What are phenothiazine antipsychotics?
Phenothiazine antipsychotics are medications used to treat schizophrenia and manifestations of psychotic disorders. Some phenothiazine antipsychotics, like prochlorperazine and chlorpromazine, are used for nausea, vomiting, and hiccups.
Although, the exact mechanism of phenothiazine antipsychotics is unknown, scientists believe that they may work by blocking the action of dopamine in the brain. Dopamine is a neurotransmitter (chemical) that nerves use to communicate with one another. Phenothiazine antipsychotics are used when patients do not respond to other antipsychotics.
