01Why NbN

Moving beyond disease-based labels.

Psychotropic medications are frequently prescribed across clinical conditions far removed from the category they were originally named for. An “antidepressant” is prescribed for anxiety; an “antipsychotic” is prescribed for depression without psychosis.

NbN replaces those historic descriptors with contemporary knowledge about pharmacology and mechanisms of action — so the name of a medicine describes what it does rather than the population it was first studied in.

Traditional terminology
  • Based primarily on historic therapeutic categories.
  • Can be confusing when the same medicine is used across different indications.
  • Describes what a drug was once thought to treat, not what it does.
NbN approach
  • Pharmacologically driven from the ground up.
  • Built on mechanisms of action and contemporary neuroscience.
  • Designed to support informed, defensible clinical decisions.

Traditional terminology

One label, applied across unrelated clinical situations.

  • Antidepressant
  • Antipsychotic
  • Anxiolytic
  • Mood stabiliser

A category built for a different era of psychiatry. It tells you what a drug was once thought to treat — not what it does.

The NbN approach

One compound, described across five dimensions.

One compoundPharmacologyIndicationsEfficacyPracticalNeurobiology

Every compound in the app is described along the same five dimensions, so two medicines can be compared on mechanism rather than on marketing.

02Application showcase

Ten capabilities, one uninterrupted workflow.

Everything in the app is organised around how a prescribing decision is actually made — moving from a name to a mechanism to the evidence behind it.

01 / 10

NbN app search screen with the on-screen keyboard open, showing the “Search by Axis name” field above a magnifier illustration.

Fast medication search

Find a compound in seconds by generic or brand name, or search by disorder and symptom to work backwards from the clinical picture.

02 / 10

NbN app “Add Search Axis” screen with a name filter applied to the compound sertraline, and the on-screen keyboard open.

Keyword filtering

Stack filters across axes — a name, a pharmacology class, a mode of action — and narrow a long candidate list down to the compound you had in mind.

03 / 10

NbN app “Choose a search axis” sheet listing name, pharmacology, mode of action, approved indications, efficacy and side effects, and former terminology.

Pharmacology and mode of action

The primary dimension of the nomenclature: the neurotransmitter, molecule or system being modified, and the mechanism by which it is modified.

04 / 10

NbN app home screen: “Start smart prescribing” with the search field and the six search axes listed beneath it.

Approved indications

Regulatory indications drawn from the major authorities, kept visibly distinct from broader evidence of efficacy.

05 / 10

Efficacy and side effects

Where the clinical evidence is strong, and which adverse effects are prevalent or clinically serious enough to plan around.

03How it works

One primary dimension, four supporting ones.

Pharmacology and mode of action carry the nomenclature. Four additional dimensions supply the clinical and biological context around it.

01 / 05Primary dimension

Pharmacology and Mode of Action

The organising dimension of the nomenclature: the neurotransmitter, molecule or system being modified, and the mechanism by which the modification occurs.

  • Replaces historic therapeutic categories with contemporary pharmacological knowledge.
  • Pairs a pharmacology class with a specific mode of action for every compound.
  • Links directly to the corresponding IUPHAR pharmacology record.

04Built for clinical clarity

Scientific depth. Practical clarity.

NbN is not a simplified reference. It is a stricter one: every compound described by what it does, in language that holds up across specialities, settings and languages.

The wording throughout the app is deliberately precise. Nothing is framed as a guaranteed outcome, and nothing is presented as a substitute for clinical judgement.

  • 01

    Clinicians

    A pharmacological rationale for the next step in treatment, with approved indications, efficacy and practical notes in one place rather than scattered across references.

  • 02

    Researchers

    A consistent vocabulary for describing compounds by target and mechanism, with clinical and preclinical neurobiology kept visibly distinct.

  • 03

    Educators

    A teaching structure that presents the neuroscience fabric of psychotropics, and a way to explain why a historic category label can mislead.

  • 04

    Students

    An entry point that organises learning around pharmacology and mechanism from the start, rather than asking you to unlearn disease-based shorthand later.

  • 05

    Patients and families

    Clearer terminology for conversations about medication — a separate adaptation of the nomenclature is written specifically for patients and families.

05The initiative

Led by ECNP, in collaboration with four international colleges.

The Neuroscience-based Nomenclature is a joint initiative of five major neuropsychopharmacology organisations, assembled by a taskforce with a single mission: to embed contemporary neuroscience in the way psychotropic medications are named.

The taskforce includes representatives from each organisation, and the resulting nomenclature is recognised by international colleges and leading journals in the field.

Organisation marks are the property of their respective owners and are shown for identification only.

06Questions

Frequently asked questions.

Short, factual answers about the nomenclature and the app. For anything clinical, the initiative's own guidance remains the reference.

Still unsure about something? Contact the team or read the full guidance on the official site.

Neuroscience-based Nomenclature (NbN) is an international initiative that describes psychotropic medications by their pharmacology and mode of action rather than by historic disease-based categories. It was created to bring the language of psychopharmacology back in line with contemporary neuroscience, and it is developed and maintained by a taskforce drawn from five scientific organisations.

The app is built for anyone who needs to reason carefully about psychotropic medications: prescribing clinicians, researchers, educators and students, and the patients and families who want clearer terminology. A separate adaptation of the nomenclature exists for child and adolescent practice, and another is written for patients and families.

Every compound is presented across five dimensions: pharmacology and mode of action, approved indications, efficacy and side effects, a practical note, and neurobiology. The neurobiology dimension is divided into preclinical and clinical sections, and the pharmacology dimension links out to the relevant IUPHAR record for deeper target detail.

Yes. The app is free and available on both Google Play and the App Store. The nomenclature itself is also published on the initiative's website.

No. NbN is an educational and scientific resource. It is not a substitute for independent clinical judgment, diagnosis, or individualised medical advice, and it should not be used as the sole basis for a prescribing decision.

The nomenclature is a living document rather than a fixed standard. Applications are refreshed twice a year, in May and September, to reflect new reports and findings, and the app includes a feedback feature so that clinicians can submit observations and corrections for the taskforce to consider in later editions.
