anti-inflammatory drug-C Flashcards
List the three main classes of anti-inflammatory drugs
salicylates, Non steroidal antiinflammatory drugs, corticosteroids
What is the mechanism of action for salicylates (subclass of NSAIDS)?
inhibit synthesis of protaglandins
What is the mechanism of action for NSAIDS?
inhibit synthesis of protaglandins
What is the mechanism of action for corticosteroids?
block arachidonic acid, decrease production of prostiglandins and leukotrienes
What is the funtion of cyclooxygenase-1 (COX-1)?
reduces gastric-acid secretion, promotes renal blood flow, promotes platelet aggregation
What happens when COX-1 I inhibited?
bleeding, gastric upset, reduced renal funtion
What is the purpose of COX-2?
promotes inflammation, sensitizes pain receptors, mediates fever in brain
What happens when COX-2 is inhibited?
suppression of inflammation
____________ is found in ALL body tissues, while _________ is only present at sites of injury.
COX-1, COX-2
___________ are the newest and most controversial class of anti-inflammatory drugs
COX-2 inhibitors
T or F: COX-2 inhibitors also inhibit COX-1
FALSE: Cox-2 inhibitors inhibit COX-2 only
____________ are the treatment of choice for moderate to severe inflammation.
COX-2 inhibitors
What is the only remaining COX-2 inhibitor on the market?
celebrex
What is a well-known prototype in the salicylates class?
aspirin
Aspirin works by:
treating inflammation by inhibiting both COX-1 and COX-2 (inhibiting prostaglandin synthesis)
What are some adverse reactions to aspirin?
bleeding and GI irritation, renal and hepatic toxicity
What can occur in children and teenagers with acute febrile illness who are given aspirin ?
reye syndrome
T or F: acetaminophen (tylenol) is an NSAID.
FALSE!!! Has NO anti-inflammatory action!
What are the primary drugs given to treat mild to moderate inflammation?
NSAIDS
The NSAID class includes which 3 main drugs?
aspirin, ibuprofen, COX-2 inhibitors
Prednisone is an example of a______________ which is in the ____________ class.
corticosteroid, glucocoticoid
Prednisone decreases inflammation by:
decreasing formation, release, and activity of endogenous mediators of inflammation and modifying the body’s immune response
What are some serious adverse effects of prednisone?
adrenal suppression, psychosis, hyperglycemia
T or F: Before administering a NSAID, baseline kidney and liver function tests as well as a CBC should be performed
TRUE
While a patient is on NSAIDS, a nurse should be assessing for 3 main things:
- GI bleeding 2. Changes in pain as well as reduction in temperature and inflammation 3. assess for adverse side effects such as nephrotoxicity, hemolytic anemia, salicylate toxicity
What is the mechanism of action for antipyretic drugs?
reduce fever by direct action on the hypothalamic heat-regulating center
What is the prototype drug in the antipyretic class?
acetaminophen (tylenol)
What is the primary use of tylenol?
to relieve pain and reduce fever-NO ANTI INFLAMMATORY ACTIONS!
What is an adverse effect of tylenol?
possible liver damage
