Antipsychotics are used to treat symptoms related to psychosis and Schizophrenia.

Traditional/Conventional Antipsychotics

Also known as Neuroleptics, these block Dopamine receptors, and are used to treat positive symptoms of Schizophrenia. Examples include Thorazine (Chlorpromazine), Mellaril (Thioridazine), and Haldol (Haloperidol). Side effects include Anticholinergic effects, Extrapyramidal effects, and Neuroleptic Malignant Syndrome.

Atypical/Novel Antipsychotics

These act on receptors for Serotonin, Norepinephrine, and Dopamine. Examples include Clozaril (Clozapine) and Risperdal (Risperidone). They are less likely to produce tardive dyskinesia. Side effects include Anticholinergic effects, Neuroleptic Malignant Syndrome, sedation, lowered seizure threshold, and agranulocytosis (Clozaril).

Anticholinergic effects: dry mouth, blurred vision, tachycardia, and constipation.
Extrapyramidal effects: akathisia, Parkinsonism, and tardive dyskinesia.
Neuroleptic Malignant Syndrome: muscle rigidity, tachycardia, hyperthermia, and altered consciousness.
