Carprofen acts primarily as which of the following?

Carprofen acts primarily as which of the following?

• A. COX-1 inhibitor
• B. COX-2 inhibitor
• C. Paracetam receptor agonist
• D. Monoamine oxidase inhibitor

Answer: (B)

Carprofen is an NSAID that acts primarily by inhibiting the cyclooxygenase-2 (COX-2) enzyme. Inflammation boosts COX-2 activity, leading to production of prostaglandins that drive pain and swelling. By preferentially blocking COX-2, carprofen reduces prostaglandin synthesis at inflamed sites, delivering analgesic and anti-inflammatory effects with a lower impact on COX-1, which helps protect the stomach and support platelet function. The other options don’t describe the drug’s action: there is no “paracetam receptor” that carprofen targets, and monoamine oxidase inhibitors are unrelated to how NSAIDs relieve inflammation and pain.
