Title: Combination therapy of angiotensin converting enzyme inhibitor and aldosterone antagonist for reducing morbidity and mortality from cardiovascular disease
Abstract:Combinations of an ACE inhibitor, an aldosterone antagonist, and a loop diuretic are described for use in treatment of circulatory disorders. Of particular interest are therapies using captopril, enalapril or lisinopril co-administered with spironolactone. This co-therapy would be particularly useful to reduce the death rate or the number of non-fatal hospitalizations or prevent the progression of congestive heart failure in patients with cardiovascular disease.
