    Summary
    This summary is machine-generated.

    Evaluating novel antiarrhythmic and antianginal drugs presents challenges. However, data from acute and course treatments largely agree on drug efficacy, though long-term outcomes are crucial for final assessment.

    Area of Science:

    • Pharmacology
    • Clinical Trials
    • Cardiovascular Medicine

    Background:

    • Assessing the clinical efficacy of new antiarrhythmic and antianginal drugs faces methodological hurdles.
    • Existing studies often lack comprehensive long-term outcome data.

    Purpose of the Study:

    • To discuss methodological difficulties in evaluating novel cardiovascular drugs.
    • To present combined data on drug efficacy from acute and course treatments.
    • To emphasize the importance of long-term outcomes in determining drug value.

    Main Methods:

    • Review and synthesis of combined data on drug efficacy.
    • Comparison of results from acute drug testing versus course treatment.
    • Analysis of drug interactions, exemplified by propranolol and nifedipine.

    Main Results:

    • A high degree of agreement exists between acute testing and course treatment data for most antianginal and antiarrhythmic drugs.
    • Drug interactions, like that between propranolol and nifedipine, can potentiate effects despite opposing pharmacodynamic actions.

    Conclusions:

    • Acute and course treatment data generally align, providing reliable short-term efficacy assessments.
    • The ultimate value of a drug is best determined by its impact on long-term clinical outcomes.
