musculoskeletal - pharm E4 Flashcards
what class is Aldendronate
biphosphates
biphosphates MOA
Binds permanently to surface of bones to inhibit osteoclast activity
Aldendronate indication
osteoporosis
Aldendronate SE
N/V/D
Esophageal ulceration
Aldendronate nursing considerations
do not lay down after taking d/t ulceration risk
do not take calcium (or other food/drinks) with this bc will lower bioavailability)
given 1x/wk
what class is Raloxifene
Selective estrogen receptor modulators (SERMs)
Selective estrogen receptor modulators (SERMs) MOA
Mimics estrogen by increasing bone density, inhibits bone resorption
Raloxifene indications
Preventing or treating postmenopausal osteoporosis
Raloxifene SE
Hot flashes
Leg problems
Stroke risk
Raloxifene nursing considerations
Safer than a hormone replacement, less affective the biphos
BBW: stroke risk
Need to take adequate calcium & vit D for this to work
Discontinue at least 72 hrs before planned procedures
Do not smoke or drink
Do not take if pregnant
what class is Calcitonin Salmon
calcitonin
Calcitonin Salmon MOA
Inhibits bone removal by osteoclasts
Calcitonin Salmon indication
Treatment of osteoporosis
Calcitonin Salmon SE
Nasal irritation
Calcitonin Salmon nursing consideration
Have to take for 5 years to see long term benefit
Slows done bone loss and increases spinal bone density
Given intranasal
what class is Methotrexate
DMARD ; antineoplastic, anti-rheumatic
Methotrexate MOA
Immunosuppressive -> interferes w/ folic acid metabolism
Methotrexate indication
RA
Methotrexate SE
GI
Bone marrow suppression
Shortened life expectancy
Methotrexate nursing consideration
Need folic acid replacement
1x/wk or deadly
Hepatotoxic -> monitor liver enzymes
Monitor RBCs & WBCs
11 BBW
-no alcohol
-teratogenic (need BC)
-high infection risk
-liver & kidney disease
-aplastic anemia w/ NSAID use
what class is Hydroxychloroquine
DMARD; antimalarial, anti rheumatic
Hydroxychloroquine MOA
Unknown but anti inflammatory processes
Hydroxychloroquine indications
RA
Hydroxychloroquine SE
Retinopathy
Hydroxychloroquine nursing considerations
Less side effects than methotrexate, Slow progression of RA when used in combo w/ other DMARDs
what class is Biologic Agents
New generation DMARDs
Biologic Agents MOA
Targets part of the immune system that triggers inflammation that causes joint and tissue damage
Biologic Agents indication
RA
Biologic Agents SE
Increase risk of severe skin or lung infections, skin cancers, serious allergic rx
Biologic Agents nursing considerations
Usually given w/ methotrexate
what class is Allopurinol
Xanthine oxidase inhibitor
Xanthine oxidase inhibitor MOA
Inhibits the xanthine oxidase enzyme, which prevents uric acid production
Allopurinol indications
Gout related to excess uric acid production
Allopurinol SE
Agranulocytosis
aplastic anemia
fatal skin reaction -> can cause Steven Johnson syndrome which can leads to TENs
Allopurinol nursing considerations
Prevention drug
May cause hypoglycemia -> watch sugars
If on warfarin, monitor INR closely
Onset is 2-6 weeks
Monitor WBC & RBCs
what class is Colchicine
anti gout
Colchicine MOA
Reduces inflammatory response to the deposits or urate crystals in joint tissue
Colchicine indications
2nd line gout therapy
Colchicine SE
GI bleeding
Urinary bleeding
Colchicine nursing considerations
Powerful inhibitor of cell mitosis and can cause short term leukopenia
If have flu like sx / vomiting stop immediately because sign of toxicity
Contraindicated for any person with severe renal, gastrointestinal, hepatic disorders, cardiac disorders or bleeding disorders
what class is probenecid
Uricosuric agent
Uricosuric agent MOA
Inhibits reabsorption of uric acid in kidneys promoting excretion
probenecid indications
Treats hyperuricemia w/ gout
probenecid SE
GI upset
Dizziness or headache
Kidney/liver impairment
Lots of drug interactions
probenecid nursing considerations
Take w/ food and plenty of fluids
Lots of drug interactions
why is hormone therapy no longer used for osteoporosis
d/t risk of blood clots, breast cancer, & other canceres
osteomyelitis pharm
abx fro 4-6 weeks-> nafcillin, cefazolin, vancomycin
pharm for OA
manage pain & reduce swelling
mild to mod: acetaminophen, topical capsaicin, nsaids
mod to sev: rx nsaids, nsaids + colchinine, Tylenol + tramadol, opioids, steroid injections
how do NSAIDs work
by reducing production of prostaglandins which promote inflammation, pain and fever
what drugs are NSAIDs
aspirin
ibuprofen
naproxen
ketorolac
celecoxib
NSAIDs facts
-use lowest effective dose
-can affect kidney function
-risk for GI bleed
-contraindicated for pts w/ PUD
-use w/ caution if pmh of GI bleeds or on anticoags
goal of pharm for RA
-relieve pain and swelling
-slow or stop progression of disease
-long term drug therapy (NSAIDs, short term glucocorticoids, DMARDS)
what is the steroid of choice for RA + facts
-prednisone
-rapid suppression of inflammation
-only use when sx cannot be controlled by NSAIDs
