DRUG CLASS AND MECHANISM: Fluphenazine is an oral antipsychotic medication used for the management of schizophrenia. Fluphenazine is one of the older, first-generation piperazine phenothiazine antipsychotic medications. Examples of other phenothiazines include:

  • prochlorperazine (Compazine, Compro, Procomp),
  • chlorpromazine (Promapar, Thorazine),
  • perphenazine, trifluoperazine (Stelazine), and
  • thioridazine (Mellaril).

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.

The FDA approved fluphenazine in September 1959.
