What this medicine is used for
Quinapril is used to lower high blood pressure (also known as hypertension) and treat
High blood pressure:
Everyone has blood pressure. Blood pressure helps to move your blood all around your
body. Your blood pressure may be different at different times of the day and may be
affected by how busy or worried you are. You have high blood pressure when your blood
pressure stays higher than is needed, even when you are calm and relaxed.
There are usually no symptoms of high blood pressure. The only way of knowing that
you have high blood pressure is to have your blood pressure checked on a regular basis.
If high blood pressure is not treated it can lead to serious health problems, including
stroke, heart disease and kidney failure.
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 does not mean that the heart stops. Heart failure may start off
with 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. Fluid may collect in different parts of the
body, often first noticed as swollen ankles and feet.
How it works
Quinapril belongs to a group of medicines called angiotensin converting enzyme (ACE)
Quinapril works by widening your blood vessels, which reduces pressure in the vessels
and makes it easier for your heart to pump blood around your body. This increases
the supply of oxygen to your heart, so that when you place extra demands on your heart,
such as during exercise, your heart may cope better and you may not get short of breath

Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
This medicine is not addictive.
There is not enough information to recommend the use of quinapril in children.
