Objective:
The authors assessed the effects on primary negative symptoms of low doses of amisulpride, a substituted benzamide neuroleptic with high affinity for D2 and D3 dopamine receptors.
Method:
Young, drug-free schizophrenic patients with pure negative symptoms participated in a 6-week double-blind trial of placebo (N = 10) or low-dose amisulpride (N = 10). They were assessed with the Scale for the Assessment of Negative Symptoms.
Results:
Amisulpride significantly improved negative symptoms. Improvement in avolition, attentional impairment, and retardation was significantly greater with amisulpride than with placebo.
Conclusions:
These findings suggest that some primary negative symptoms may be directly affected by low doses of benzamide neuroleptics.
