Prescribing Trends Psychotropic Drugs Against Children and Adolescents and Association with Polypharmacy Reduction Policy for Psychotropic Drugs: Based on Japanese National Database Survey.

In Japan, the polypharmacy reduction policy for psychotropic drugs is intended to reduce the reimbursement of medical costs when "three or more types of psychotropic drugs" are prescribed. However, non-polypharmacy patients who need multiple drugs are also comprehensively evaluated. This study demonstrated that the polypharmacy reduction policy for psychotropic drugs is associated with reductions of the amounts of in-hospital prescriptions for patients using antidepressants, antipsychotics, anxiolytics, and benzodiazepines.
