Chlorpromazine is listed for which two uses?

• A. ADHD treatment
• B. Nausea and vomiting
• C. Both ADHD and Nausea
• D. Movement disorders

Answer: (C)

Chlorpromazine has both antiemetic and sedative/behavioral management properties, which is why it can be listed for two uses. Its antiemetic effect comes from dopamine D2 blockade in the chemoreceptor trigger zone, making it effective for nausea and vomiting, including postoperative and chemotherapy-induced cases. Historically, its sedating and calming effects have led to its use in managing agitation or disruptive behavior, which in some contexts has been described as ADHD-related symptoms, especially when hyperactivity or aggression is present. Modern ADHD treatment, of course, relies mainly on stimulants, but chlorpromazine has appeared in lists of indications due to its calming/behavioral effects in certain situations. Movement disorders are typically not an approved use; they are more commonly a potential side effect of antipsychotics rather than a primary indication.
