Abstract:
AIM:To develop a SAS macro tool for calculating pharmacokinetic(PK)parameters using non-compartmental analysis(NCA)that is applica-ble to various routes and frequencies of drug ad-ministration.METHODS:By incorporating the prin-ciples of NCA PK parameter calculations,the struc-ture of the SAS macro program is designed and pro-grammed.The usage of the macro program is dem-onstrated through simulated examples.RESULTS:Based on NCA,this study programmed a SAS macro using SAS macro language to calculate both single-dose and steady-state complete PK parameters.It supports three modes of drug administration:ex-travascular,intravenous infusion,and intravenous bolus injection,as well as four algorithms for calcu-lating area under the curve(AUC).By comparing with authoritative calculation software,the results were found to be highly consistent across various calculation scenarios,with more accurate calcula-tions for the time of first measurable concentration(Tlag).CONCLUSION:The%M_CREATE_PK_PARAM-ETERS macro is a SAS macro that supports compre-hensive PK parameter calculations in NCA,provid-ing an accurate,efficient,and flexible solution for PK parameter estimation with broad application prospects.
