NSAIDs Flashcards
PE: NSAIDs
analgesic, anti-pyretic, anti-inflammatory, anti-platelet
Aspirin
acetyl salicylic acid–weak acid
can displace warfarin because it binds plasma proteins
ENZYME INHIBITOR: Cox inhibitor (inhibits PG metabolism)
Dangerous to treat a viral infection in children–>leads to Reyes syndrome
anti-pyretic: lowers fever
analgesic–treats pain because of less PGs
anti-inflammatory: no PG to initiate response
anti-clotting: irreversible inhibition of COX (no thromboxane)
-stop taking this before surgery.
SE: aspirin
GI irritation (acid & decreased PG so less mucous)
Tinnitus
Don’t give to patients with clotting problems
Decreased kidney perfusion, inhibits labor, bronchospasm with asthma like effects
Acetaminophen
not an NSAID no anti-inflammatory, no anti-platelet good for pain, bad for RA less GI problems than aspirin liver damage (too much glutathione)
Treat tylenol OD–N-acetylcysteine
The NSAIDs
proprionic acid derivatives–“pro”
acetic acid derivatives–indometacin, tolmetin, sulindac
“NACs”
Cox-2 inhibitors–celecoxib
indomethacin
NSAID-acetic acid derivatives
COX inhibitor
treats ductus arteriosus
SE: thrombocytopenia
Celecoxib
SE: heartattack & stroke, affects PGI1 (vasodilator)
How do steroids act
bind cytoplasmic receptor
dimerize
migrate to cell nucleus
Alters DNA transcription
How do glucocorticoids act
induce lipocortin-1…inhibits synthesis of PGs
SE: glucocorticoids
deficiency of cortisol--addisons disease excess--cushings adrenal suppression decreased glucose uptake by muscle cells moon face, m wasting, growth inhibition, cataracts, heart attack, peptic ulcers, psychosis, involuntary laughing or crying, poor wound healing, osteoporosis
