The effects of replacing beta-blockers with an angiotensin converting enzyme inhibitor on the quality of life of hypertensive patients.

The aim was to evaluate the effects of a change of treatment from beta-blocker to captopril on the quality of life of hypertensive patients. One hundred forty-nine mild to moderate hypertensive patients who were being treated with beta-blockers were randomly assigned to receive captopril (12.5 to 50 mg twice daily), or to continue on beta-blocker treatment (atenolol: 25 to 100 mg once daily [n = 121], or propranolol, 10 to 80 mg twice daily [n = 12]). When required, 25 mg hydrochlorothiazide was added in each group. The patients were followed over periods ranging from 6 to 12 months. Blood pressure, treatment side effects, and quality of life were monitored. Blood pressure was equally well managed in both groups, though a lower level of treatment was required in the captopril group. The captopril treated patients exhibited favorable changes in several aspects of quality of life: sleep-related, gastrointestinal, and physical activity-related symptoms improved from baseline to end of follow-up. Drowsiness and the ability to concentrate significantly improved in the captopril group only (P <.01). Change in treatment from beta-blocker to captopril resulted in equally well controlled blood pressure on a lower drug dose. Moreover, the change to captopril had a positive impact on the quality of life.
