Antipsychotic effects and tolerability of the sigma ligand EMD 57445 (panamesine) and its metabolites in acute schizophrenia: an open clinical trial

Psychiatry Res. 1999 Dec 27;89(3):275-80. doi: 10.1016/s0165-1781(99)00100-6.

Abstract

Antipsychotic efficacy and side effects of the selective sigma ligand EMD 57445 (panamesine) were investigated in 12 patients (6 males, 6 females) who met DSM-III-R criteria for schizophrenia. A 4-week open clinical study revealed only modest effects of EMD 57445 and its metabolites on positive and negative symptoms of schizophrenia. Extrapyramidal and other side effects were moderate, although a significant increase in mild dyskinetic movements was found. Five patients, four of whom were females, completed the trial. Dropouts were mainly due to treatment failure. Antipsychotic effects were significantly greater in female than male patients.
