    Abstract:
    1. Forty patients with moderate to severe hypertension and daytime ambulatory diastolic blood pressure > or = 90 mm Hg were randomized double-blind to once-daily treatment with either quinapril up to 20 mg (n = 20) or atenolol up to 100 mg (n = 20) as single drugs or in combination with hydrochlorothiazide 25 mg over a period of 12 weeks. 2. Conventional and ambulatory blood pressure, heart rate, side effects and metabolic changes were compared at the end of the run-in period on placebo, after 4 weeks on monotherapy and at the end of the 12-week period of active treatment. 3. Quinapril and atenolol reduced conventional blood pressure equally with substantial additional effect seen on combination therapy. The two regimens induced a significant decrease in ambulatory BP. However, the atenolol treated ambulatory hypertensive group experienced significantly greater decreases in diastolic blood pressure during 24 h, awake and sleep periods than did the quinapril group. 4. Adverse reactions were mild with both drugs except for severe Raynaud phenomenon in one patient in the atenolol group. Triglyceride levels were significantly increased with atenolol alone and in combination with hydrochlorothiazide. 5. Thus, within the limits of the dose ranges tested, quinapril and atenolol as single drugs or in combination with hydrochlorothiazide reduce significantly conventional and ambulatory blood pressure in moderate to severe hypertensives, but atenolol is more effective in reducing ambulatory diastolic blood pressure.
