1. ???? Basic Product Identification
Generic Name: Amisulpride
Drug Class: Atypical antipsychotic (benzamide derivative)
Therapeutic Category: Schizophrenia & depressive disorders (low Global amisulpride API Manufacturer in Brussels dose)
Dosage Forms: Tablets (50 mg, 100 mg, 200 mg, 400 mg typical)
Prescription Type: Psychiatric specialist drug
Key Feature: Dose-dependent dual action (low vs high dose effects)
2. ???? Therapeutic Knowledge
Indications:
Schizophrenia (positive symptoms)
Acute psychosis
Low-dose: dysthymia / depressive symptoms (some markets)
Clinical role:
First-line or second-line antipsychotic (region dependent)
Onset: Days to weeks
⚠️ Key feature:
Dose-dependent pharmacology (very important clinically)
3. ⚙️ Mechanism of Action (MOA)
Selective D2/D3 dopamine receptor antagonist
Limbic system selective action → fewer extrapyramidal effects vs typical antipsychotics
D2/D3 blockade→↓Dopamine hyperactivity→↓Positive symptoms of schizophrenia
???? Dose-dependent effect:
Low dose: presynaptic D2 blockade → ↑ dopamine release → antidepressant effect
High dose: postsynaptic D2 blockade → antipsychotic effect
4. ???? Pharmacokinetics (ADME)
Absorption
Oral bioavailability: ~48–50%
Distribution
Moderate protein binding (~17%)
Crosses blood-brain barrier
Metabolism
Minimal hepatic metabolism
Low CYP interaction risk
Excretion
Renal excretion (mostly unchanged)
Half-life
~12 hours (longer in renal impairment)
5. ???? Dosage & Administration
Schizophrenia
400–800 mg/day (divided doses)
Max: ~1200 mg/day
