Final answer:
Antipsychotics or neuroleptics, such as chlorpromazine and haloperidol, are used to reduce psychotic symptoms. These drugs mainly treat schizophrenia and bipolar disorder by modulating dopamine activity in the brain.
Step-by-step explanation:
The type of drugs used to gradually reduce psychotic symptoms, including hyperactivity, mental confusion, hallucinations, and delusions, are known as antipsychotics or neuroleptics. These drugs, such as chlorpromazine and haloperidol, are primarily used in the treatment of psychiatric conditions like schizophrenia and bipolar disorder. They work by reducing the activity of dopamine in the brain, which can significantly alleviate symptoms like agitation, aggression, and delusions. Additionally, phenothiazines, including chlorpromazine, have other clinical uses due to their antiemetic, antinausea, and antihistaminic properties. It's also worth noting that other classes of psychoactive drugs are used to manage different mental disorders; for instance, antidepressants like sertraline for depression, anxiolytics such as buspirone and diazepam for anxiety disorders, and stimulants for attention deficit disorder.
