Amisulpride--an open clinical study of a new benzamide in schizophrenic patients.
In pharmacological screening amisulpride produces no catalepsy, no inhibition of stereotypic movements, yet a blockade of drug-induced vomiting. During an open clinical trial lasting 4 weeks, 14 patients (13 schizophrenics) were treated with the compound. The (BPRS-) syndromes anxiety/depression, thought disorder, activity, hostility and the global score showed significant improvement. With the AMDP system significant changes were seen in the paranoid-hallucinatory, manic, depressive and hostility syndromes as well as in the global score. No changes were revealed in anergia (BPRS) and apathia (AMDP). In the EEG a significant decrease in the frequency of alpha-rhythms was found. The scores of the Simpson-scale for extrapyramidal side effects were low, but there was an acute dystonic reaction in one patient. In three cases akathisia occurred; biperiden administration was necessary three times. In conclusion, amisulpride showed good antipsychotic efficacy without sedation. Contrary to expectations based on the pharmacological screening, we did find extrapyramidal side effects.
