Question

Quizplus · Accepted Answer

Phencyclidine (PCP) is a dissociative drug that blocks the NMDA receptor and produces both positive (psychotic symptoms such as delusions and hallucinations) and negative (amotivation, flat affect) symptoms of schizophrenia. It is also known to cause cognitive impairment and affective changes. The other options, dopamine antagonists (A), haloperidol (B), chlordiazepoxide (D), and amphetamine (E) may be used to treat schizophrenia or produce symptoms similar to those seen in schizophrenia, but do not produce both positive and negative symptoms.
