Management of pain and inflammation Part 2 Flashcards
Nonopioid analgesions incluse
NSAIDs (nonsteroidal anti-inflammator drugs) and Acetaminophen
NSAIDs: primary effects
-analgesic
-anti inflammatory
-antipyretic (reduce fever)
-anticoagulant
-anticancer?
(NSAAAAAIDs)
OTC (over the counter) NSAIDs
aspirin, ibuprofen, naproxen, ketoprofen
prescription NSAIDs
- Etodolac
- Fenoprofen
- Ketorolac
- Meclofenamate
- Piroxicam
- etc.
OTC vs Rx: therapeutic differences?
not really if give same relative dose
OTC vs Rx: safety differences?
not really– related to dosage
OTC vs Rx: cost differences
OTC much cheaper
NSAIDs inhibit synthesis of
prostaglandins
lipid compounds produced in cells (usually when cell is injured)
prostaglandins
NSAIDs decrease prostaglandins by inhibiting
cyclooxygenase
NASIDs inhibit
cyclooxygenase enzyme (COX) (decreaes prostaglandin synthesis)
COX enxyme: 2 primary subtypes
1) COX-1
2) COX-2
COX-1 vs COX-2: normal constituent certain cells
COX-1
COX-1 vs COX-2:synthesizes PGs to protect cells, maintain function
COX-1
COX-1 vs COX-2: induced when cell is injured
COX-2
COX-1 vs COX-2:synthesizes PGs that mediate pain, inflammation
COX-2
COX-1 vs COX-2: ex= stomach, kidneys, platelets
COX-1
COX-1 vs COX-2: ex= RA, other pathologies
COX-2
COX-2 selective drugs inhibit …
synthesis of PGs in pain, inflammation
COX-2 selective drugs spare production of beneficial PGs in…
stomach, kidney, platelets
COX-2 selective drugs may decrease pain and inflammation with…
less toxicity
