Q

What is the function, use, and precaution for treatment with acetaminophen

A

Function: decrease pain, reduce fever
Use: 1st line for OA, control of mild to mod joint pain. 1-2 hours to take effect
Precautions: Tolerated better than NSAIDS and safe in elderly with comorbidities. Safe to take in combo with NSAID or other arthritis meds. Risk of liver failure if too much or in combo with alcohol

20
Q

What is the function, use, and precaution for treatment with NSAIDS

A

Function: Decrease pain, swelling, stiffness, fever
Use:
- Primariy is OA, spondylitis for joint pain + inflammation.
- High NSAID intake slows new bone formation in individuals with hight c-reactive protein only
- Analgesia 30-60mins, steady state after 2 days
- Few days 1/week for optimal anti-inflammatory effects
Precautions:
- Raises BP
- Increased cardiovascular event risk (non-aspirin NSAIDS), but the risk is lower than smoking or hypertension
- Make sure not combining 2 types together
- Topical have similar benefits and safer

21
Q

What are some types of NSAIDS

A

Aspirin, ibuprofen, naproxen

22
Q

What is the function, use, and precaution for treatment with Serotonin-norepinephrine reuptake inhibitory

A

Function: Second-line analgesis agen where no/partial response to acetaminophen/NSAIDs. Takes effect within 1 week
Use: neuropathic pain in OA
Precations: Side effects include dizziness/light headedness. may raise BP

23
Q

What is the function, use, and precaution for treatment with Opioids

A

Function: Decrease pain
Use:
- Second line Rx for moderate to severe OA pain; not commonly used as often risk>benefit
- No data on benefit for inflammatory arthritis past 6 weeks
- work within 1 hour
Precautions:
- Side effects can include drowsiness, dizziness, constipation
- Opioid tolerance with prolonged use can sensitize to pain
- Risk of dependence with chronic use

24
Q

What are opioids prescribed for

A
  • Acute/chronic pain resulting from disease, surgery or injury
  • Moderate to severe coughs & diarrhea
  • To treat addiction to other opioids such as heroin or oxycodone
  • Controlling pain in terminal illness
25
Q

What can long-term use of opioids lead to

A
  • Increased tolerance to the drug, so that more needed to produce same pain relieving effect
  • Dependence
  • Withdrawal symptoms
26
Q

What are the 1st and 2nd lines of treatment for disease modifiers

A

1st - DMARDS

2nd - Biologics

27
Q

What are adjuncts to treatment with disease modifiers

A

Corticosteroids
Analgesics
NSAIDS

28
Q

What is the function, use, and precaution for treatment with DMARDs (Methotrexate)

A

Function: Disease modifying anti-rheumatic drug. Prevent joint damage by suppressing inflammatory pathways. Can take up to 3 months for full effect
Use: IA: RA, juvenile idiopathic arthritis, psoriatic arthritis, lupus
Precautions: Side effects can include nausea and faitgue day after with methotraxate

29
Q

What can improve the fatigue and nausea felt with methotrexate

A

Taking folic acid

30
Q

What are the two ways you can take methotrexate

A

oral tablets

subcutaneous injection

31
Q

What is the function, use, and precaution for treatment with biologics

A

Function: Same as DMARDs; reserved for people who have not responded adequately to conventional DMARDs and for those who cannot tolerate DMARDs in doses large enough to control inflammation
Use: RA, axial spondylitis, etc.
Precautions:
- Increased risk of serious infections
- Sterile technique if dry needling, keep environment hygienic

32
Q

Are biologics simple or complex proteins

A

complex

33
Q

Are biologics more or less variable than chemically synthesized drugs

A

more

34
Q

What is a biosimilar

A

a copy of a biologic medicine that is similar, but not identical to the original medicine

35
Q

What is the criteria to be called a biosimilar

A

Need to demonstrate structural and functional similarities with comparable pharmacokinetic and pharmacodynamic properties to the reference product (in terms of safety, purity, potency, efficacy)

36
Q

When do biosimilars enter the market

A

Subsequent to a previously autorized version whose patent has expired

37
Q

What is the function, use, and precaution for treatment with corticosteroids

A

Function:
- Most efficacious anti-inflammatory drug available
- Oral takes effect within 1-4 days
- Injections 24-48hours rest joint
Use:
- OA - joint injection
- Inflammatory art - oral; injection
Precautions (>2months oral use:)
- Decrease bone density & risk of fracture with long term use
- Increase blood sugars
- Increase muscle wasting
- Increase infection risk
- Small risk of avascular necrosis
- Dont combine with alcohol or large amounts of NSAIDS
- Risk of GI ulceration

38
Q

What is the relationship between corticosteroids and tendon ruptures

A
  • IN vitro corticosteroids can decrease cell proliferation and collagen synthesis, collagen disorganization & necrosis
  • BUT, underlying tendinopathy, mechanical failure, cartilage erosion often already present in inflammatory arthritis and OA
  • if dont control joint or tendon inflammation, risk of joint damage/tendon rupture
39
Q

Are corticosteroids injected right into the tendon

A

no

40
Q

is acetaminophen most commonly used for OA, RA, or AxSpA?

A

OA

Can use for RA as well

41
Q

are NSAIDs most commonly used for OA, RA, or AxSpA?

A

OA and AxSpA

Can also use for RA

42
Q

are corticosteroids most commonly used for OA, RA, or AxSpA?

A

RA

43
Q

are Conventional DMARGS most commonly used for OA, RA, or AxSpA?

A

RA

44
Q

are Biologics/biosimilar DMARDs most commonly used for OA, RA, or AxSpA?

A

RA and AxSpA

45
Q

Are corticosteroid intra-articular injections most commonly used for OA, RA, or AxSpA?

A

OA
RA
and AxSpA in Si joint and peripheral joints
