Jul 15, 2025
Introduction
An amisulpride tablet is a second-generation (atypical) antipsychotic medication used to treat various mental health conditions, particularly schizophrenia and acute psychotic episodes. It works by balancing dopamine activity in the brain, which helps control symptoms like hallucinations, delusions, and disorganized thinking.Amisulpride 400 mg tablet is typically prescribed for adults experiencing moderate to severe psychotic symptoms, and is sometimes also used in lower doses for depressive disorders or bipolar disorder under medical supervision.
Amisulpride Tablet Uses (amisulpride tablet uses)
Amisulpride tablets are clinically approved and widely used in the following conditions:
Primary Indications:
-
Schizophrenia – both positive symptoms (e.g., hallucinations, delusions) and negative symptoms (e.g., emotional withdrawal, flat affect)
-
Acute psychotic disorders
-
Bipolar mood disorders (off-label use in some regions)
-
Persistent delusional disorders
-
Depression with psychotic features (low-dose amisulpride)
How Amisulpride Tablet Works (amisulpride mechanism of action)
Amisulpride selectively blocks dopamine D2 and D3 receptors in specific areas of the brain. Unlike older antipsychotics, it does not significantly affect serotonin, nor does it interfere with other neurotransmitter systems like histamine or acetylcholine — which makes it more tolerable and less sedating.
Mechanism of Action Highlights:
-
Low doses (50–200 mg): Improve depressive symptoms by stimulating dopamine in certain brain regions.
-
High doses (400–800 mg): Block excess dopamine to treat psychosis and agitation.
This dose-dependent activity makes amisulpride tablets unique among antipsychotic medications.
