Q

Differentiate between COX1 and COX2

A

COX1 - constitutive, wide distribution, homeostatic functions (platelets, GI, renal)
COX2 - expression is stimulus-dependent, facilitates inflammatory response

Q

Describe how aspirin is an irreversible inhibitor

A

Aspirin acetylates serine group, obstructing AA access → Irreversible block of cyclooxygenase → prevents platelet activation by TXA2
- lasts as long as platelets do (8-10 days)

Aspirin can cause ________ poisoning

A

salicylate

19
Q

Why should NSAIDs be avoided in pregnancy? What medication is the alternative?

22
Q

NSAIDs that are COX-2 selective have fewer _______ effects

A

GI

23
Q

What is the black box warning for celecoxib?

A

2

30
Q

Aspirin has a vaso_____ effect in peripheral tissues, but a vaso_____ effect in the CNS

A

dilation, constriction

31

  • Dexamethasone (longer acting)
34
Q

What are the indications for glucocorticoid use?

A
  • Suppression of inflammation
  • Addison’s Disease
  • Post-adrenalectomy (Cushing’s disease)
  • Fetal lung maturation
35
Q

A

Rituximab

38
Q

Biologic DMARD that is anti-TNF-α

A

Adalimumab

39
Q

Chronic exposure to inflammatory mediators leads to increased:

A
  • Cell proliferation
  • Mutatgenesis
  • Oncogene activation
  • Angiogenesis
40
Q

Describe tumor-promoting inflammation

A

Initiation: Inflammatory response increases mutational rates
- Inflammatory cells emigrate to tumor cells
- ROS accumulation
Promotion: Cytokines activate transcription factors (NF-kB / STAT3) in premalignant cells
