1. What is Astudal and what is it used for

Astudal contains the active substance amlodipine, which belongs to a group of medicines known as calcium antagonists.

Astudal is used to treat high blood pressure (hypertension) or a certain type of chest pain called angina, including a rare type called Prinzmetal's or variant angina.

In patients with high blood pressure, this medicine works by relaxing blood vessels, so that blood passes through them more easily. In patients with angina, Astudal improves blood supply to the heart muscle, which receives more oxygen and as a result, chest pain is prevented. This medicine does not provide immediate relief of chest pain due to angina.

2. What you need to know before you take Astudal

• if you have very low blood pressure (hypotension).
• if you have a narrowing of the aortic valve (aortic stenosis) or cardiogenic shock (a disease in which the heart is unable to pump enough blood to the body).
• if you suffer from heart failure after a heart attack.
