Question 2

A 59-year-old schizophrenic man has a history of dystonic reactions to typical antipsychotic medications. He now takes olanzapine as treatment of his schizophrenia. He is scheduled to undergo an inguinal hernia repair under general anesthesia. He has a history of postoperative nausea. Which of the following would be the most suitable anti-emetic medication for this man?

A) Droperidol
B) Aprepitant
C) Metoclopramide
D) Promethazine
E) Dronabinol

Aprepitant

Accepted Answer

Aprepitant is an expensive but effective anti-emetic agent that can be administered orally before surgery to decrease postoperative nausea and vomiting. Choices A, C, and D all have anti-dopaminergic effects and are contraindicated given his prior adverse reactions to typical antipsychotic medications. Dronabinol (a cannabinoid) could precipitate psychotic symptoms and would not be a good choice.
