Aspirin
Aspirin is commonly used as a painkiller, but it also lowers the risk of a blood clot forming in the arteries of the heart (coronary arteries) or brain, which in turn lowers the risk of having a myocardial infarction (heart attack) or stroke. It belongs to a group of drugs called non-steroidal anti-inflammatories. Low dose aspirin reduces the 'stickiness' of blood cells called platelets, which are tiny particles in the blood that help form a clot when a blood vessel is cut.
