NSAIDs Flashcards
acetylsalicycliac acid
ASA
-aspirin
propionic acid
iboprofen
naproxen
indoleacetic acid
indomethacin
etodolac
hereroaryl acetic acid
ketoralac
COX 2 selective NSAID
celecoxib
non-narcotic analgesic
acetaminophen
weak anti-inflammatory
acetaminophen
anti-inflammatory, analgesic, anti-pyretic
NSAIDs
analgesis, antipyretic
acetaminophen
NSAIDs MOA
inhibit COX - no PG synthesis
precursor to PG
arachidonic acid
free AA enters 1 of 2 pathways
- COX - PG synthesis
- lipoxygenase - leukotriene synthesis
COX1
most tissues present
housekeeping
COX2
undetectable in most tissue
increased during inflammation
irreversible inhibition of COX in platelets
aspirin
-used as anti-coag
analgesic effect
PGE2 sensitizes pain nerve endings
pyresis
cytokines, leukocytes, PGs in brain areas
vasodilation
PGE2 and PGI2
blocked by NSAIDs
apoptosis
PG inhibit apoptosis
NSAID - more apoptosis
used of NSAIDs and reduced risk of cancer
dose of aspirin for anticoag
low dose needed - 85-160mg/day
high dose aspirin
inhibit PGI2 - which is vasodilator and inhibitor of platelet
counterproductive for anticoag effect of aspirin
renal function and NSAIDs
decreased renal blood flow
decrease rate of glomerular filtration
can result - renal failure
