NSAIDS Flashcards
Type of NSAIDs
Non-selective NSAIDs
Cox-2 selective NSAIDs
Non-selective NSAIDs
Acetylsalicylic Acid (Aspirin)
Ibuprofen
Naproxen
Ketorolac
Cox-2 Selective NSAIDs
Celecoxib
NOT an NSAID
Acetaminophen
Acetaminophen
Pain reliever
Fever reducer
NSAIDs control what?
Mild to moderate pain
What kind of properties of NSAIDs
Analgesic (reduce pain)
Antipyretic (reduce fever)
Anti-inflammatory properties
Conditions to use NSAIDs
HA
Fever
Arthralgia
Myalgia
RA
OA
CV applications
Prophylactic use of low dose aspirin reduces risk of stroke and death from acute MI, stable and unstable angina
Acute pain
Temporary in nature
Usually goes away when cause of pain has been resolved
Chronic pain
Neuropathic pain
Results from nerve damage
Last for months
Often refractory to treatment
Inflammation
Body’s natural response to protect itself against the injurious agent
Inflammation is characterized by
Pain
Heat
Redness
Swelling
Loss of function (when chronic)
Analgesia
Insensibility to pain w/out a loss of consiousness
Nociceptor
Sensory receptor (pain receptor) that provides informatin about noxious input
Hyperalgesia
Increase sensitivity to noxious stimuli
Allodynia
Exaggerated pain response to a normally non-noxious stimulus (light touch, bed sheets, clothing, etc.)
NSAIDs
- periphery
Control mild to moderate pain
NSAIDs
- centrally
Hypothalamus
Reduce fever
What released following tissue damage
Potassium (K+)
Prostaglandins (PG)
Bradykinin (BK)
Prostaglandins
Increase sensitivity of the sensory nerve terminal to bradykinin and other pain-producing substances
Prostaglandins
- sensitize pain receptors to mechanical and thermal stimuli
By lowering the threshold of C-polymodal nociceptors
Induces the release of substance P
Impulses generated in the stimulated terminal propagate not only to the SC, but also to the terminal branches
At the blood vessels what does substance P do
Vasodilation and neurogenic edema
What releases d/t SP
Histamine (H) from mast cells
Serotonin (5-HT) from platelets
What do histamine and 5-HT do?
Raise the levels in the extracellular space causing secondary sensitization of nearby nociceptors
Histamine and 5-HT
- Secondary sensitization
Gradual spread of hyperalgesia and/or tenderness
