Current Medical Research and Opinion
O De DivitiisV Ligouri


Fifteen out-patients with moderate hypertension were randomly and sequentially treated with atenolol, indapamide and a combination of the two drugs after a wash-out period of at least 1 week and a 2-week placebo run-in period. The duration of treatment was 4 weeks in each case. The dosage was 2.5 mg indapamide and 100 mg atenolol, in single tablets which were taken at 11.00 hours. All the treatment regimens produced a highly significant (p less than 0.001) reduction in systolic and diastolic, supine and standing blood pressure; these reductions were not significantly different for the single drugs but were significantly greater for the combined therapy. The number of patients reaching the end-point of a diastolic blood pressure of 95 mmHg or less was the same with either atenolol or indapamide, i.e. 7 (46.6%), but was greater with the combined therapy, i.e. 10 (66.6%). A significant (p less than 0.001) reduction in pulse rate was observed with the treatments involving atenolol. Acceptability of the treatments was very good; the number of volunteered and elicited complaints during the different treatments being less compared to the placebo period, particularly for the combined treatment. No significant difference was observed in...Continue Reading
