Arcoxia is a prescription medication known generically as etoricoxib, which belongs to a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs), specifically within the subgroup known as selective COX-2 inhibitors. It is primarily used for the treatment of various forms of arthritis, including osteoarthritis, rheumatoid arthritis, and gouty arthritis, as well as for the relief of chronic musculoskeletal pain, acute pain, and to alleviate discomfort associated with dental surgery. Arcoxia works by selectively inhibiting the enzyme cyclooxygenase-2 (COX-2), which plays a key role in the inflammation process, thereby reducing pain and swelling. Unlike traditional NSAIDs, its selective action minimizes the risk of stomach ulcers and gastrointestinal bleeding, making it a preferred option for patients requiring long-term pain management. However, like all medications, it comes with potential side effects and risks, and its use should be closely monitored by a healthcare professional.
