  1. Aspirin(n.)

    A white crystalline compound, acetyl salicylic acid (CH3.CO.O.C6H4.CO.OH) widely used as a drug for relief of pain and alleviation of fever. It has analgesic, antipyretic, and antiinflammatory properties, and is one of a class of agents called non-steroidal antiinflammatory drugs (NSAIDs). The name was originally a trade name, but has become the preferred name for the substance. It is actually a prodrug, liberating salicylic acid, the ultimate pharmacologically active agent, in the intestines. It is more effective when taken orally than is salicylic acid, because it dissolves more readily.

  1. Aspirin

    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 was first isolated by Felix Hoffmann, a chemist with the German company Bayer in 1897. Salicylic acid, the main metabolite of aspirin, is an integral part of human and animal metabolism. While in humans much of it is attributable to diet, a substantial part is synthesized endogenously. 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 damaged walls of 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 of 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. Aspirin may be effective at preventing certain types of cancer, particularly colorectal cancer.

  1. Aspirin

    The prototypical analgesic used in the treatment of mild to moderate pain. It has anti-inflammatory and antipyretic properties and acts as an inhibitor of cyclooxygenase which results in the inhibition of the biosynthesis of prostaglandins. Aspirin also inhibits platelet aggregation and is used in the prevention of arterial and venous thrombosis. (From Martindale, The Extra Pharmacopoeia, 30th ed, p5)
