DBSolveOptimum is a stand-alone software tool for the construction and analysis of mathematical models of biological systems. It is a succession and extension of DBSolve 5 and DBSolve 7, which were popular tools for systems biology. In addition to the capabilities of these software packages, DBSolveOptimum is implemented with new tools for extended data analysis and multiple simulations, which are important for simulation of virtual clinical trials and application of modern modeling techniques, like quantitative systems pharmacology, to problems arising in drug research and development. By this time, DBSolveOptimum has been successfully tested and applied for the development and analysis of both systems pharmacology and conventional PK/PD models of drugs. It is free for academic and industrial use.
