Drug intelligence / Profile preview
This entry refers to a group of first-generation and second-generation antipsychotic medications utilized in the DREAMS-Phen clinical trial (NCT04718311) sponsored by the University Hospital of Strasbourg. The study evaluates two treatment strategies—dose reduction versus maintenance treatment—in patients stabilized from schizophrenia spectrum disorders, stratified by their psychotic phenotype (cycloid vs. non-cycloid). The medications included in this group represent a mix of atypical antipsychotics (olanzapine, risperidone, quetiapine) and typical antipsychotics (zuclopenthixol, pipotiazine, flupentixol), which primarily function through the antagonism of dopamine D2 and serotonin 5-HT2A receptors to manage positive and negative symptoms of psychosis.
