NONMEM is written in FORTRAN a programming language with exact sciences in mind. User defined models are possible when the standard models do not suffice. The latter has standard PKPD models ready to use. It is often used in combination with the subroutine package PREDPP. It is a powerful tool which can be used in the analyses of population pharmaokinetic (PK) and pharmacodynamic (PD) data. Is model analysis software used for fitting and simulation data.
