Efficacy and safety of lorundrostat in uncontrolled hypertension: a systematic review, meta-analysis, and meta-regression.

Background: Uncontrolled hypertension (UH), a severe form of hypertension, persists despite the use of three or more antihypertensive medications. Its growing prevalence, particularly in patients with comorbidities, necessitates novel therapeutic options. Lorundrostat, a selective aldosterone synthase inhibitor, presents a promising mechanism of action by directly reducing aldosterone synthesis while sparing cortisol production, potentially offering an effective and safer alternative to mineralocorticoid receptor antagonists. Objectives: Three randomized controlled trials (RCTs) comprising 1568 participants were included to evaluate the efficacy and safety of lorundrostat in adults with UH as a primary objective, with a decrease in diastolic blood pressure and the incidence of hyperkalemia, hypotension, and serious adverse events, including life-threatening conditions, hospitalization, significant disability, and events resulting in death, as secondary outcomes of the study. Methods: A systematic search of PubMed, Embase, ScienceDirect, Cochrane, and ClinicalTrials.gov up to July 2025 was conducted per PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Included RCTs compared lorundrostat to placebo in adult patients with resistant/UH. Outcomes were pooled using a random-effects model. Meta-regression explored moderators, including age, BMI, and comorbidities. Results: Three RCTs ( Conclusion: Lorundrostat demonstrates significant antihypertensive efficacy and a manageable safety profile in UH patients. Larger, long-term trials are warranted to further validate its safety across broader populations and complete its efficacy profile, emphasizing the unknown long-term cardiovascular outcomes of the intervention.
