In spite of its age and competition from newer pain relievers that tout fewer side effects, its value continues to mount. In addition to relieving pain, aspirin is known to decrease swelling and bring down fever. It was the first drug in the class of nonsteroidal anti-inflammatory agents. One of its competitors in this class of drugs is ibuprofen. Aspirin seems to have unique effects on platelets, a type of blood cell that helps stop bleeding.
Platelets work with other substances to form clots where blood vessels are but.
Blood clots are necessary when someone cuts himself. However, they are not helpful when they travel through the body. The result can damage the heart, the lungs, the brain and other organs. When a blood clot travels the body, it can lodge in smaller vessels and keep oxygenated blood from going further. This is perceived as pain.
