Comparison of atenolol 50 mg and 100 mg as initial treatment in uncomplicated mild to moderate hypertension

After screening a local population in the northern part of The Netherlands for hypertension, 59 patients with a diastolic pressure (DP) between 95 and 130 mmHg were randomized and treated either with 50 mg atenolol (n=29) or 100 mg atenolol (n=30) for 1 month. There was no significant difference between the two treatments, neither in the fall in systolic and diastolic pressures nor in the number of complaints reported. It is concluded that in the initial treatment of uncomplicated mild to moderate hypertension, 100 mg atenolol has no advantage over a 50 mg dose.
