Ibuprofen has relieved pain and inflammation for millions of people. It works, scientists believe, by controlling the body's synthesis of a hormone called prostaglandin, which affects the inflammatory response to injury, stress, or injury. Some triathletes tape the little brown pills to their bikes so they can take them as they ride. For people who tolerate vitamin I well, it's pretty much a miracle drug.
