Module 6: Bone & Joint Disorders Flashcards
Osteoar_______:

Osteoarthritis
Osteoa________:
Non-pharmacological approaches include Rest, Weight loss (if overweight), Exercise (low impact, aerobic, strength training), Heat / Ice, Occupational/physical therapy (OT/PT) and Surgery
Osteoarthritis
A___:
First line therapy for mild to moderate osteoarthritis
(Recognized by American College of Rheumatology, European League Against Rheumatism, Academy of Orthopedic Surgeons)
APAP
A___: First line therapy for mild to moderate osteoarthritis.
- 325 to 650 mg by mouth every 4 to 6 hours
- 4 g per day
- 2-3 g per day, if patient is >75 years (also recommended by some clinicians for the general population to reduce the risk of hepatic injury) (AGS 2009)
- 2 g per day, if heavy alcohol use, malnutrition, fasting, low body weight, advanced age, febrile illness, select liver disease, and use of drugs that interact with acetaminophen metabolism may increase risk of hepatotoxicity (Hamilton 2019b; Hayward 2016; Larson 2007).
APAP
Regarding A___ and OA:
A common reason for inadequate response is failure to use sufficient dose for adequate duration (4-6 week). Some patients may require scheduled (ATC) dosing vs PRN dosing
APAP
Regarding OA:
A___ should be tried initially at an adequate dose and duration before considering an NSAID.
APAP
A___ is considered as effective as NSAID for mild-moderate OA pain
APAP
Regarding A___ and OA:
Consider alternative pharmacologic therapy if inadequate response or in presence of severe pain and/or inflammation, based on relative efficacy and safety, as well as concomitant medications and comorbidities
APAP
N_____ for OA:
a reasonable adjunct or alternative therapy when APAP fails to provide an acceptable analgesic response (despite adequate dose / duration / ATC dosing) or if there is an inflammatory component. ACR conditionally recommends use of oral N____s as an option for the initial management of moderate-severe OA.
NSAIDs
All N_____ (regarding OA) are equally effective when used at comparable doses.
NSAIDs
Regarding OA:
selection of a specific oral N____ should be based on patient preference, previous response, tolerability, side-effect profile, dosing frequency, cost, and underlying GI risk.
NSAID
Regarding N____s and OA:
use lowest effective dose and avoid long-term use if possible
NSAID
Regarding OA:
C__-2 i_________ are equally effective, but no more effective than non selective NSAIDs and should be reserved for those at high risk for GI events.
COX-2 inhibitors
Regarding OA:
Gastroprotection or COX2:
- Cox2 inhibitors may be associated with increase CV risk
- Non-selective N____s such as diclofenac also have increased CV risk vs other non-selective N____s
NSAIDs
Regarding OA and N_____:
Acetaminophen in combination with low-dose naproxen or ibuprofen could help to control pain and reduce GU risk.
NSAIDs
Regarding OA:
- use N_____ (including nonselective and COX-2-selective agents) with caution if cardiovascular risk factors are present
NSAIDs
Regarding OA:
Glu________ and chon_______:
In the landmark GAIT trial sponsored by NIH, the use of this was no more effective than placebo in decreasing pain. However, in the context of study limitations, there may be a modest reduction in pain and improved mobility in some patients. They may also slow disease progression, although the clinical impact is unclear at this time.
- Can be extrapolated to other remedies such as turmeric (curcumin), white willow bark, MSM, SAMe
- As over the counter supplements, it is important to note that they are not regulated by the FDA
Glucosamine and chondroitin
Regarding Intraarticular Injections and O_:
- May be considered as an option in the initial management (ACR conditional recommendation), especially in patients with moderate-to-severe pain refractory to oral analgesic/anti-inflammatory agents
OA
Regarding intraarticular injections and O_:
Corticosteroids:
Onset in days, but duration does not persist for beyond 4 weeks. Safe frequency of injection is not an absolute number but varies according to the risk to chondrocyte viability and cartilage depth inherent to each disease. Serial injections (every three months) are discouraged due to potential negative effects on the progression of cartilage damage in knee OA patients
- The use of systemic corticosteroids is discouraged in OA
OA
Regarding intraarticular injections and O_:
Hyaluronic acid:
- Viscous substance believed to facilitate joint lubrication and shock absorption
- Effect persists for longer than the residence time in the synovium
- Greater pain relief than corticosteroids, but longer time to onset
OA
Regarding O_:
Tramadol / Opioids - Reserved for moderate or severe pain which impairs function or quality of life, for which potential benefits outweigh risks, and for which no alternative has better risk/benefit profile, patients unresponsive to other therapies or when other therapies are contraindicated
OA
Regarding Ost__a_______s and pain:
- Opioids (including tramadol) should be initiated with short-acting agents at low doses and titrated to the lowest effective dose
- Opioids (including tramadol) should be combined with acetaminophen or NSAIDs to reduce the opioid requirement
- Clinicians should establish realistic pain and function goals
- response to opioid therapy should be assessed within 1 to 4 weeks of initiation or dose increase and every 3 months thereafter
OA
Tram____ (med, regarding OA):
weak μ receptor agonist, serotonin re-uptake inhibitor, nor-epinephrine re-uptake inhibitor
- Increase seizure risk
- Serotonin syndrome

S___ (duloxetine) - FDA approved for the management of chronic musculoskeletal pain, including OA
SNRI
Regarding dul_______ (SNRI) and OA pain:
May be of benefit in those with concomitant neuropathic pain

- geriatric patients may be at greater risk for clinically important hyponatremia
- urinary hesitation and urinary retention have been reported
- orthostatic hypotension reported, especially within first week of therapy
- Concomitant use with tramadol should be pursued cautiously owing to an increased risk of serotonin syndrome.

osteoporosis
Regarding osteoporosis:
Bisph_________s: Of the antiresorptive agents, these consistently provide greatest fracture risk reduction and BMD increases.
- ≈ ½ of absorbed drug accumulates in bone, Remainder of absorbed drug eliminated renally.
Bisphosphonates
Regarding osteoporosis and B______________:
Select CIs/ADRs:

Bisphosphonates
Regarding o___________:
Estrogens/HRT:
Estrogen deficiency is associated with a gap between bone resorption and bone formation. While there are multiple possible mechanisms for this, estrogen effects on decreasing osteoblast apoptosis, oxidative stress, and osteoblastic NF-κB activity appear to be key mediators of the ability of estrogen to maintain bone formation.
osteoporosis
Regarding o____p______:
Estrogen/hormone therapy is approved by the FDA for the prevention of this, relief of vasomotor symptoms, and vulvovaginal atrophy associated with menopause.
Refer back to Men’s/women’s health. Estrogen must be used in combination with a progestin for women with an intact uterus
osteoporosis

osteoporosis
Regarding osteoporosis and the use of estr____ as treatment:
The study was halted early despite demonstrated reduction in fracture because it was also shown
- increase risk of heart disease
- increase risk of stroke
- increase risk of blood clots in lungs
- increase risk of breast cancer
- increased endometrial cancer
- increase in dementia
estrogen
Regarding osteoporosis:
Because of the risks, E_/H_ should be used in the lowest effective doses for the shortest duration to treat moderately severe menopausal symptoms and should be considered primarily for women within the first few years of menopause.
- lower doses of transdermal estrogen may be preferred route of administration in women who are older, or those with metabolic syndromes such as fatty liver or hypertriglyceridemia with risk of pancreatitis

- B___________ component reduces the risk of endometrial hyperplasia that can occur with the estrogen. Therefore progestins do not need to be taken
- See estrogen precautions
- Like other products containing estrogen, it should be used for the shortest duration consistent with treatment goals and risks for the individual woman.
- When using this drug only for the prevention of osteoporosis, such use should be limited to women who are at significant risk of osteoporosis and only after carefully considering alternatives that do not contain estrogen.
Conjugated estrogens/Bazedoxifene:
Calc______:
FDA approved for the treatment of osteoporosis in women who are 5 years past menopause
