OPT: a package of computer programs for parameter optimisation in clinical pharmacokinetics

A W Kelman, B Whiting, S M Bryson

    British Journal of Clinical Pharmacology
    |August 1, 1982
    PubMed
    Summary

    The OPT computer program aids patient-specific drug dose optimization using Bayesian statistics. It refines pharmacokinetic parameters for complex dosing and non-steady states, improving clinical drug management.
