Objective

To establish a population pharmacokinetic model of amoxicillin and clavulanate potassium tablets in healthy Chinese subjects under fasting condition.

Methods

Based on the previously confirmed bioequivalence results, this study retrospectively collected the plasma concentration data of 18 subjects who received the test preparation and 17 subjects who received the reference preparation. The population pharmacokinetic model of amoxicillin was constructed using Phoenix NLME software. The effects of covariates such as gender, age, albumin, serum creatinine, creatine kinase, fasting blood glucose, and total cholesterol on pharmacokinetics were evaluated by forward inclusion and backward elimination methods. Model validation included goodness-of-fit plots, bootstrap method, and visual predictive check (VPC).

Results

The population pharmacokinetic model of amoxicillin in healthy subjects conformed to a two-compartment model with first-order elimination kinetics and lag time, which could well describe the data. Serum creatinine and body mass index (BMI) were significant covariates. The parameters of the final model were as follows: central volume of distribution (V)=51.56 L, peripheral volume of distribution (V2)=7.65 L; clearance (CL)=39.99 L·h-1, intercompartmental clearance (CL2)=1.78 L·h-1, absorption rate constant (Ka)=1.45 h-1. Serum creatinine had an impact on CL2 and Ka, while BMI affected V.

Conclusion

The two-compartment model with first-order elimination kinetics and lag time can better describe the in vivo absorption characteristics of amoxicillin after oral administration of amoxicillin and clavulanate potassium tablets in healthy subjects.

目的

构建阿莫西林克拉维酸钾片(amoxicillin and clavulanate potassium tablets)在中国健康人群中空腹状态下的群体药代动力学模型。

方法

本研究基于前期已证实的生物等效性结论,通过回顾性收集18例服用受试制剂和17例服用参比制剂患者的血药浓度数据,借助Phoenix NLME软件构建阿莫西林的群体药代动力学模型,通过向前纳入法和向后剔除法,考察性别、年龄、白蛋白、血清肌酐、肌酸激酶、空腹血糖、总胆固醇等指标对药代动力学的影响。模型验证包括拟合优度图、自举法、可视化检验(VPC)。

结果

阿莫西林在健康人群中的群体药动学数据可以较好地被具有吸收滞后时间的一级消除动力学二房室模型描述,血清肌酐、BMI值是显著的协变量。最终模型中心室分布容积(V)值为51.56 L,周边室分布容积(V2)为7.65 L;CL值为39.99 L·h-1,CL2值为1.78 L·h-1,Ka值为1.45 h-1,高血清肌酐的患者CL2更低,而高血清肌酐的患者Ka更高,高BMI患者V则更高。

结论

具有滞后时间的一级消除动力学二房室模型,更好地描述了健康人体口服阿莫西林克拉维酸钾片的体内吸收特征。

目的

构建阿莫西林克拉维酸钾片(amoxicillin and clavulanate potassium tablets)在中国健康人群中空腹状态下的群体药代动力学模型。

方法

本研究基于前期已证实的生物等效性结论,通过回顾性收集18例服用受试制剂和17例服用参比制剂患者的血药浓度数据,借助Phoenix NLME软件构建阿莫西林的群体药代动力学模型,通过向前纳入法和向后剔除法,考察性别、年龄、白蛋白、血清肌酐、肌酸激酶、空腹血糖、总胆固醇等指标对药代动力学的影响。模型验证包括拟合优度图、自举法、可视化检验(VPC)。

结果

阿莫西林在健康人群中的群体药动学数据可以较好地被具有吸收滞后时间的一级消除动力学二房室模型描述,血清肌酐、BMI值是显著的协变量。最终模型中心室分布容积(V)值为51.56 L,周边室分布容积(V2)为7.65 L;CL值为39.99 L·h-1,CL2值为1.78 L·h-1,Ka值为1.45 h-1,高血清肌酐的患者CL2更低,而高血清肌酐的患者Ka更高,高BMI患者V则更高。

结论

具有滞后时间的一级消除动力学二房室模型,更好地描述了健康人体口服阿莫西林克拉维酸钾片的体内吸收特征。

Objective

To establish a population pharmacokinetic model of amoxicillin and clavulanate potassium tablets in healthy Chinese subjects under fasting condition.

Methods

Based on the previously confirmed bioequivalence results, this study retrospectively collected the plasma concentration data of 18 subjects who received the test preparation and 17 subjects who received the reference preparation. The population pharmacokinetic model of amoxicillin was constructed using Phoenix NLME software. The effects of covariates such as gender, age, albumin, serum creatinine, creatine kinase, fasting blood glucose, and total cholesterol on pharmacokinetics were evaluated by forward inclusion and backward elimination methods. Model validation included goodness-of-fit plots, bootstrap method, and visual predictive check (VPC).

Results

The population pharmacokinetic model of amoxicillin in healthy subjects conformed to a two-compartment model with first-order elimination kinetics and lag time, which could well describe the data. Serum creatinine and body mass index (BMI) were significant covariates. The parameters of the final model were as follows: central volume of distribution (V)=51.56 L, peripheral volume of distribution (V2)=7.65 L; clearance (CL)=39.99 L·h-1, intercompartmental clearance (CL2)=1.78 L·h-1, absorption rate constant (Ka)=1.45 h-1. Serum creatinine had an impact on CL2 and Ka, while BMI affected V.

Conclusion

The two-compartment model with first-order elimination kinetics and lag time can better describe the in vivo absorption characteristics of amoxicillin after oral administration of amoxicillin and clavulanate potassium tablets in healthy subjects.
