Cylabrex is a brand name for the drug celecoxib, which is a nonsteroidal anti-inflammatory drug (NSAID) primarily used to relieve pain and inflammation associated with conditions such as Arthritis, menstrual pain, and other acute pain. It works by inhibiting the enzyme cyclooxygenase (COX-2), which plays a key role in the production of inflammatory substances in the body. Cylabrex is often preferred for its lower risk of gastrointestinal side effects compared to traditional NSAIDs. As with any medication, it should be used under the guidance of a healthcare professional.
