DYNASTAT, known generically as parecoxib, is a nonsteroidal anti-inflammatory drug (NSAID) specifically classified as a COX-2 inhibitor. It is administered via injection and is primarily used for the short-term management of postoperative pain. Unlike traditional NSAIDs that inhibit both COX-1 and COX-2 enzymes, DYNASTAT selectively inhibits the COX-2 enzyme, which is primarily involved in the inflammation process. This selectivity aims to reduce the gastrointestinal side effects commonly associated with non-selective NSAIDs. DYNASTAT is effective in providing pain relief after surgical procedures, thereby helping patients to recover more comfortably. However, as with all medications, it should be used under the guidance of a healthcare professional to ensure its appropriateness based on individual health conditions and potential interactions with other medications.
