It has become clear that the current pharmacological nomenclature of psychotropic medications does not reflect our contemporary knowledge, nor does it inform properly the clinician of neuroscience-based prescriptions. Very often we prescribe “antidepressants” for “anxiety” disorders or “second-generation antipsychotics” to depressed patients. This practice is confusing. • Five international organizations ECNP, ACNP, AsCNP, CINP & IUPHAR decided five years ago to establish a taskforce and gave it the mission to embed our current neuroscience advances in the nomenclature. • The scope is to include all the medications with CNS indications and to harness this new nomenclature to help clinicians when they are trying to figure out what would be the next rational “neuropsychopharmacological step”. • In this second edition 22 new medications were added so NbN includes now 130 medications. This proposed nomenclature aims to reflect the current pharmacological knowledge base and cannot necessarily represent the ultimate scientific truth. The taskforce that assembled could have taken the stand that our current knowledge base is not enough to define the primary target or the correct mechanisms of action. But as a taskforce, we feel that it’s better to present a cutting-edge scientific interpretation than to wait for the definitive conclusion. We need to treat our patients now, and we cannot postpone treatment until all the facts are known. Therefore this nomenclature is based on: 1. The need to treat now. 2. Updated neuroscience insights. 3. The judgment of the members of the taskforce. Along these lines, we have come up with the following proposal: The Nomenclature: Pharmacology and Mode of Action – reflects the current knowledge and understanding about the targeted neurotransmitter/ molecule/system being modified and the mode/mechanism of action. We also added 4 additional dimensions 4 Additional Dimensions: Approved Indications – based on the recommendations of major regulatory bodies (e.g. FDA, EMA, etc.) Efficacy and Side Effects – Driven from positive single, large, RCT and/or “heavy solid weight” clinical data. Only prevalent or life-threatening side effects were included Practical Note – Summarizes the clinical knowledge that has been "filtered" through the taskforce's "sieve" Neurobiology – This dimension is focused on the biology. It is divided into preclinical and clinical sections, with the emphasis on the latter For those who would like to know more abo derived from empirical data.ut the pharmacology, there is a direct link to the relevant site of IUPHAR – our collaborator in this endeavour. As this is on-going process, we recognize that the product is imperfect. Based on your feedback (and taking into account the feedback of other colleges) new reports and findings, appropriate updates (e.g. later editions) will be undertaken.

Verdict
The clearest difference is in-app purchases: NbN3 at none against Lanthier's 2. NbN3 also leads on rating (4.1 vs 3.8) and iOS requirement (12.0 vs 16.0). Lanthier's advantage is review sentiment (62% vs 39%). On price, ratings volume, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Lanthier sells 2 in-app purchases, starting at $19.49 per year. NbN3 asks for nothing beyond the download.
NbN3 holds the better App Store score, 4.1 against 3.8. Both are backed by a comparable volume of ratings — 5 and 7 respectively. Written reviews complicate that: 62% of Lanthier's written reviews are positive against 39% of NbN3's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. Both last shipped on September 10, 2026.
