A client with laryngeal dystonia has gotten to the point that people on the telephone cannot understand her. She has heard about getting Botox injections into her vocal cords
The nurse will teach about the actions of Botox. Which is the most accurate description? This drug:
A) Will slow the decline in muscle strength and function
B) Produces paralysis of the larynx muscles by blocking acetylcholine release
C) Prevents the depolarizing effect of the neurotransmitters
D) Inhibits the peripheral metabolism of dopamine
Ans: B
Feedback:
Pharmacologic preparations of the botulinum toxin (botulinum type A toxin [Botox] and botulinum type B toxin [Myobloc]) produce paralysis by blocking acetylcholine release. Glucocorticoids are the only medication currently available to slow the decline in muscle strength and function in DMD. Curare acts on the postjunctional membrane of the motor endplate to prevent the depolarizing effect of the neurotransmitter. Neuromuscular transmission is blocked by curare-type drugs during many types of surgical procedures to facilitate relaxation of involved musculature. Levodopa, a dopamine agonist used in Parkinson disease, is administered with carbidopa, which inhibits its peripheral metabolism, allowing therapeutic concentrations of the drug to enter the brain without disabling adverse effects.
