– Perindopril (S-9490) is a long-acting ACE inhibitor effective for 24 hours, primarily utilized in the management of high blood pressure, heart failure, or stable coronary artery disease. Available as perindopril arginine (with trade names such as Coversyl and Coversum) or perindopril erbumine (known as Aceon), both formulations are regarded therapeutically equivalent, according to the Australian Government’s Pharmaceutical Benefits Scheme—meaning they can be interchanged without clinical effect differences, though their dosing may vary due to distinct molecular weights. Notably, perindopril ranks among the most frequently prescribed ACE inhibitors, thanks to its extensive evidence base supporting its use in patients with hypertension, type 2 diabetes, coronary heart disease, and chronic heart failure. This review highlights perindopril’s organoprotective benefits that extend beyond its capacity to lower blood pressure.
