Aim : To compare the efficacy and safety of eprosartan and enalapril to lower systolic blood pressure in elderly patients with essential hypertension. Methods : 334 patients >65 years with sitting systolic blood pressure (sitSBP) &#83 160 mmHg and diastolic blood pressure (sitDBP) 90–114 mmHg were randomized to 12 weeks of double-blind treatment with eprosartan, 600–800 mg once daily (o.d.) or enalapril (5–20 mg o.d.), with flexible dose titration to lower systolic blood pressure below 140 mmHg. The primary outcome measure was change in sitSBP at endpoint. Results : Least-squares mean changes from baseline in sitSBP were–18.0 and–17.4 mmHg in the eprosartan and enalapril groups, respectively (difference eprosartan– enalapril–0.6, 95% confidence interval, CI,–4.1 to 3.0, p = 0.76). The corresponding figures for sitDBP were–9.4 and–9.6 mmHg (difference eprosartan–enalapril 0.2, 95% CI–1.7 to 2.0, p = 0.84). Normalization and response rates were also similar in the two groups. Adverse events were recorded in 61 (35.7%) patients on eprosartan (one with dry cough) and 83 (50.9%) patients on enalapril (10 with dry cough). Conclusions : Eprosartan and enalapril were equally effective in reducing sitSBP and sitDBP in elderly patients with predominantly systolic hypertension. Eprosartan was better tolerated and, in particular, lacked the propensity of enalapril to cause dry cough.
