Twenty-six chronic schizophrenic outpatients receiving low-potency anticholinergic neuroleptics were switched over periods of up to 2 years to an equivalent dose of high-potency neuroleptics. Of these patients, 85% experienced withdrawal symptoms, mainly insomnia, anxiety, and tensional restlessness. Complete withdrawal of low-potency medication was achieved during the study period in 9 patients only. The mean duration of treatment with low-potency neuroleptics was 15 years and the mean dose was 147 mg chlorpromazine equivalents/day. It is suggested that new symptoms associated with withdrawal of low-potency neuroleptics may lead to overcompliance by patients and difficulty in achieving the minimum therapeutic dosage. Thus, low-potency neuroleptics would not appear suitable for the long-term treatment of most schizophrenic patients.

Acute laryngeal dystonia (ALD) is a rare but potentially life-threatening complication of both first-generation (FGA) and second-generation (SGA) antipsychotic medication. Delays in diagnosis and treatment have been associated with mortality. We carried out a systematic review of antipsychotic-induced acute laryngeal dystonia using the databases Ovid MEDLINE, PubMed, CINAHL, and EMBASE.

SEP-383856 (SEP-856) is a novel antipsychotic under clinical development. It displays a unique pattern of receptor interaction, with only weak (partial agonist) activity at dopamine D receptors, yet more potent agonist activity at the trace amine associated receptor (TAAR1) and 5-hydroxytryptamine 1 A receptor (5-HT). Nonetheless, these observations await independent confirmation and more detailed characterization of the in vitro and in vivo actions of SEP-856 at TAAR1 and 5-HT receptors would be instructive.

The 5-hydroxytryptamine 7 (5-HT 7 ) receptor is reported to have considerable constitutive activity when transfected into cells. Constitutive activity-receptor activity in the absence of known agonist-is important for understanding the contributions of a receptor to (patho)physiology. We test the hypothesis that the 5-HT 7 receptor possesses constitutive activity in a physiological situation.

Objectives: The prevalence of akathisia is variably reported in the literature and its psychiatric impact is little studied. The aim of this study was to establish the prevalence, the associated factors, and the psychiatric impact of akathisia among patients undergoing antipsychotic treatment.
Methods: A cross-sectional descriptive study was carried out at the Department of Psychiatry A, at Razi Hospital, in Tunis.
