Coxib

Part of speech: noun

Definitions

  1. A class of nonsteroidal anti-inflammatory drugs that selectively inhibit cyclooxygenase-2 enzyme to reduce pain and inflammation while minimizing gastrointestinal side effects; medicinal compounds used primarily to treat arthritis and other inflammatory conditions; pharmaceutical agents designed to block COX-2 pathway to relieve symptoms with less impact on stomach lining
  2. Chemical substances belonging to a group of pain relievers targeting the enzyme responsible for inflammation and pain without extensively affecting the digestive system; drugs mainly prescribed for conditions such as osteoarthritis or rheumatoid arthritis to mitigate inflammation; selective inhibitors that act on a specific enzyme to provide relief from inflammatory ailments with reduced risk of stomach irritation
  3. Medicinal chemical agents that specifically obstruct the function of an enzyme connected to inflammation, providing analgesic and anti-inflammatory effects while protecting gastric mucosa compared to traditional anti-inflammatory drugs; treatment options frequently employed in clinical practice for inflammatory disorders; pharmacological inhibitors aimed at decreasing pain and swelling through selective enzyme blockade with fewer gastrointestinal adverse effects

Etymology: Coxib is a blend of "COX," short for cyclooxygenase, and "-ib," clipped from "inhibitor." COX is the enzyme that converts arachidonic acid into prostaglandins, the chemical messengers behind pain, fever and swelling. The name describes the drugs' target: they block that enzyme's COX-2 form. The selectivity matters because the older anti-inflammatory drugs, such as ibuprofen, block both COX-1 and COX-2. COX-1 also helps make protective prostaglandins in the stomach lining, so blocking it is what causes ulcers and bleeding. Coxibs spare most COX-1 activity, which is why they are gentler on the stomach. The "-ib" ending follows the naming pattern of enzyme inhibitors, as in celecoxib.

Synonyms: COX-2 inhibitor, anti-inflammatory drug
