Ibuprofen is in a class of drugs called nonsteroidal anti-inflammatory drugs (NSAID) that has been relieving pain for quite a while. In fact, the first clinical trials of ibuprofen began in February 1966. After years of study, the first over-the-counter version of ibuprofen, also known as Advil, launched in the U.S. in 1984 and has been fighting tough pain ever since. Over 30 years of clinical studies prove Advil is effective on pain & fever.
NSAIDs, nonsteroidal anti-inflammatory drugs, are a group of chemical compounds that often are chemically unrelated but share therapeutic actions such as analgesic (pain-relieving) and antipyretic (fever-reducing) effects. Ibuprofen is just one drug in the NSAID class.
