MSK/DERM Flashcards
NSAID that irreversibly inhibits cyclooxygenase (both COX-1 and COX-2)
Aspirin
Low dose (< 300 mg/day): platelet aggregation. Intermediate dose (300–2400 mg/day): antipyretic and analgesic. High dose (2400–4000 mg/day): anti-inflammatory.
Aspirin
Gastric ulceration, tinnitus (CN VIII). Chronic use can lead to acute renal failure, interstitial
nephritis, GI bleeding. Risk of Reye syndrome in children treated with aspirin for viral infection.
ASA
Causes respiratory alkalosis early, but transitions to mixed metabolic acidosis-respiratory alkalosis.
ASA
Reversibly inhibits specifically the cyclooxygenase (COX) isoform 2,
Celecoxib
helps maintain gastric mucosa.
Cox 1
found in
inflammatory cells and vascular endothelium and mediates inflammation and pain;
Cox 2
spares
COX-1, which helps maintain gastric mucosa.
Celecoxib
Spares platelet function as TXA2 production is dependent on COX-1.
Celecoxib
Ibuprofen, naproxen, indomethacin, ketorolac, diclofenac, meloxicam, piroxicam.
NSAIDS
Reversibly inhibit cyclooxygenase (both COX-1 and COX-2). Block prostaglandin synthesis.
NSAIDS
Antipyretic, analgesic, anti-inflammatory. Indomethacin is used to close a PDA.
NSAIDS
inhibit leukotriene receptor
montelukast, zafirlukast
Reversibly inhibits cyclooxygenase, mostly in the CNS
acetaminophen
inhibits chemotaxis, phagocytosis and degranulation. Also reduces formation of LTB4
colchicine
inhibit leukotriene synthesis
zileuton
inhibit phospholipase A 2
glucocorticoids (corticosteroids)
