Exam 1 Medication Flashcards
Types of analgesics
NSAIDs (1st and 2nd gen), acetaminophen, opioids, centrally acting nonopioids
COX (Cyclooxygenase)
produces inflammatory response
enzymes convert arachidonic acid into prostaglandins and other compounds
COX-1
homeostasis
protects gastric mucosa, enhance platelet aggregation, promotes renal function
COX-2
response to injury
inflammation, pain, fever
1st gen NSAID Pharm Action
COX-1 and COX-2 inhibitor
decrease: pain, inflammation, temp
anticoagulant, impairs renal perfusion, gastric mucosa not protected
Types of 1st gen NSAIDs
aspirin (ASA), ibuprofen (Advil, Motrin), naproxen, aleve, indomethacin, ketorolac
1st gen NSAIDs ADR
gastric upset, heartburn, nauseas, gastic ulcers, bleeding tendencies, renal dysfunction, Reye’s syndrome (swelling in liver and brain in kids after viral infection)
1st gen NSAIDs Interventions
monitor s/s of bleeding and easy bruising petechiae,
may need to use proton pump inhibitor,
monitor I&O,
do labs: BUN and creatine,
monitor tinnitus, dizzy, headache
abd pain, hematemesis, coffee-ground emesis
red, black or tar stool

celecoxib (Celebrex)
2nd Gen NSAIDs Pharm Action
COX-2 inhibitor, suppress pain inflammation and fever, decrease gastric effects, increase risk for CV issues (vasoconstrictor and platelet aggregation)
2nd Gen NSAIDs Intervention
monitor s/s of GI bleed may need proton pump inhibitor monitor I&O monitor lab: BUN, creatine monitor s/s for MI (left arm hurt, impending doom, jaw pain) and CVA (slur speech, face droop)
