title: Quetiapine reduces irritability and risk of suicide in patients with agitated depression.
abstract: Patients who suffer from agitated depression accompanied by psychomotor agitation and irritability are prone to suicidal ideation and attempts and must therefore be diagnosed and treated with utmost care. Clinically, there have been more than a few cases of suicidal attempts that seemed to have been provoked by careless prescription of antidepressant medication. In the present study, administration of quetiapine to 3 patients in the acute phase of agitated depression resulted in rapid improvement in irritability and alleviation of depression. Depression in these 3 patients was caused by chronic (persistent) anxiety and tension. During the acute phase, the patients evidenced psychomotor agitation and irritability, often experiencing a sudden, overwhelming urge to commit suicide. Findings from the present study suggest that treatment with quetiapine in patients with this type of agitated depression can quickly alleviate symptoms of anxiety and irritability and reduce the risk of suicide.
