Which medication is a non-steroidal anti-inflammatory drug (NSAID)?

Celebrex is classified as a non-steroidal anti-inflammatory drug (NSAID) and is specifically designed to relieve pain, reduce inflammation, and lower fever. As an NSAID, it works by inhibiting enzymes in the body called cyclooxygenases (COX-1 and COX-2), which play a crucial role in the production of prostaglandins. Prostaglandins are compounds that contribute to inflammation, pain, and fever. By reducing the synthesis of these compounds, Celebrex can effectively alleviate various types of pain, including that associated with arthritis.

In contrast, the other medications listed serve different purposes. Flexeril is a muscle relaxant typically used to treat muscle spasms. Ambien is a sedative primarily prescribed for the treatment of insomnia. Adderall is a stimulant used to treat attention deficit hyperactivity disorder (ADHD). None of these drugs possess the anti-inflammatory properties associated with NSAIDs, making Celebrex the only appropriate choice in this context.
