Phenothiazines or phenothiazines are a class of drugs used to treat mental disorders, such as schizophrenia and psychotic disorders. Some of this class of drugs can also be used to treat other conditions, such as nausea and vomiting and hiccups

Phenothiazine is a typical or first-generation antipsychotic drug. Drugs in this class generally work by blocking dopamine receptors in the brain. By doing so, this drug can reduce the effects of excessive dopamine work, such as psychotic symptoms such as hallucinations and delusions, or anxiety.

Although the exact mode of action is not known, this drug can also be used to treat some non-psychotic symptoms, such as severe nausea, vomiting, or hiccups. In fact, one of the phenothiazine drugs called promethazine is not used as an antipsychotic at all.
