What Inspra is used for
What Inspra does
This medicine is used to treat heart failure in patients who have experienced a heart attack.
A heart attack occurs when one of the major blood vessels supplying blood to your heart becomes blocked. This means that your
heart cannot receive the oxygen it needs and becomes damaged. This may lead to further problems, such as heart failure, irregular
heart rhythms and blood clots.
Heart failure means that the heart muscle is weak and cannot pump blood strongly enough to supply all the blood needed throughout
the body. Heart failure is not the same as heart attack, and may start off with mild or no symptoms. But as the condition
progresses, patients may feel short of breath or may get tired easily after light physical activity such as walking. Some
patients may wake up short of breath at night, or have to prop their heads up during sleep to avoid this problem. Fluid may
collect in different parts of the body, often first noticed as swollen ankles and feet.
How Inspra works
Your body makes a substance called aldosterone. It is important for regulating blood pressure and is one of the factors involved
in heart function. Sometimes aldosterone can cause changes in our body that lead to heart failure. Inspra works by blocking
the action of aldosterone, and slowing the progression of heart failure by reducing heart damage.
Inspra belongs to a group of medicines called 'selective aldosterone blockers' that stop the action of aldosterone.
