Abstract
This study was carried out on 12 hospitalized hypertensive patients to assess the antihypertensive efficiency and the duration of action of a once daily dose of atenolol.
100 mg of atenolol was given at 8 am every day for 5 days. Before and during the therapeutic period, 24-h blood pressure recordings were obtained with a continuous, automatic, non-invasive method working on the principle of oscillometry (Dinamap 845.950). Atenolol induced a significant reduction in mean blood pressure from 119±3.6 to 102.3±4.7 (P<0.001). This effect was significant from the very first day of treatment and was maintained over the duration of the study in ten patients. The decrease in blood pressure induced by atenolol lasted 24 h. Clinical tolerance of atenolol was excellent. In particular no case of excessive bradycardia was noted.
