Efficacy and Safety Comparative of Sacubitril/Valsartan vs. Olmesartan in the Treatment of hypertension: A Meta-analysis of RCTs.

BACKGROUND

Sacubitril/valsartan (LCZ696) is a widely used drug for hypertension in Asia, popular for its efficacy and safety. However, there has been no comprehensive literature review comparing it with olmesartan. This meta-analysis compared the antihypertensive and adverse effects of sacubitril/valsartan and olmesartan.

METHODS

We conducted a comprehensive search of Pubmed, Web of Science, Embase, Cochrane Library, and ClinicalTrials.gov databases to identify eligible randomized controlled trials (RCTs). The data were then analyzed and processed using Revman 5.4 and Stata SE14 software.

RESULTS

Six RCTs with 4,127 patients were identified, showing that LCZ696 had better blood pressure control than olmesartan; mean sitting systolic and diastolic blood pressure, sitting pulse pressure, 24-hour ambulatory systolic blood pressure, and 24-hour ambulatory diastolic blood pressure were significantly decreased with LCZ696 compared with olmesartan. No significant difference between LCZ696 and olmesartan was observed in the occurrence of the majority of adverse events, with a decreased probability of headache in patients with sacubitril/valsartan compared with olmesartan. The subgroup analysis showed treatment with 400 mg/d LCZ696 was better than olmesartan in reducing serious adverse events.

CONCLUSIONS

Sacubitril/valsartan was better than olmesartan in controlling blood pressure in patients with hypertension, with relatively higher safety.
