ADME WorkBench

The shortest path from chemical properties and preclinical data to human ADME prediction

You’re only minutes away from advanced in silicoPK prediction.

ADME WorkBench Capabilities

  • Flexible PK prediction platform including dozens of methods for absorption, distribution, metabolism and excretion prediction
  • Intuitive spreadsheet-based user interface
  • Open, extensible models: all model source code is delivered and installed with product modifiable with included acslX
  • Peer-reviewed, published prediction techniques


  • Multiple PK prediction techniques, including whole-body and lumped physiologically-based pharmacokinetic (PBPK) models, and allometry based on the Wajima method
  • Ability to integrate values of ADME parameters predicted from a broad range of methods
  • Simulation of a single compound or multiple compounds in batch mode
  • Simulation of tissue concentration at the macro level (whole organ) and micro level (cell, interstitial fluid) either for the bound or unbound drug

  • Prediction of human PK from in vitro or preclinical in vivo data
  • Oral uptake prediction based on an advanced multi-compartment GI model
  • Linear and saturable models for metabolism and active transport in gut and liver
  • Prediction of distribution from physicochemical and tissue composition data
  • Support for end-user customization of any of the provided PK/PBPK models.

acslX Integration (Included)

  • ADME WorkBench is built on the acslX computational engine, allowing all the computational analyses available in acslX to be used by the ADME WorkBench PBPK models
  • Maximum-likelihood based parameter estimation
  • Local and global sensitivity analysis
  • Bayesian analysis using MCMC sampling
  • Monte Carlo analysis
  • M scripting language support for user-defined analyses
