Thioridazine
Identification
- Summary
Thioridazine is a phenothiazine antipsychotic used to treat schizophrenia and generalized anxiety disorder.
- Generic Name
- Thioridazine
- DrugBank Accession Number
- DB00679
- Background
A phenothiazine antipsychotic used in the management of psychoses, including schizophrenia, and in the control of severely disturbed or agitated behavior. It has little antiemetic activity. Thioridazine has a higher incidence of antimuscarinic effects, but a lower incidence of extrapyramidal symptoms, than chlorpromazine. (From Martindale, The Extra Pharmacopoeia, 30th ed, p618).
Thioridazine was withdrawn worldwide in 2005 due to its association with cardiac arrythmias.

- Pharmacodynamics
Thioridazine is a trifluoro-methyl phenothiazine derivative intended for the management of schizophrenia and other psychotic disorders. Thioridazine has not been shown effective in the management of behaviorial complications in patients with mental retardation.
- Mechanism of action
Thioridazine blocks postsynaptic mesolimbic dopaminergic D1 and D2 receptors in the brain; blocks alpha-adrenergic effect, depresses the release of hypothalamic and hypophyseal hormones and is believed to depress the reticular activating system thus affecting basal metabolism, body temperature, wakefulness, vasomotor tone, and emesis.
