Aspirin is known as a salicylate and a nonsteroidal anti-inflammatory drug (NSAID) that works by blocking a certain natural substance in your body to reduce pain and swelling.
Aspirin is also used in low doses as a blood thinner to prevent blood clots after surgery on clogged arteries (e.g., bypass surgery, carotid endarterectomy) and to reduce the risk of stroke or heart attack.
