BACKGROUND : The efficacy and safety of sacubitril/valsartan used as an antihypertensive agent has not yet been completely assessed. Thus, to investigate them in elderly hypertensive patients, a meta-analysis has been performed.
METHODS : The meta-analysis incorporated only randomized controlled trials (RCTs) in which sacubitril/valsartan was compared with a reference drug. The mean reductions in systolic blood pressure (msSBP) and diastolic blood pressure (msDBP) in the sitting position as well as the mean reductions in ambulatory systolic blood pressure (maSBP) and ambulatory diastolic blood pressure (maDBP), were assumed as efficacy endpoints. Adverse events were taken as safety outcomes.
RESULTS : Five RCTs were included for a total of 1513 patients for analysis. In all studies, the comparator drug was an angiotensin receptor blocker (ARB) - valsartan in two cases and olmesartan in the remaining three cases. Compared with ARBs, there was a significant reduction in msSBP (weight mean difference [WMD] -5.41 mmHg, 95% CI: -7.0 to -3.8; P<0.01), msDBP (WMD=-1.22 mmHg, 95% CI: -2.15 to -0.3; P<0.01), maSBP (WMD=-4.58 mmHg, 95% CI: -5.62 to -3.54; P<0.01) and maDBP (WMD=-2.17 mmHg, 95% CI: - 2.78 to -1.56; P<0.01) in elderly hypertensive patients at 12 weeks.
CONCLUSIONS : Sacubitril/valsartan may reduce arterial pressure more efficaciously than ARBs in elderly hypertensive patients.
