Effect of bopindolol on the circadian blood pressure profile in essential hypertension.

The effect of bopindolol on circadian blood pressure and heart rate profile was evaluated by means of an automatic recording technique (Pressurometer II). Blood pressure and heart rate was measured every 15 min for 24 h in 11 ambulant hypertensive patients. Recordings were made after 2 weeks on placebo then after treatment for 4 and 8 weeks with single daily doses of 0.5 or 1 mg bopindolol, according to a double-blind crossover plan. The results show a significant fall in the mean 24-h values for systolic and diastolic blood pressure and heart rate on both dosages of bopindolol. The low-dose level had a more marked effect on the day phase of the blood pressure profile, whereas the high-dose level affected day and night phases equally. Over all, the circadian rhythms of blood pressure and heart rate were not influenced. In conclusion, bopindolol has a well-defined antihypertensive effect on the various phases of the 24-h blood pressure and heart rate profiles.
