Which drug is an example of a neuroleptic?

• A. Haloperidol
• B. Diazepam
• C. Lorazepam
• D. Midazolam

Answer: (A)

Neuroleptics are antipsychotic medications that primarily block dopamine D2 receptors in the brain, especially in pathways linked to psychosis. Haloperidol is a classic high-potency neuroleptic, acting as a strong D2 receptor antagonist to reduce psychotic symptoms like delusions and hallucinations. Because of this dopamine blockade, it can lead to extrapyramidal side effects such as muscle stiffness and tremors. The other drugs listed are benzodiazepines, which work by enhancing GABA activity to produce anxiolytic and sedative effects. They are not antipsychotics and do not fit the category of neuroleptics.
