    Area of Science:

    • Pharmacology
    • Clinical Research
    • Health Services Research

    Background:

    • Drug development follows a sequential process: laboratory (Phase O), preclinical, Phase II (hypothesis generation), Phase III (hypothesis testing), and Phase IV (routine treatment).
    • Each phase has unique objectives and methodologies for evaluating therapeutic interventions.

    Purpose of the Study:

    • To delineate the specific objectives and methodologies of Phase IV therapeutic evaluation.
    • To highlight the importance of non-reactive research designs for studies involving healthcare practitioners.

    Main Methods:

    • Review of the established phases of therapeutic development.
    • Emphasis on the distinct characteristics of Phase IV research, focusing on real-world application.
    • Discussion of specialized research designs for practitioner-involved studies.
