Antipsychotics, benzamides (ATC code: N05AL05)

The preparation is indicated for treatment of acute and chronic schizophrenia. It is efficient in treatment of positive symptoms with delusions, hallucinations and thought disorders. It primarily treats negative symptoms with blunted affect, emotional and social withdrawal which accompany schizophrenia.

Pharmacological properties

Amisulpride is an atypical antipsychotic agent with a benzamide structure, an analogue of sulpiride. It acts as a potent antagonist at D₂ and D₃ receptors. Its mechanism of action is biphasic — at low doses it blocks presynaptic dopamine receptors (which induces dopamine release responsible for disinhibitory effect) and at higher doses it blocks postsynaptic receptors. It does not act on serotonin, adrenergic, histamine or muscarinic receptors. It has a mild sedative and hypotensive effect, mild extrapyramidal symptoms and it has no anticholinergic effect.

Pharmaceutical form

Tablets, film-coated tablets

Special warnings and precautions for use

Amisulpride may cause neuroleptic malignant syndrome, increase the risk of cerebrovascular accident, prolong the QT interval and worsen Parkinson’s disease. Amisulrpide may increase the effect of alcohol on the CNS and therefore alcohol must not be consumed during treatment. It is advised not to use the product during pregnancy. In newborns who were exposed to amisulpride use in the 3^rd trimester there is a risk of development of extrapyramidal or withdrawal symptoms. Decreased fertility in women was observed.
