Trifluoperazine (Eskazinyl, Eskazine, Jatroneural, Modalina, Stelazine, Terfluzine, Trifluoperaz, Triftazin) is a typical antipsychotic of the phenothiazine chemical class.

The primary application of trifluoperazine is for schizophrenia. Other official indications may vary country by country, but generally it is also indicated for use in agitation and patients with behavioural problems, severe nausea and vomiting as well as severe anxiety. Its use in many parts of the world has declined because of highly frequent and severe early and late tardive dyskinesia, a type of extrapyramidal symptom. The annual development rate of tardive dyskinesia may be as high as 4%.[citation needed]

A 2006 study suggested that trifluoperazine may be able to reverse addiction to opioids.[1]

A multi-year UK study by the Alzheimer's Research Trust suggested that this and other antipsychotic drugs commonly given to Alzheimer's patients with mild behavioural problems often make their condition worse.[2] The study concluded that

For most patients with AD, withdrawal of neuroleptics had no overall detrimental effect on functional and cognitive status and by some measures improved functional and cognitive status. Neuroleptics may have some value in the maintenance treatment of more severe neuropsychiatric symptoms, but this possibility must be weighed against the unwanted effects of therapy. The current study helps to inform a clinical management strategy for current practice, but the considerable risks of maintenance therapy highlight the urgency of further work to find, develop, and implement safer and more effective treatment approaches for neuropsychiatric symptoms in people with AD.


Trifluoperazine has central antiadrenergic,[3] antidopaminergic,[4][5] and minimal anticholinergic effects.[6] It is believed to work by blockading dopamine D1 and D2 receptors in the mesocortical and mesolimbic pathways, relieving or minimizing such symptoms of schizophrenia as hallucinations, delusions, and disorganized thought and speech.[7]
