| Question | Answer |
|---|---|
| Ibuprofen, naproxen, indomethacin, ketorolac | reversibly inhibit cyclooxygenase (both COX-1 and COX-2). Block prostaglandin synthesis |
| Ccelecoxib | reversibly inhibit COX-2 isoform found in inflammatory cells and vascular endothelium and mediates inflammation and pain; spares COX-1 which helps maintain the gastric mucosa, no corrosive affects of other NSAIDS on GI lining |
| Acetaminophen | reversibly inhibits cyclooxygenase, mostly in CNS, inactivated peripherally |
| Etidronate, pamidronate, alendronate, risedronate | inhibit osteocalstic activity; reduce both formation and resorption of hydroxyapatite |
| Colchicine | binds to and stabilizes tubulin to inhibit polymerization, impairing leukocyte chemotaxis and degranulation |
| Probenecid | inibits reabsorption of uric acid in PCT |
| Allopurinol | inhibits xanthine oxidase, v conversion of xanthine to uric acid |
| Etanercept | recombinant form of human TNF receptor than binds TNF |
| Infliximab | anti-TNF ab |
