Introducing PoPy

Overview

PoPy is a Python based PK/PD (pharmacokinetic/pharmacodynamic) modelling system.

PoPy’s features include:-

PoPy consists of a powerful set of Command Line Tools and script files, to enable you to analyse a PK/PD data file quickly and efficiently, whilst minisimising errors due to an elegant and intuitive syntax.

PoPy makes it easy to fit models to data, but also has the ability to generate new data to test hypothetical scenarios.
