Aim: To compare the effects of captopril and atenolol on quality of life of hypertensive patients.
Methods: In a randomly allocated double-blind crossover trial with two 6-week treatment periods captopril at 25 mg twice a day or atenolol at 50 mg once a day were administered to 265 hypertensive patients (mean age 56 years; 55% men). Of these, 65% were newly treated hypertensives and 35% were previously uncontrolled on a diuretic alone. A seated diastolic blood pressure of 95-115 mmHg was required after a 3-week placebo run-in period. Any previous diuretic therapy was changed to hydrochlorothiazide (25 mg once a day) and the dose was kept constant throughout the trial. Newly diagnosed patients did not take a diuretic at any time. Quality of life was assessed from self-completed questionnaires measuring psychological well-being, symptomatic side effects of treatment, and activity and perceived well-being (a health index). A relative's perception of the patients' mood was also obtained where possible.
Results: Twelve patients withdrew on atenolol and 10 on captopril. No differences between the drugs were observed in quality of life measures, and 95% confidence intervals suggested that important differences were excluded.
Conclusion: We conclude that at the doses used in this trial there were no important differences between captopril and atenolol in their effects on quality of life.
