Aspirin, also known as acetylsalicylic acid is a salicylate drug, often used as
an analgesic to relieve minor aches and pains, as an antipyretic to reduce
fever, and as an anti-inflammatory medication.
Aspirin also has an antiplatelet effect by inhibiting the production of
thromboxane, which under normal circumstances binds platelet molecules together
to create a patch over damage of the walls within blood vessels. Because the
platelet patch can become too large and also block blood flow, locally and
downstream, aspirin is also used long-term, at low doses, to help prevent heart
attacks, strokes, and blood clot formation in people at high risk for developing
blood clots. It has also been established that low doses of aspirin may be given
immediately after a heart attack to reduce the risk of another heart attack or
of the death of cardiac tissue.
