ABSTRACT
Objective To evaluate efficacy and safety of fixed combination of nitrendipine and atenolol in treatment for patients with mild to moderate essential hypertension and their optimal dosage matching.Methods Totally,275 patients with essential hypertension were selcted from seven hospitals in Shanghai,Nanjing and Suzhou,China and randomized into five groups with same proportional probability in a double-blind,double-dummy,parallel active-controlled,multi-center clinical trial,receiving fixed combination of nitrendipine and atenolol at three different dosage matching (nitrendipine/atenolol 5/12.5 mg,5/10 mg,5/7.5 mg for groups 1,2 and 3),and nitrendipine (10 mg for group 4) or atenolol (25 mg for group 5),respectively for eight weeks.Results Mean reduction of diastolic blood pressure (DBP)was (17±7) mm Hg,(18±9) mm Hg and (17±7) mm Hg for groupl,2 and 3,respectively from the baseline,significantly greater than that in groups 4 and 5[(13±7) mm Hg and (12±6) mm Hg,respectively].Mean reduction of systolic blood pressure (SBP) was (21 ±11)mm Hg,(24±12) mm Hg,(23±11) mm Hg,(19±13) mm Hg and (18±9) mm Hg,respectively for the five groups from the baseline,and the reduction in group 2 was significantly greater than that in group 5,with an overall efficacy of 94.4%,98.1% and 88.2% for groups 1,2 and 3,respectively,all statistically higher than that in group 5 (71.4%) with P<0.01,eight weeks after treatment.The ratio of patients with increased dose of antihypertensive agents in week 5 was lower in group 2 than that in the other four groups,with mild adverse reaction only,no obvious change in laboratory biochemical examinations,and no needs in special management.Conclusions Fixed combination of atenolol and nitrendipine with an optimal doses of 5 mg and 10 mg respepctively was effective and safe for mild and moderate hypertension with good tolerance.
