What this medicine is used for
APO-Eplerenone tablets are used to:
treat heart failure in patients who have experienced a heart attack.
reduce the risk of death or need for hospitalisations due to heart failure in patients
with chronic heart failure.
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 it works
Eplerenone belongs to a group of medicines called 'selective aldosterone blockers'
that stop the action of aldosterone, a substance made by your body.
Aldosterone 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. Eplerenone works by blocking the action of aldosterone and slowing
the progression of heart failure by reducing heart damage.
