Amisulpride is a substituted benzamide with high selectivity for dopaminergic D2 and D3 receptors. This study compared 800 mg/day amisulpride and 20 mg/day haloperidol in patients with acute exacerbations of schizophrenia. This multicenter, double-blind trial involved 191 patients allocated, after a 1 to 7-day wash-out period, to amisulpride (n = 95) or(More)
OBJECTIVE Four studies using identical protocols evaluated the safety and efficacy of four novel, evidence-based targets for antipsychotic agents: a neurokinin (NK(3)) antagonist (SR142801), a serotonin 2A/2C (5-HT(2A/2C)) antagonist (SR46349B), a central cannabinoid (CB(1)) antagonist (SR141716), and a neurotensin (NTS(1)) antagonist (SR48692).

This 4-week, double-blind, randomized study was undertaken to determine the dose-response relationship of amisulpride in 319 patients with acute exacerbation of schizophrenia. Fixed doses of amisulpride (400, 800 and 1200 mg/day) and haloperidol (16 mg/day) were compared to amisulpride, 100 mg/day, as a potentially subtherapeutic dose. Efficacy data (BPRS(More)
Amisulpride is an atypical antipsychotic with selective affinity for dopamine D2/3 receptors. In this long-term, open, randomised, multicentre trial, patients with chronic or subchronic schizophrenia received amisulpride (n =370) or haloperidol (n = 118) for 12 months. Dosage regimens were flexible (amisulpride 200-800 mg/day, haloperidol 5-20 mg/day).(More)
BACKGROUND Amisulpride is a substituted benzamide with high selectivity for dopamine D2 and D3 receptors. The purpose of the study was to evaluate the effect of 100 mg amisulpride in patients with predominantly negative symptoms of schizophrenia. METHOD This was a multi-centre, randomised, parallel-group, double-blind study. Patients received either(More)
The benzamide amisulpride (ASP) is a selective D2-like dopamine antagonist, while flupentixol (FPX), a thioxanthene, blocks D2-like, D1-like and 5-HT2 receptors. To evaluate efficacy and safety of ASP and to investigate the importance of an additional D1-like antagonism for antipsychotic effects and extrapyramidal tolerability, a randomized double-blind(More)
Amisulpride, a substituted benzamide with high selectivity for dopamine D3 and D2 receptors, was compared with the antipsychotic risperidone in patients with acute exacerbations of schizophrenia. The study was double-blind and involved 228 patients allocated, after a 3-6-day wash-out period, to amisulpride 800 mg (n = 115) or risperidone 8 mg (n = 113) for(More)
This multicenter, double-blind, randomized study evaluated the efficacy, safety and functional effects of two atypical antipsychotics, amisulpride and risperidone, in patients with chronic schizophrenia (DSM IV) with a recent worsening of symptoms. It was planned as a non-inferiority trial. 309 patients received amisulpride (400–1000 mg/day) or risperidone(More)
OBJECTIVE The goal of this placebo-controlled study was to evaluate the efficacy and safety of low doses of amisulpride, an atypical antipsychotic of the benzamide class with high affinity for D2 and D3 dopamine receptors, in the treatment of schizophrenic patients with predominantly primary negative symptoms. METHOD After completion of a 4-week washout(More)
Twenty-eight patients with acute schizophrenic illness received an oral daily dose of 200-800 mg perazine (Taxilan) for 4 weeks. Weekly plasma level determinations showed a constant perazine concentration from day 7 to day 28, whereas the equilibrium level of its metabolite desmethyl perazine was only achieved at day 14; on an average it amounted to twice(More)
