Effect of nebivolol monotherapy or combination therapy on blood pressure levels in patients with hypertension: an updated systematic review and multilevel meta-analysis of 91 randomized controlled trials.

aimsTo systematically appraise and summarize the available evidence from published randomized controlled trials considering the effect of nebivolol on blood pressure in patients with hypertension.

methodsLiterature search was performed through Medline (via PubMed), Cochrane Library and Scopus until December 15, 2023. Double-independent study selection, data extraction and quality assessment were performed. Evidence was pooled with three-level mixed-effects meta-analysis.

resultsIn total, 7,737 participants with hypertension, who were treated with nebivolol, were analyzed across 91 RCTs. Nebivolol was associated with significantly greater reduction in office systolic and diastolic BP compared to placebo (MD = - 6.01 mmHg; 95% CI = [- 7.46, - 4.55] and MD = - 5.01 mmHg; 95% CI = [- 5.91, - 4.11], respectively). Moreover, resulted a similar reduction in systolic BP (MD = - 0.22 mmHg; 95% CI = [- 0.91, 0.46]) and a significantly greater reduction in diastolic BP compared to the active comparator (MD = - 0.71 mmHg; 95% CI = [- 1.27, - 0.16]). When considering the effect of nebivolol on 24-hour ambulatory BP, notable reductions were observed compared to placebo. In contrast, compared to the active comparators, there was no significant difference in systolic BP reduction, but a significant reduction in diastolic BP favoring nebivolol. Based on moderator analyses, the impact of nebivolol on the pooled estimates remained independent of the dose of nebivolol, age, male sex, trial duration, body mass index (BMI), baseline diabetes, heart failure, and baseline systolic and diastolic BP.

conclusionNebivolol, compared to placebo, showed a significant BP reduction and was non-inferior to other active comparators in terms of BP reduction.
