. D2/3 blockade (#amisulpride) and/or partial agonism (#aripiprazole) cause negative symptoms, motor dysfunction or impaired #striatal #reward activity in healthy volunteers. We found interesting differences between these commonly prescribed medications . 2/3.

We call for a ��thorough QT” (#TQT) study of aripiprazole, as has been undertaken for some other #antipsychotics. Until this is completed, we advocate closer ECG monitoring of patients on, or due to start, aripiprazole 🩺. @UCLPsychiatry @KingsIoPPN @MRC_LMS #psychopharmacology.
