Celecoxib is a non-steroidal anti-inflammatory drug that inhibits prostaglandin synthesis by inhibiting the enzyme cyclooxygenase-2, or COX-2 for short, thus acting as an anti-inflammatory. COX-2 has a specific inhibitory effect on this enzyme, so it is more selective and can be used to treat the signs and symptoms of osteoarthritis or rheumatoid arthritis. It can also be used to treat acute pain in adults, and can also be used to relieve the signs and symptoms of ankylosing spondylitis. It is important to note that when using celecoxib, attention must be paid to the attention of adverse reactions. The adverse effects of this medication need to be focused on gastrointestinal adverse effects, which may include gastrointestinal ulcers, bleeding, and cardiovascular risks, so be sure to use it under your doctor’s supervision.
