Background

Thioproperazine is a potent neuroleptic with antipsychotic properties. Thioproperazine has a marked cataleptic and antiapomorphine activity associated with relatively slight sedative, hypothermic and spasmolytic effects. It is virtually without antiserotonin and hypotensive action and has no antihistaminic property. It is used for the treatment of all types of acute and chronic schizophrenia, including those which did not respond to the usual neuroleptics; manic syndromes.

Pharmacodynamics

Thioproperazine is a potent neuroleptic with antipsychotic properties. Thioproperazine has a marked cataleptic and antiapomorphine activity associated with relatively slight sedative, hypothermic and spasmolytic effects. It is virtually without antiserotonin and hypotensive action and has no antihistaminic property.

Mechanism of action

Thioproperazine acts as an antagonist (blocking agent) on different postsysnaptic receptors -on dopaminergic-receptors (subtypes D1, D2, D3 and D4 - different antipsychotic properties on productive and unproductive symptoms), on serotonergic-receptors (5-HT1 and 5-HT2, with anxiolytic, antidepressive and antiaggressive properties as well as an attenuation of extrapypramidal side-effects, but also leading to weight gain, fall in blood pressure, sedation and ejaculation difficulties), on histaminergic-receptors (H1-receptors, sedation, antiemesis, vertigo, fall in blood pressure and weight gain), alpha1/alpha2-receptors (antisympathomimetic properties, lowering of blood pressure, reflex tachycardia, vertigo, sedation, hypersalivation and incontinence as well as sexual dysfunction, but may also attenuate pseudoparkinsonism - controversial) and finally on muscarinic (cholinergic) M1/M2-receptors (causing anticholinergic symptoms like dry mouth, blurred vision, obstipation, difficulty/inability to urinate, sinus tachycardia, ECG-changes and loss of memory, but the anticholinergic action may attenuate extrapyramidal side-effects).
