Safe discontinuation of psychotropic drugs in older people? : New evidence and practical approach

Abstract

Many older patients are permanently prescribed one or more psychotropic drugs for treatment of symptoms, such as behavioral and psychological symptoms in dementia, depressive symptoms, anxiety, and insomnia. They therefore contribute to the risk of polypharmacy. Recently, deprescribing studies have been published in order to clarify if inadequate medications can be safely discontinued. This mini-review summarizes the study results and derives practical recommendations for routine use. A literature search was carried out in PubMed for clinical studies on deprescribing in association with psychotropic substances. After removal of duplications, 12heterogeneous clinical studies were identified and reduction of psychotropic substances could be successfully achieved in 8studies. In four of these studies psychological, behavioral and functional endpoints were reported. Criteria for successful deprescribing of sedatives were in particular motivation, information and sufficient cooperation of the patients and for antipsychotic drugs in people with dementia, the sustainable establishment of nonpharmaceutical treatment strategies. Deprescribing was not attempted in cases of ahistory of severe chronic mental illness and in cases of severe behavioral symptoms in dementia. Evidence for antidepressants was not sufficient to extract practical recommendations. Safe deprescribing of antipsychotic drugs in patients with dementia is justified if non-pharmacological treatment options are sustainably implemented, and for sedative drugs in well-informed, highly motivated and cooperative patients.
