Aldosterone Synthase Inhibitors: a Review of Lorundrostat and Baxdrostat in Treatment-Resistant Hypertension
摘要
Aldosterone synthase inhibitors are a class of medication that target aldosterone biosynthensis while addressing the current limitations of conventional renin-angiotensin-aldosterone inhibitors. This review aims to explore the emerging role of lorundrostat and baxdrostat, efficacy and safety in the management of treatment-resistant and poorly controlled hypertension.
ResultsA narrative review was conducted, including six (6) clinical trials published between 2016 and 2025. Lorundrostat and baxdrostat demonstrated dose-dependent reductions in blood pressure across evaluated trials. In lorundrostat studies, plasma renin activity increased in association with aldosterone suppression, and an overall favorable safety profile was reported. Baxdrostat demonstrated selective inhibition of aldosterone synthase in early-phase studies, and studies reported mild hyperkalemia and decreased renal function at higher doses. Lorundrostat was found to have comparable efficacy in patients with and without suppressed plasma renin activity, based on subgroup analyses within individual trials.
ConclusionDirect head-to-head comparative data between lorundrostat and baxdrostat are not currently available, and differences in selectivity or off-target effects are derived from separate clinical investigations. While current data support their efficacy and safety in early clinical trials, further large-scale studies are needed to establish their long-term outcomes, cost-effectiveness, and integration into clinical practice guidelines.
