Which medication will be prescribed for a patient complaining of muscle spasms resulting from a back injury?
a. Acetaminophen (Tylenol)
b. Morphine sulfate
c. Bethanechol (Urecholine)
d. Cyclobenzaprine (Flexeril)
ANS: D
Cyclobenzaprine is a centrally acting skeletal muscle relaxant, which is a group of drugs used to relieve acute muscle spasms. Their exact mechanism of action is unknown, except that they depress central nervous system (CNS) function. All the centrally acting skeletal muscle relaxants produce some degree of relaxation, and health care providers maintain that the benefits from the sedative effects may exceed the benefits from actual muscle relaxation. Acetaminophen, morphine, and bethanechol do not relieve skeletal muscle spasms.
