1 What Amlodipine tablets are and what they are used for

Amlodipine tablets contain the active substance amlodipine mesilate monohydrate. Amlodipine belongs to a group of medicines called calcium antagonists. It is used to treat:

  • high blood pressure (hypertension).
  • angina pectoris (pain in the chest caused by blockages in the arteries leading to the heart) or chest pain classed as vasospastic angina pectoris (or Prinzmetal’s angina).

In patients with high blood pressure, your medicine works by relaxing blood vessels, so that blood passes through them more easily. In patients with angina, Amlodipine tablets works by improving blood supply to the heart muscle, which then receives more oxygen, and as a result chest pain is prevented. Your medicine does not provide immediate relief of chest pain from angina.

2 What you need to know before you take Amlodipine Tablets

  • are allergic to amlodipine, dihydropyridine derivatives or any of the other ingredients of this medicine (listed section 6) or to any other calcium antagonists. This may be itching, reddening of the skin or difficulty in breathing.
  • are in shock including shock caused by heart problems (a condition where your heart is unable to supply enough blood to the body)
  • suffer from an obstruction in the heart caused by an extreme narrowing of the heart valves (aortic stenosis)
