- Wings for NONMEM
- WFN is a set of DOS batch command files and awk scripts to help NONMEM® users be more productive. The first version of WFN (Wheels for NONMEM) was written in 1989 at UC San Francisco. The unix csh and awk scripts evolved and were eventually ported to DOS in order to support NONMEM as part of the RIDO (Right Dose First Time) project.
- Census 2
- is a comprehensive project manager for NONMEM, providing detailed summary, comparison and overview of the runs comprising a given project, including the display of output data and post-run processing. The new version is a complete rewrite of Census from the ground up. In addition to adding cross-platform support, Census 2 incorporates a number of interface changes, including flexible run tagging and filtering, report output in HTML and LaTeX, a portable database file format, full support for NONMEM 7.2 (including support for multiple estimation steps), and too many others to mention.

The recent versions are PFIM Interface 2.1, for single response models which includes a graphical user interface, and PFIM 3.0 for multiple response models. Several new features are proposed. A library of usual PK models is available and other models can be written using an analytical form or using a differential equations system. Regarding optimisation, it can be performed using either the Simplex algorithm or the Fedorov-Wynn algorithm.

Simcyp is widely used by over 25 leading pharmaceutical companies for model-based drug development; from discovery to late clinical phases. All simulations are stochastic; however either individual or POPPK analyses can be applied for fitting data. The user-friendly interface is designed to facilitate access of various levels of expertise in nonlinear mixed effects approaches.
- is a unique software tool for whole-body physiologically-based pharmacokinetic (PBPK) modeling and simulation. In particular it allows the straight forward construction of highly specific PK models that may be used to summarize the existing data and to extract the most information out of the experimental results generated thus far.
- is a Fortran program (Normal approximation Inference in Models with Random effects based on Ordinary Differential equations) devoted to the estimation in Ordinary Differential Equations (ODE) models with random effects. Although maximum likelihood based approaches are valuable options, both numerical and identifiability issues favor a Bayesian approach which can incorporate prior knowledge in a flexible way. NIMROD estimations relies on a normal approximation of the posterior that can be obtained by computing the maximum of the posterior distribution (MAP) by maximizing a penalized likelihood. NIMROD can be downloaded freely together with libraries for Pharmacokinetics and HIV models.
