How does it work?
This medication contains two active ingredients, aspirin and dipyridamole.
Aspirin belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). It works by blocking the action of a substance in the body called cyclo-oxygenase. Cyclo-oxygenase is involved in the production of various chemicals in the body. These are known as prostaglandins, prostacyclins and thromboxane.
In high doses, blocking cyclo-oxygenase prevents the production of prostaglandins. Prostaglandins are produced in response to injury or certain diseases and would otherwise go on to cause pain, swelling and inflammation. High doses of aspirin are therefore used to relieve pain and inflammation.
Aspirin in low doses (e.g. 75mg) does not have this effect and is used instead as an anti-clotting or blood-thinning agent. In low doses, blocking cyclo-oxygenase prevents the production of thromboxane by blood cells called platelets. Thromboxane is one of the chemicals that causes platelets to clump together and start off the clotting process. Stopping its production therefore reduces the likelihood of clots forming in the blood.
Dipyridamole belongs to a group of medicines called antiplatelet agents. It works by preventing the formation of a chemical called cyclic AMP in blood platelets. Cyclic AMP is one of the chemicals that cause platelets to clump together and start off the clotting process. Stopping its production therefore reduces the likelihood of clots forming in the blood.
Clots in the blood can cause several problems, including cutting off the blood supply to parts of the brain. This can cause a stroke, or a mini-stroke (transient ischaemic attack). This medicine is used to prevent this in patients who are at risk.
What is it used for?
Prevention of further mini-strokes (transient ischaemic attacks) in people who have already had one
Prevention of further strokes in people who have already had a stroke
Warning!
You should consult your doctor if you are considering taking aspirin to reduce the risk of suffering a stroke or heart attack, to make sure it would be a suitable thing for you to do. Aspirin can actually increase the risk of a particular type of stroke in certain people, and it may also have side effects that outweigh its potential benefits for some people.

Pregnancy and Breastfeeding
Certain medicines should not be used during pregnancy or breastfeeding. However, other medicines may be safely used in pregnancy or breastfeeding providing the benefits to the mother outweigh the risks to the unborn baby. Always inform your doctor if you are pregnant or planning a pregnancy, before using any medicine.
This medicine should be used with caution during the 1st and 2nd trimesters. Seek medical advice from your doctor. It should not be used in the 3rd trimester as it can delay or prolong labour and increases the risk of bleeding.
This medicine may pass into breast milk in small amounts. It should only be used during breastfeeding if the benefit to the mother outweighs any potential risk to the nursing infant. Seek medical advice from your doctor.
