How Does Trifluoperazine Work?
Trifluoperazine belongs to a group of medications called phenothiazines. When used to treat schizophrenia, it is known as a typical (or first-generation) antipsychotic medication. It is not entirely known how the drug works.
However, it is known that trifluoperazine blocks or lessens the effects of dopamine, a chemical in the brain. Dopamine may be elevated in people with schizophrenia or anxiety. However, trifluoperazine is not a cure for schizophrenia or anxiety. It only helps to control symptoms (see Symptoms of Schizophrenia or Anxiety Symptoms).
