Inspra is a mineral corticoid receptor, used for treating high blood pressure and improving survival rates in patients who have left ventricular systolic dysfunction and congestive heart failure following a heart attack. It works by blocking aldosterone which widens blood vessels and reduces fluid and sodium retention, lowering blood pressure to help prevent strokes, heart attacks, and kidney problems.
