Drug treatment of inflammatory joint disease Flashcards
(27 cards)
What is the main difference between osteoarthritis and rheumatoid arthritis?
Osteoarthritis is a degenerative joint disease, while rheumatoid arthritis is a chronic inflammatory autoimmune disease.
What is the prevalence of rheumatoid arthritis worldwide?
0.8%.
In which demographic is rheumatoid arthritis 3-5 times more common?
Females.
What is the typical age range for the onset of rheumatoid arthritis?
30-55 years old.
What is a common consequence of rheumatoid arthritis for patients 2-3 years after onset?
~20-30% patients unable to work.
What is ‘pannus’ in the context of rheumatoid arthritis?
Abnormal fibrovascular tissue.
What are the two main treatment goals for rheumatoid arthritis?
- Control pain/symptoms
- Treat disease progression.
What medications are commonly used to control pain and symptoms in rheumatoid arthritis?
- Paracetamol
- NSAIDs.
What types of drugs are used to reduce inflammation in rheumatoid arthritis?
- NSAIDs
- COX-2 inhibitors
- Glucocorticoids.
What are DMARDs in the context of rheumatoid arthritis?
Disease Modifying Anti-Rheumatic Drugs.
Distinguish between xenobiotic and biological DMARDs.
- Xenobiotic DMARDs: synthetic drugs
- Biological DMARDs: derived from biological sources.
Name a common NSAID used for rheumatoid arthritis.
- Ibuprofen.
What is the mechanism of action of glucocorticoids?
Powerful anti-inflammatory and immunosuppressive effects.
True or False: Glucocorticoids alter disease progression in rheumatoid arthritis.
False.
What is the role of glucocorticoids in rheumatoid arthritis treatment?
Bridge therapy to control symptoms until DMARDs are effective.
What is the primary action of COX-2 inhibitors?
Reduce inflammation with fewer gastrointestinal side effects.
What is a notable side effect of COX-2 inhibitors?
Increased risk of cardiovascular events.
What is the common first choice DMARD for rheumatoid arthritis?
Methotrexate.
What is the mechanism of action of methotrexate?
Folate antagonist targeting dividing cells.
List common side effects of methotrexate.
- Mucosal ulceration
- Hepatic toxicity
- Renal toxicity
- Skin reactions
- Nausea.
What is the active component of sulfasalazine that helps reduce inflammation?
5-aminosalicylic acid (5-ASA).
What role do biological agents play in rheumatoid arthritis treatment?
Target specific signaling pathways between immune cells.
What is the target of rituximab in rheumatoid arthritis?
CD20 on B cells.
What happens when TNF inhibitors fail in rheumatoid arthritis treatment?
Consider switching to rituximab or other biological agents.
