Efficacy and safety of selective aldosterone synthase inhibitors for blood pressure reduction in patients with CKD: a meta-analysis of randomized controlled trials

In brief

Selective aldosterone synthase inhibitors cut systolic BP by roughly 8 mmHg in CKD patients

A meta-analysis of five randomized trials (1,148 participants) found that these drugs reduced systolic blood pressure by about 8 mmHg and lowered albuminuria by roughly one-third compared with placebo, while modestly decreasing diastolic pressure. Kidney function showed a small decline and hyperkalemia was more common, leaving safety and long-term renal impact uncertain.

Abstract

Aldosterone synthase inhibitors (ASIs) demonstrated significant blood pressure (BP) lowering efficacy in patients with uncontrolled hypertension, but evidence in chronic kidney disease (CKD) remains limited. This meta-analysis explores the effects of selective ASIs on BP levels in CKD. Secondary outcomes were albuminuria (UACR), eGFR change and hyperkalemia incidence. Five RCTs (1,148 patients) were included; 2 used baxdrostat, 2 lorundrostat, and 1 study used vicadrostat. Treatment with ASIs was associated with a significant placebo-adjusted reduction in SBP of-7.9 mmHg [95% confidence interval (CI) -10.0 to -5.9, I2 = 0%] and DBP of -3.1 mmHg (95% CI -5.9 to -0.2, I2 = 62%) and reduced UACR by -31.7% (95% CI -54.5 to -8.9, I2 = 91%). The pooled placebo-adjusted eGFR change was -2.05 ml/min/1.73 m2 (95% CI -3.15 to -0.95, I2 = 0%). The risk of hyperkalemia was higher with ASIs, but with high heterogeneity (risk ratio, 4.04 [95% CI 0.94 to 17.35], I2 = 76%). In conclusion, selective ASIs present a potential treatment option for BP control and albuminuria reduction in patients with CKD.
