normal tissues, GI tract, kidneys, platelets
Where are COX2 receptors expressed
not normally present, but are induced to inflammatory stimuli
What does the stimulation of COX2 result in?
prostaglandins that activate and sensitize nociceptors
Indications for non-opioid analgesics? like COX1 and COX2 inhibitors?
effective for somatic pain, muscle/joint, bone/dental, inflammatory, postop
Benefits of using celecoxib?
does not inhibit platelet aggregation, less likely to cause GI distress

What drugs are in the salicylate class?
aspirin, diflunisal (dolobid), CMT (choline magnesium trisalicylate), trolamine salicylate (lotion/cream)

What drugs are considered propionic acid derivative class? (5)
ibuprofen (advil, motrin), naproxen (aleve), ketoprofen, flurbiprofen, oxaprozin
Benefits of ibuprofen vs other NSAIDS
less GI effects
What are the special indications for naproxen?
RA, OA, ankylosing spondylitis, juvenile arthritis, gout, dysmenorrhea (primary)
