olanzapine, quetiapine and risperidone. There are many patients who fail to respond to these drugs [9], leaving a window for the new entry [1]. Since a sizable number of patients do not adequately respond to the available drugs [1,[9][10][11][12], drugs such as ramelteon [9] and carbamazepine [11] Amisulpride is a second generation atypical antipsychotic that selectively binds to dopamine D 2 /D 3 receptors with 5-HT 7 antagonistic effect in the limbic system of the brain [14,15].

The current study explored the safety and tolerability of amisulpride in refractory patients with behavioral and psychological symptoms of dementia (BPSD), especially in agitation and/ or aggression.
