Non-compartmental analysis (NCA) is used at all stages of drug development and is a key method to understand the pharmacokinetic properties of a compound. Bioequivalence analysis of the NCA parameters is a critical step to investigate generic formulations, food effects or drug-drug interactions.
PKanalix belongs to the MonolixSuite applications, and performs NCA and CA (compartmental analysis) and includes a bioequivalence module starting from the 2021 version.
As NCA and bioequivalence are commonly part of filings to the regulatory agencies, tools implementing these methods must be appropriately validated. For historical reasons, Phoenix WinNonLin is considered as the standard. In this work, we rigorously compare the results of PKanalix with those of WinNonLin.
