Dilevalol effectively lowered exercising heart rate and systolic blood pressure in a dose-dependent manner. Effects on blood pressure and heart rate were minimal at rest and during supine tilt.

Area of Science:

  • Pharmacology
  • Cardiovascular Physiology

Background:

  • Dilevalol is an investigational beta-blocker.
  • Understanding its cardiovascular effects is crucial for potential therapeutic applications.

Purpose of the Study:

  • To evaluate the dose-dependent effects of dilevalol on blood pressure and heart rate in normal volunteers.
  • To assess dilevalol's impact at rest, during exercise, and during a tilt maneuver.

Main Methods:

  • Eight healthy volunteers received placebo, 100 mg, 200 mg, or 400 mg of dilevalol.
  • Blood pressure and heart rate were measured at rest, during supine tilt, and during exercise.

Main Results:

  • Dilevalol demonstrated a dose-dependent reduction in exercising heart rate and systolic blood pressure up to 200 mg.

  • No significant effects on diastolic blood pressure were observed.
  • Tilt heart rate decreased significantly from 200 mg, with some non-dose-dependent fall in tilt systolic blood pressure.

    • Conclusions:

    • Dilevalol exhibits dose-dependent reductions in exercise-induced heart rate and systolic blood pressure.
    • Its effects are less pronounced at rest and during supine tilt.
    • Plasma concentration variability suggests hepatic metabolism influences dilevalol absorption.
