Public health psychopharmacology: a new research discipline comes of age?

Research evidence guiding the identification of pragmatic and effective actions aimed at improving the selection, availability, affordability and rational prescribing of medicines for mental disorders is sparse and inconsistent. In order to boost the development of new research, in this commentary we suggest to organise and classify all the activities in this area under a common theoretical framework and nomenclature, adopting the term 'public health psychopharmacology'. Public health psychopharmacology is proposed as a research discipline, based on contributions from the fields of regulatory science, health services research and implementation science. Implementing the term public health psychopharmacology may offer advantages, as the scientific community would be more focused on common goals and objectives, with, likely, an increasing body of research evidence of practical use.
