kg。)、rhGH(0.067mg·kg^-1)的t1/2分别为:(31.70±4.70)h、(32.19±4.58)h、(30.39±5.93)h、(1.95±0.44)h,Tmax为:(22.20±9.82)h、(29.40±10.75)h、(40.80±8.39)h、(3.20±1.10)h,Cmax:(105.24±45.37)ng·ml^-1、(379.09±109.61)ng·ml^-1、(920.69±293.21)ng·ml^-1、(30.17±3.20)ng·ml^-1,CL/F:(26.97±13.86)ml·kg^-1·h、(9.21±4.05)ml.kg^-1·h、(6.29±2.87)ml·kg^-1·h、(284.26±43.47)ml·kg^-1·h,AUCO→∞:(4657.70±2337.30)ng·ml^-1·h、(25279.58±9407.63)ng·ml^-1·h、(74438.894-29007.81)ng·ml^-1·h、(240.974-39.40)ng·ml^-1·h.结论PEG--rhGH体内过程符合线性动力学特征,与rhGH相比,明显推迟达峰时间、延长半衰期、减慢清除率,具有长效特征。Objective To investigate the pharmacokinetics of PEGylated recombinant human growth hormone(PEG-rhGH) injection in healthy volunteers by ELISA. Methods 30 healthy male volunteers were subcutaneously injected PEG-rhGH 0.1 mg·kg^-1, 0,2 mg·kg^-1, and 0.4 mg·kg^-1 and rhGH 0.067 mg·kg^-1, respectively, 10 volunteers for each dose group. The serum concentrations of PEG-rhGH and rhGH were determined by ELISA method and the pharmacokinetic parameters calculated. Results The calibration curves were linear at the concentration range of PEG-rhGH from 0.312 5 to 40.000 0 ng·ml^-1 and that of rhGH from 0.312 5 to 10.000 0 ng·ml^-1, respectively, with both of intra- and inter-batch RSD 〈15%. The lowest detectable limit was 0.312 5ng·ml^-1 for both. The t1/2 of PEG-rhGH (0.1 mg·kg^-1, 0.2 mg.kg1, and 0.4 mg·kg^-1) and rhGH (0.067 mg·kg^-1) were ( 31.70±4.70 ) h, ( 32.19±4.58 )h, ( 30.39±5.93 ) h, and ( 1.95±0.44 )h, respectively; Tmax were ( 22.20±9.82 )h, ( 29.40±10.75 ) h, ( 40.80±8.39 ) h, and ( 3.20±1.10 ) h; Cmax, were ( 105.24±45.37 ) ng·ml^-1, ( 379.09±109.61 ) ng·ml^-1, ( 920.69±293.21 ) ng·ml^-1, and ( 30.17±3.20 ) ngoml-1; CL/F were ( 26.97±13.86 ) ml·kg^-1·h, ( 9.21±4.05 ) ml·kg^-1·h, ( 6.29±2.87 ) ml·kg^-1·h, and ( 284.26±43.47 ) ml·kg^-1·h ; and AUC0→∞ were (4 657.70±2 337.30 ) ng·ml^-1·h, ( 25 279.58±9 407.63 ) ng·ml^-1·h, ( 74 438.89±29 007.81 ) ng·ml^-1·h, and ( 240.97±39.40 ) ng·ml^-1·h. Conclusions PEG-rhGH is linear pharmacokinetics; compared with rhGH, it delays peak time, prolongs half-time, decrease clearance, and shows prolonged action.
