Question

Of the following antipsychotics, which is MOST LIKELY to cause extrapyramidal side effects?

1) Risperidone
2) Chlorpromazine
3) Clozapine
4) Haloperidol

Answer 1

Haloperidol is the antipsychotic drug most likely to cause extrapyramidal side effects, due to its potent dopamine antagonistic properties.

Step-by-step explanation:

Among the antipsychotic drugs listed, Haloperidol is most likely to cause extrapyramidal side effects. Antipsychotics are known to cause these side effects by affecting dopamine activity in the basal nuclei of the brain, which is crucial for controlling movement. Haloperidol, a traditional antipsychotic medication, is specifically known for its potent dopamine antagonistic properties leading to a higher propensity for such side effects compared to the other drugs listed like Risperidone, Chlorpromazine, and Clozapine.
