摘 要:目的研究美罗培南在肾功能不全患者中的血药浓度监测结果及药动学。方法选择2015年7月至2016年8月上海交通大学医学院附属新华医院急诊重症监护病房(ICU)收治的肾功能不全患者15例。选择同期本院就诊肾功能正常的感染患者14例。所有患者均静脉匀速滴注美罗培南0.5~1.0g,给药后5min和6h抽取血样,将血液离心后取血浆200斗l,采用高效液相色谱法测定血浆中美罗培南浓度,根据成人群体药动学模型,计算药动学参数。比较肾功能不全患者、肾功能正常的感染患者与文献中健康受试者的主要药动学参数。结果肾功能正常的感染患者给药后5min的血药浓度为30.99(15.46,55.96)mg/L,给药后6h的血药浓度为1.67(0.59,3.64)mg/L。肾功能不全患者给药后5min的血药浓度为48.65(33.09,69.30)mg/L,给药后6h的血药浓度为12.70(1.05,16.41)mg/L。14例肾功能正常的感染患者主要的药动学参数为最大血药浓度(Cmax)/剂量:34(16,61)μg/(ml·g);消除半衰期(t1/2)=1.78(1.51,2.53)h;美罗培南清除率(CL)=12.4(10.2,17.0)L/h;表观分布容积(V)=10.8(8.9,10.8)L;速率常数10(K10)=1.3(1.0,1.9)/h;K12=1.7(1.7,2.1)/h。15例肾功能不全患者主要的药动学参数为Cmax/剂量=52(40,74)μg/(ml·g);t1/2=3.68(2.21,5.36)h;CL=5.7(4.4,7.3)L/h;V=9.3(9.3,10.8)L;K10=0.6(0.5,0.7)/h;K12=2.0(1.7,2.0)/h。肾功能不全患者t1/2和Cmax明显高于健康受试者和肾功能正常的感染患者[(4.03±2.16)h比(0.97±0.08)、(2.22±1.32)h;(50±26)mg/L比(36±18)、(35±22)mg/L],CL和V明显低于健康受试者和。肾功能正常的感染患者[(5.8±1.4)L/h比(11.7±1.9)、(14.4±5.9)I/Objective To investigate plasma concentration and pharmacokinetic features of meropenem in patients with renal insufficiency. Methods From July 2015 to August 2016, 15 patients with renal insufficiency and 14 infected patients with normal renal function were enrolled in Xin Hua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. All patients had intravenous administration of meropenem 0. 5-1.0 g and was taken blood for plasma-drug concentration detection by high performance liquid chromatography method 5 nfin and 6 h after administration. Pharmaeokinetic parameters were calculated according to population pharmacokinetie model and analyzed among renal insufficiency patients, normal renal function infected patients and health people from literature. Results The median concentration of meropenem in patients with normal renal function was 30. 99 ( 15.46, 55.96) mg/L at 5 rain after administration and 1.67 (0. 59, 3. 64) mg/L at 6 h after administration. Concentrations of meropenem in patients with renal insufficiency at 5 min, 6 h after administration were 48.65 (33.09, 69. 30)mg/L and 12.70( 1.05, 16. 41 )rag/L, respectively. In infected patients with normal renalfunction, maximum concentration( Cmax )/dosage = 34 ( 16, 61 ) μg/( ml· g) ; half-life ( t1/2 ) = 1.78 ( 1.51, 2. 53 ) h; clearance rate (CL) = 12.4 ( 10. 2, 17. 0)L/h; apparent volume of distribution(V) = 10. 8 (8.9, 10. 8 )L; speed rate K10 = 1.3 ( 1.0, 1.9)/h; K1/2 = 1.7 ( 1.7, 2. 1 )/h. In patients with renal insufficiency, Cmax/dosage = 52(40, 74)μg/(ml ·g) ; t1/2 =3.68(2. 21,5.36)h; CL =5.7(4.4, 7.3)L/h; V=9. 3(9. 3, 10. 8) L; K10 = 0. 6(0. 5, 0. 7)/h; K1/2 = 2. 0 ( 1.7, 2. 0)/h. Values of t~/2 and Cm= in renal insufficiency patients were significantly higher and CL, V were significantly lower than those in health people and normal renal function infected patients [ (4. 03 ± 2. 16) h vs ( 0.97 ±0. 08 ), ( 2. 22 ± 1.32 ) h; �
