The secondary objectives are:

To evaluate the clinical and biological safety of the association valproate-amisulpride to the association valproate-haloperidol;
To assess the patient status 3 weeks and 3 months after inclusion; and
To assess patient satisfaction at 3 months.

Using an effective contraception method (women of childbearing age only)

Exclusion criteria

Exclusion Criteria on D-3:

Having participated in a clinical trial within the three previous months

History of epilepsy
History of allergy or hypersensitivity to haloperidol or benzamides or valproate
Treated with fluoxetin within the past 4 weeks
Treated with injectable long-acting neuroleptics if, for the patient, the interval between 2 injection periods has not elapsed before pre-inclusion (D-3)
Treated with a mood stabiliser (other than valproate) at effective dose for less than 7 days preceding D-3 and for whom a modification is not justified
Bradycardia < 55 beats per minute (bpm)

Exclusion Criteria on D0:

Potentially significant alterations of laboratory tests on D0:
- ASAT or ALAT > 2 upper limit of normal (ULN). If ASAT or ALAT values range between 1.5 ULN and 2 ULN, the patient can be randomized and a new test will be performed 7 days after randomization;
- Alkaline phosphatase levels or bilirubin levels not within normal reference range.
QTc prolongation on D0; QTc Bazett > 450ms in male patients and QTc > 470ms in female patients on electrocardiogram (ECG).
