Neuroscience-Based Nomenclature (NbN): the Portuguese version of the new classification for psychopharmacological drugs.

Neuroscience-Based Nomenclature (NbN) is a proposal to provide a nomenclature based on neuroscience and pharmacology instead of the old disease-based classification. NbN is based on the mechanism of action and pharmacological target and aims to assist in rational prescription, reduce stigma, and increase treatment adherence. Currently, NbN is endorsed by many psychiatric associations, adopted by several relevant journals, and included in major psychiatry textbooks. Therefore, it is important that NbN is known to psychiatrists.
