Ibuprofen
Sorry, this answer is incorrect. However Ibuprofen is also a very common painkiller. It was discovered in 1969 by the Pure Boot Drug Company. Ibuprofen is part of many popular drugs like Advil, Motrin, and Nuprin. Ibuprofen is a very good anti-inflammatory drug because as a cyclooxygenase inhibitor it slows down prostaglandin synthesis. This drug is used for relieving minor symptoms such as headaches, backaches, arthritis, and body pain. This substance has recently been studied as a potential treatment for Alzheimer's disease.
