Q

Anti-inflammatory effect of glucocorticoids is caused by

Study These Flashcards
A
  • Reducing the prostaglandin and leukotriene which results from inhibition of phospholipase A2
  • Reducing macrophages migration into the site of inflammation
  • Decreasing capillary permeability
23
Q

True or False about anti-inflammatory effect of glucocorticoids. Anti-inflammatory effect of glucocorticoids results from inhibition of cyclooxygenase

24
Q

True or False about anti-inflammatory effect of glucocorticoids. Anti-inflammatory effect of glucocorticoids results from inhibition of phospholipase A2 and reducing prostaglandin and leukotriene synthesis

25
True or False about anti-inflammatory effect of glucocorticoids. Induction of cyclooxygenase II expression which results in reducing amount of an enzyme available to produce prostoglandins
FALSE
26
Immunosupressive effect of glucocorticoids is caused by
Reducing concentration of lymphocytes (T and B cells) and inhibiting function of tissue macrophages and other antigen-presenting cells
27
True or False about anti-inflammatory effect of NSAIDs. Anti-inflammatory effect of NSAIDs results from inhibition of cyclooxygenase
TRUE
28
True or False about anti-inflammatory effect of NSAIDs. Anti-inflammatory effect of NSAIDs results from inhibition of phospholipase A2 and reducing prostaglandin and leukotriene synthesis
FALSE
29
True or False about anti-inflammatory effect of NSAIDs. Anti-inflammatory effect of NSAIDs results from induction of cyclooxygenase II expression which results in reducing the amount of an enzyme available to produce prostoglandins
FALSE
30
Indication of glucocorticoids is
- Chronic (Addison’s disease) and acute adrenocortical insufficiency - Organ transplants (prevention and treatment of rejection – immunosuppression) - Inflammatory conditions of bones and joints (arthritis, bursitis, tenosynovitis).
31
Indications of glucocorticoids are
- Gastrointestinal diseases (inflammatory bowel disease) - Inflammatory conditions of bones and joints (arthritis, bursitis, tenosynovitis) - Skin diseases (atopic dermatitis, dermatoses, localized neurodermatitis)
32
Serious side effects of glucocorticoids include
- Acute peptic ulcers - Iatrogenic Cushing’s syndrome (rounding, puffiness, fat deposition and plethora alter the appearance of the face – moon faces) - Hypomania or acute psychosis
33
Serious side effects of glucocorticoids include
- Adrenal suppression - Insomnia, behavioral changes (primarily hypomania) - Rounding, puffiness, fat deposition and plethora alter the appearance of the face – moon faces
34
True or False. Selective COX-2 inhibitors are safer than nonselective COX-1 inhibitors but without loss of efficacy.
TRUE
35
True or False. The constitutive COX-2 isoform tends to be homeostatic in function, while COX-1 is induced during inflammation and tends to facilitate the inflammatory response.
FALSE
36
Which property combinations is peculiar to the majority of NSAIDs?
Antipyretic, analgesic, anti-inflammatory
37
Which NSAIDs is a propionic acid derivative?
Ibuprofen
38
Which NSAIDs is an indol derivative?

39
Which NSAIDs is a pyrazolone derivative?
Metamizole (Analgin)
40
Which NSAIDs is a fenamate derivative?
Meclofenamic acid
41
Which NSAIDs is an oxicam derivative?
Piroxicam
42
Which NSAIDs is a selective COX-2 inhibitor?
Celecoxib
43
Which NSAIDs is a nonselective COX inhibitor
Piroxicam
44
True or False. Aspirin inhibits phospholipase A2
TRUE
45
Indication for aspirin administration are
- Inflammatory conditions - Decreasing the incidence of transient ischemic attack, unstable angina, coronary artery thrombosis with myocardial infarction, and thrombosis after coronary artery bypass grafting - Reducing elevated body temperature
46
Side effects of aspirin include
- Gastric upset (intolerance) - Salicylism (vomiting, tinnitus, decreased hearing, and vertigo) - Gastric ulcers and upper gastrointestinal bleeding
47
Serious side effects of metamizole (analgin) include
Agranulocytosis, aplastic anemia
48
Side effects of indometacin include
- Abdominal pain, diarrhea, gastrointestinal hemorrhage and pancreatitis - Dizziness, confusion and depression - Trombocytopenia
49
True or False. Ketoprofen is a propionic acid derivative that inhibits both cyclooxygenase (nonselectively) and lipoxygenase.
TRUE
50
True or False. Ketorolac is an NSAID that is promoted for systemic use as an anti-inflammatory, not as an analgesic drug.
FALSE
51
Which drugs is a 5-lipoxygenase (5-LOG) inhibitor?
