In a quest to develop a compound with antiinflammatory properties equivalent to corticosteroids but chemically nonsteroidal, Dr. Stewart Adams discovered and developed 2-(4-isobutylphenyl) propionic acid, now known as ibuprofen, and in the process created a new class of drugs designated as nonsteroidal antiinflammatory drugs (NSAIDs).35 Ibuprofen was initially marketed in the United Kingdom in 1969 and was introduced to the US market in 1974. Ibuprofen became available without a prescription in the United States in 1984.
