TOPFIT - A PC-BASED PHARMACOKINETIC-PHARMACODYNAMIC DATA-ANALYSIS PROGRAM

The program TopFit was developed and validated within the European pharmaceutical industry. It provides both pharmacokinetic data analysis support for international regulatory submissions of new drugs, and sophisticated techniques for model-based kinetic/dynamic evaluation during drug development. TopFit features are: (1) non-compartmental methods; (2) standard compartment models assembled from input and disposition modules; (3) a potentially unlimited number of linear user-defined models that accomodate metabolites, effects, and absorption profiles; (4) a library of 24 non-linear models. No user programming is required. A well-defined file structure allows ready exchange of data with other programs such as SAS. TopFit version 2.0 is now commercially available, with comprehensive documentation, in the form of an MS-DOS application for the PC.
