A child with a tic disorder is prescribed an antipsychotic agent as part of his treatment plan. Which of the following would the nurse expect to be prescribed?
A) Aripiprazole
B) Haloperidol
C) Clonidine
D) Guanfacine
Ans: A
Two classes of drugs are commonly used in the treatment of tics: antipsychotics and a-adrenergic receptor agonists. Aripiprazole is replacing the use of older antipsychotics, such as haloperidol and pimozide. These potent dopamine blockers are often effective at low doses. The a2-adrenergic receptor agonist clonidine has been used in treating Tourette's disorder for more than 30 years. Guanfacine is a newer a2-adrenergic receptor agonist that has only recently been studied in children with Tourette's disorder.
