two broad categories of drugs used to treat disorders of the musculoskeletal system
muscle relaxants
non-steroidal anti inflammatory drugs (NSAIDS)
medication used to treat some musculoskeletal disorders associated with pain, spasm, abnormal contraction or impaired mobility
muscle relaxant
true or false
muscle relaxants are given on a long term basis
false
they are given on a short term basis until the pain subsides
muscle relaxant drugs affect the _______ and ______ with no direct effect on skeletal muscle
spinal cord and brain
muscle relaxants produce a ______ effect promoting rest and relaxation
sedative
two drugs used to treat acute, painful musculoskeletal conditions include:
diazepam (valium)
methacarbomal (robaxin)
a different type of muscle relaxant that causes a direct effect on skeletal muscles and manages spasticity from upper motor neuron disorders
dantrolene
two upper motor neuron disorders
cerebral palsy
multiple sclerosis
this relaxant acts on the muscle itself and is not intended for use if caused by trauma
dantrolene
neuromuscular blocking agents are used for what?
surgical, endoscopic, or orthopedic procedures
succinylcholine and rocuronium (zemuron) are what types of muscle relaxants
NMBA's (neuromuscular blocking agents)
the major muscle of ventilation is the _____
diaphragm
NMBA's are potentially very dangerous and can result in respiratory arrest because of the potential to _________ the diaphragm
paralyze
who can administer NMBA's?
anesthesiologists or specially trained people
an antidote for NMBA's is:
neostigmine (prostigmine)
_______ can also be used to treat myasthenia gravis
prostigmin
skeletal muscle relaxant side effects
slurred speech
blurred vision
ataxia (defective muscular coordination)
weakness, drowsiness, dizziness, dry mouth
hypersensitivity
respiratory depression
the appropriate care for musculoskeletal injuries (acronym)
RICE
(rest, ice, compression, elevation)
______ drugs are used to treat disorders in which the musculoskeletal system is not functioning properly due to inflammation
anti-inflammatory
examples of conditions that require anti-inflammatory drugs
arthritis
bursitis
spondylitis
gout
muscle strains and sprains
can NSAIDS be given for lengthy time periods?
yes
the oldest drug in the NSAID category
Salicylates (aspirin)
anti inflammatory drugs that do not inhibit clotting and cause fewer gastric problems and less GI bleeding than other NSAIDS
COX-2 inhibitor
an example of an NSAID that inhibits COX-2 and has the potential to cause fewer gastric problems and pose less risk of GI bleeding
celebrex
these are side effects of ________
GI ulceration and bleeding
Epigastric pain
GERD
myocardial infarction
fluid retention
hematuria
rash
NSAIDS
these are contraindications with
asthma
kidney disease
liver dyfunction
children with viral infections
cardiovascular disorders
NSAIDS should be given with what to reduce GI side effects
meals or milk
a metabolic disorder characterized by accumulation of uric acid crystals in various joints, especially the big toe, ankle, knee, and elbow with resultant pain and swelling
gout
side of effects of gout meds
blood disorders
rash
GI upset
diarrhea
what should be encouraged to facilitate excretion of uric acid crystals?
large fluid intake
______ is a specific drug that is used to relieve inflammation in acute gouty arthiritis
colchicine
a disease characterized by low bone mass and deterioration of bone tissue, leading to bone fragility and increased susceptibility to fracture, especially to the hip, spine, and wrist
osteoporosis
osteoporosis effects the older population but primarily who?
postmenopausal women
osteoporosis therapy include:
calcium and vitamin D supplementation and several prescription meds
bone loss occurs with the first ___ years after the onset of menopause
5
nonhormonal agents that act directly to inhibit bone reabsorption, thereby increasing bone mineral density at the spine and hip as well as decreasing the incidence of first and future fractures
bisphosphonates
first line therapy bisphosphonates approved for prevention and treatment of osteoporosis (3)
alendronate (fosamax)
ibandronate (boniva)
risedronate (actonel)
a chronic disorder characterized by fractures, skeletal abnormalities, and significant bone pain
paget's disease
bisphosphonate side effects
GI distress (nausea, dyspepsia, esophagitis)
abdominal and chest pain
these are contraindications for ______
hypocalcemia
renal failure
inability to sit upright for 30-60 mins
bisphosphonates
should bisphosphonates be taken after the first meal?
