Efficacy and Safety of ARB-Based Combination Therapies for Treatment of Hypertension: A Systematic Review and Meta-analyses
摘要
Hypertension is leading non communicable disease associated with high morbidity and mortality. There is uncertainty about the superiority of angiotensin receptor blocker (ARB)–diuretic versus ARB–calcium channel blocker (CCB) combination for the treatment of hypertension.
AimThis meta-analysis compares the effectiveness of angiotensin receptor blocker (ARB)–diuretic versus ARB–calcium channel blocker (CCB) combination therapies in adults with hypertension.
MethodsRCTs were identified through PubMed, Embase, Scopus, and Cochrane Central; data were analyzed using RevMan 5.4.1 with a random-effects model. Primary outcomes were mortality, systolic blood pressure (SBP), and diastolic blood pressure (DBP); secondary outcomes included serum electrolytes and renal function.
Results3549 studies were identified based on database searches. 19 studies were included for analyses. Meta-analysis revealed no significant difference between both the combination therapies for primary outcomes: all-cause mortality [RR: 1.19 (95% CI: 0.85 to 1.65; p = 0.31)], SBP [MD: 1.24 mmHg (95% CI: − 0.48 to 2.96; p = 0.16; I² = 59%)], and DBP [MD: 0.62 mmHg (95% CI: − 0.15 to 1.38; p = 0.11; I² = 0%)]. The diuretic group showed significant changes in serum sodium, chloride, creatinine, e-GFR, and increased uric acid. Risk of bias was mostly low, with moderate to high evidence certainty.
ConclusionBoth ARB + CCB and ARB + diuretic combinations showed comparable effectiveness in lowering blood pressure and all-cause mortality in hypertensive adults. ARB + CCB seems to be having good safety profile, with better renal functions based on biomarkers.
