Development of a microcomputer program for statistical evaluation of potential pharmacokinetic drug interactions

A simple and self-explanatory program in BASIC for the statistical evaluation of potential pharmacokinetic drug interactions is described. This program, using the data (times and drug concentrations) obtained from two different populations, and with the help of graphic computing techniques, allows the determination and statistical comparison of pharmacokinetic parameters (disposition constants, transfer rate constants, area under the concentration-time curves, etc.) for one- and two-compartment open models after intravenous or extravasal administration. The program is organized in subroutines so that it can be easily modified or extended to other pharmacokinetic models by the user.
