Perindopril, or perindopril arginine, (trade names include Coversyl and Aceon) is a long-acting ACE inhibitor. Perindopril is used to treat high blood pressure, heart failure or stable coronary artery disease. It is also available in a generic form, perindopril erbumine. According to the Australian government's Pharmaceutical Benefits Scheme website, based on data provided to the Australian Department of Health and Aging by the manufacturer, perindopril arginine and perindopril erbumine are therapeutically equivalent and may be interchanged without differences in clinical effect. However the dose prescribed to achieve the same effect will differ due to different molecular weights for the two forms.
