Definitions related to ketorolac tromethamine:
-
A pyrrolizine carboxylic acid derivative structurally related to INDOMETHACIN. It is a non-steroidal anti-inflammatory agent used for analgesia for postoperative pain and inhibits cyclooxygenase activity.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
The tromethamine salt of ketorolac, a synthetic pyrrolizine carboxylic acid derivative with anti-inflammatory, analgesic and antipyretic properties. Ketorolac tromethamine, a non-selective inhibitor of the cyclooxygenases (COX), inhibits both COX-1 and COX-2 enzymes. This agent exerts its anti-inflammatory effect by preventing conversion of arachidonic acid to prostaglandins at inflammation site mediated through inhibition of COX-2, which is undetectable in most tissues but is up-regulated at the inflammation sites. Since COX-1 is expressed virtually in all tissues, inhibition of COX-1 enzyme by this agent prevents normal state production of prostaglandins, which plays housekeeping roles in the protection of the gastrointestinal tract, regulating renal blood flow, and functioning in platelet aggregation. As a result, inhibition of COX-1 is usually associated with adverse effects such as gastrointestinal toxicity and nephrotoxicity.NCI ThesaurusU.S. National Cancer Institute, 2021
