Tiaprofenic acid belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). It works by blocking the production of a chemical (prostaglandin) which the body produces in response to injury or certain diseases. This prostaglandin would otherwise go on to cause swelling, pain and inflammation. (en)
