What is the goal of the pharmacological therapy with agents such as salicylates and NSAIDS (anti-inflammatory)?
to inhibit COX
Salicylates and most NSAIDS inhibit COX-1, COX-2, or both?
both
True/False:

There is one NSAID that selectively inhibis COX-2.
true
What is the problem with the inhibition of COX-1?
can leads to bleeding disorders through anti-platelet aggregation
_______ (COX-1 or COX-2) is protective of the stomach lining.
COX-1
Drugs that inhibit _________ are more likely to cause gastric irritation with bleeding; especially in the elderly.
COX-1
What is the advantage of selective COX-2 inhibitors?
they decrease the incidence of bleeding disorders
COX-2 selective inhibitors have been implicated in what negative disorders?
increased incidence of cardiac disorders and strokes due to edema and hypertension
Why were rofecoxib and valdecoxib, COX-2 selective inhibitors, taken off the market by the FDA?
because there was an increase in cardiac disorders and strokes associated with these drugs
What is the primary use for aspirin?
used for anti-platelet aggregation in heart disease
What specific consideration should be known about ketorolac, a potent NSAID?
- it is extremely potent, can only be used short term (5 days or less) due to a high potential for nephrotoxicity

- only NSAID that can be given parenterally
What can be caused by both NSAIDS and salicylates due to the inhibition of COX-1?
Peptic Ulcers
What should be done to avoid stomach irritation with NSAIDS and salicylates?
give with food
Many clients must take what with NSAIDS and salicylates to counter the stomach irritation?
antacids and/or histamine blockers
True/False:

You still should take antacids or histamine blockers to avoid stomach irritation even with the IV form of an NSAID.
True
Both NSAIDS and salicylates can cause what due to their anti-platelet aggregation abilities?
bleeding disorders
What effect can NSAIDS and salicylates have on the kidneys?
- both can cause vasoconstriction of the kidneys which can lead to renal damage
What can occur when a client takes salicylates in high doses?
tinnitus (ringing in the ears)
What is a nursing consideration for a client with asthma and on salicylates?
- they can cause bronchospasm with wheezing, especially in clients with asthma
Why should children who have viral infections avoid the use of salicylates?
it can lead to the potentially fatal Reye Syndrome
Edema may be caused by the use of NSAIDS. What might this lead to?
hypertension
True/False:

NSAIDS and Salicylates work on inflammation relatively quickly, decreasing inflammation in a few hours.
False- normally it takes days or weeks to reduce inflammation
The use of herbs (dong quai, feverfew, garlic, ginger, and ginkgo biloba) along with NSAIDS and Salicylates, can increase the risk for what?
bleeding disorders
Corticosteriods are examples of what drug class?
immunosuppressant drugs
Corticosteroids are hormonal substances produced by what?
the adrenal cortex
The levels of corticosteroids naturally in the body will rise in response to what?
physical or psychological stress
What 3 things can exogenous corticosteroids decrease?
1. decrease inflammation
2. decrease the allergic response
3. decrease the symptoms caused by an auto-immune disease
How do corticosteroids decrease inflammation?
they suppress the immune system
Corticosteroids penetrate cell membranes and bind to what?
intracellular corticosteroid receptors
The # of what is reduced in the blood when there is a higher # of corticosteroids?
The number of circulating lymphocytes, basophils, and monocytes
True/False:

Phagocytosis is enhanced with the use of corticosteroids.
False- it is inhibited
What is the largest concern with the use of corticosteroids?
- the suppression of the immune system
What drug class has a mechanism of action that can predispose the body to infection, decrease the ability to fight infection, and mask the signs and symptoms of infection?
corticosteroids
In addition to inhibiting phagocytosis, corticosteroids also inhibit the release of what 3 things?
- histamines
- leukotrienes
- prostaglandins
True/False:

Corticosteroids work quickly and are very effective.
True
Why are corticosteroids generally only for short term use?
