[Exam 1] Module 3: The Musculoskeletal System Flashcards
What is Rheumatoid Arthritis?
An inflammatory, systemic autoimmune disease of the joints and surrounding structures. Primarily affects synovial joints but can occur in any area with connective tissue
RA can result in
joint stiffness, pain, swelling, and deformity.
Goal of drug therapy for RA?
Decrease joint pain and inflammation and prevent disabling deformities
What is Osteoporosis?
Progressive disease that results in reduced bone mass, decrease bone density, and increased risk for fractures
Three main types of drugs to treat RA?
NSAIDS
Glucocorticoids
Disease-modifying antirheumatic drugs (DMARDS)
What are DMARDS?
Immunosuppressive drugs that decrease joint inflammation and joint dmage. Delay progression of RA
You initially give DMARDS with NSAIDS because
onset of DMARDS therapeutic effect may take weeks
Categories of DMARDs?
Nonbiologic (traditional) and biologic DMARDS
What are the four main drugs to prevent or treat osteoporosis?
Selective Estrogen REceptor Modulators (SERMs)
Biphosphonates
Calcitonin
Calcium Supplements
SERMs: Primary therapeutic use is
the prevention and treatment of postmenopausal osteoporosis.
Also for women at risk for estrogen-dependent or receptor positive cancer and had treatment for estrogen-dependent or receptor positive cancer
SERMs: Prototype Drugs?
Raloxifene (Evista) which is a Bone Resportion Inhibitor.
Tamoxifen (Nolvadex) was the first serm, but other used because it poses less risk of uterine cancer
SERMs: Expected Pharmacologic Action
Activate estrogen receptors in some tissues and block receptors in other tissues.
Decreases bone resorption and bone loss, maintaining bone mideral density.
SERMs and Expected Pharmacologic Action: Raloxifene blocks
access o estrogen receptors in breast tissue, making it valueable for clients with estrogen-dependent or positive cancer.
Raloxifene does not activate receptors in endometrium, while other SERMs do
SERMs: ADR of SERM drugs relate primarily to
activation of estrogen receptors
SERMs: Serious adverse effects of Raloxifene are
increased risk of stroke, pulmonary embolism, and deep vein thrombosis
SERMs: Clients may have what due to blockage of estrogen receptors in other tissue
Hot flashes
SERMs: Women pregnant or breastfeeding should not take this because
They are teratogenic and can damage a developing fetus.
SERMs: Interventions include monitoring
BMD
Observe for development of thrombo-emboli in either the lower legs or lungs such as leg cramps and difficulty breathing
SERMs: Interventions, Raloxifene can cause fluctuations in certain components of blood such as
cholesterol, hormones, and fibrinogen.
SERMs: Admisteration includes
taking orally and on a daily basis. Clients cna take them with or without food
SERMs: Client Instructions include
Consume Adequate amount of Calcium and Vitamin D
Perform daily weight bearing exercises
Avoid getting pregnant
If premenopausal and using raloxifene to prevent breast cancer, warn of hot flashes
SERMs: Client Instructions: Patients must report pain in the lower extremities, particualrly in calves or chest pain with difficulty breathing because it may indicate
a blood clot has formed in the leg and or traveled to the lungs
SERMs: Contraindications include
Having Raloxifene and Tamoxifen not be taken in pregnant women .
Client who develops DVT cannot take the drug .
Make sure those with elevated serum lipids use SERMS with caution
SERMs: Interactions: Because of increased risk for estrogen-supported cancers, concurrent admiistration of what is not recommended?
Estrogen.
Biphosphonates: Therapeutic use is for
prevention and treatment of postmenopausal osteoporosis in women, age-related osteoporisis in men, and glucocortioid related osteoporissi in clients who were on that long-term therapy
Biphosphonates: Prototype and Other Drugs
Prototype is Alendronsate (Fosamax) with Bone REsorption Inhibitor Class
Risedronate (Actonel)
Ibandronate (Boniva)
Biphosphonates: Expected Pharmacologic Action is
Drecrease bone resorption by inhibiting activity of osteoclasts
Biphosphonates: Adverse drug reactions include
GI Disturbances like Esophagitis, N/V, and Abdominal Pain
Muscle and Joint Pain may occur, managed by mild analgesic
Eye Pain and Vision Changes may occur
Biphosphonates: Client Instructions
Take with full glass of water, then sit or stand for 30 minutes , avoiding eating or drinking anything other than water for 30 minutes
Avoid taking calcium supplement or antaciad
Take mild analgesic for muscle or joint pain
Tell provider about difficulty swallowing or changes in vision
Biphosphonates: Contraindications include
Those with Esophageal Strictures or difficulty swallowing
Dont give to those who are unable to stand/sit for 30 minutes or those with hypocalcemia or renal insufficiency
Biphosphonates: Contraindications. give cautions to those who have other
upper GI disorders, active infection, liver disease, or heart failure
Biphosphonates: Interactions
Calcium supplement and dairy products decrease absorption of biphosphates so do not give them within 30 minutes of administration
Calcitonin: Unlike SERMs, biphosphonates and calcium supplements, this cannot prevent
osteoporisis
Calcitonin: Therapeutic uses are for
treating established postmenopausal osteoporsis, as well as hypercalcemia secondary to hyperparathyroidism and Pagets disease
Calcitonin: Prototype and Other Drugs
Calcitonin-Salmon (Miacalcin, Calcimar) which is a Hypocalcemic
Calcitonin: Expected Pharmacologic Action
Decrease Bone Resorption by inhibiting action of osteoclasts and increasing excretion of Calcium
Also valueable in decreasing serum calcium in clients who are experiecing hypercalcemia
Calcitonin: Adverse Drug Reactions: Anaphylaxis can occur in clients with allergy to
Salmon protein or gelatin diluent
Calcitonin: Adverse Drug Reactions: Becauses calcitonin increased real excretion of calcium…
hypocalcemia can occur if excretion exceeds intake.
Calcitonin: Adverse Drug Reactions: Clients taking nasal form may experience
nasal dryness and irritation with therapy along with headaches
Calcitonin: Adverse Drug Reactions: Clients taking injectable form may experience
injection site reactions, N/V, Polyuria.
Calcitonin: Adverse Drug Reactions: Experience decrease in therapeutic effect if
they take calcitonin over long period of time
Calcitonin: Interventions: What happens here?
If taken Intranasally, assess the nostrils prior to administration.
Monitor for Hypocalcemia like muscle spasms or tingling of fingers or toes.
Calcitonin: Interventions: When treating with calcitonin-salmon, provide diet high in
calcium and vitamin d to prevent hypocalcemia from occurin g
Calcitonin: Interventions Safety Alert
Anaphylatic shock can occur in clients allergic to salmon or other fish
Perform allergy test prior to therapy
Calcitonin: Administration: Instructions
Intranasal: Hold nasal pump in upright manner. Spray in one nostril and alternate on daily basis.
Subcutaneous: Rotate injection sites
Calcitonin: Administration: Precautions for Parenteral Calcitonin?
Keep from light and keep it in a refrigerator
Calcitonin:Client Instructions:
Intranasally: Prime the pump for each new container prior to first use. Alternate nostril daily.
Notify immediately if rash or itching occurs.
Encourage consumption of diet high in calcium and vitamin D.
May lose effectiveness after a year or more
Calcitonin: Contraiindications and Precautions:
COntraindications include clients who are allergic to salmon or other fish protein
Calcitonin: Interactions
Those taking lithium may experience decrease in serum lithium levels.
Previous treatment with biphosphonates may decrease bodys response to calcitonin.
Calcium Supplements: Therapeutic uses include
Hypocalcemia and clients who either have a calcium deficiency or at risk of experiencing a calcium deficiency
Calcium Supplments: What is the primary component of several antacids that treat gastric hyperacidity?
Calcium Carbonate
Calcium Supplments: Prototype and OTher Drugs: Drug Classification
Mineral and Electrolyte Supplements
Calcium Supplments: Prototype and OTher Drugs: Two Prototypes are
Calcium Citrate (Citacal), which is used for calcium replacement as dietary supplements
Calcium Carbonate (Tums) but is primary on the market as an antacid
Calcium Supplements: Expected Pharmacologic Action: They are expected to provide
Non-dietary source of Calcium. Calcium effective in neutralizing gastric acid.
Often use with Vitamin D because it enhances absorption of calcium from intestine
Calcium Supplements: Adverse Drug Reactions: Clients who take calcium supplement or antacid on llong term basis or take vitamin D along with it are at risk for
Hypercalcemia
