Der er dog i et forsøg med intramuskulære enkeltdoser af aripiprazol (dosis 15 mg) til raske frivillige, administreret samtidig med intramuskulært lorazepam (dosis 2 mg), set større grad af sedering ved kombinationen end for aripiprazol alene.
However, in a single-dose, intramuscular study of aripiprazole (dose 15 mg) in healthy subjects, administered simultaneously with intramuscular lorazepam (dose 2 mg), the intensity of sedation was greater with the combination as compared to that observed with aripiprazole alone.
