[Long-term therapy with nitrates. How can continuous effectiveness be achieved?].

W Rudolph, J Dirschinger, G Reiniger

    Fortschritte Der Medizin

    Summary

    Continuous nitrate therapy is not justified due to rapid tolerance development. Maintaining anti-ischemic effects requires a nitrate-free interval, with proven dosing regimens available for long-term treatment.

    Area of Science:

    • Pharmacology
    • Cardiovascular Medicine

    Background:

    • Nitrate medications are commonly used for anti-ischemic therapy.
    • Rapid tolerance development limits the efficacy of continuous nitrate administration.

    Purpose of the Study:

    • To evaluate the necessity of nitrate-free intervals for maintaining anti-ischemic effects during long-term treatment.
    • To identify effective dosing regimens that prevent tolerance.

    Main Methods:

    • Review of long-term controlled studies on nitrate therapy.
    • Analysis of dosing regimens for isosorbide dinitrate, isosorbide 5-mononitrate, and transdermal nitroglycerin.

    Main Results:

    • Continuous nitrate administration leads to rapid tolerance, diminishing anti-ischemic effects.

  • Implementing a nitrate-free interval effectively prevents tolerance development.
  • Documented effective dosing regimens exist for various nitrate formulations.

    • Conclusions:

    • Continuous nitrate therapy is not clinically justified due to tolerance.
    • A nitrate-free interval is essential for sustained anti-ischemic efficacy in long-term nitrate treatment.
    • Effective long-term treatment strategies incorporating nitrate-free intervals are available.
