Frequently I have complained that the terms "typical and atypical" or "first generation and second generation" antipsychotics were not very helpful.  When I give chalk talks to junior residents and interns about antipsychotics, this is one of the first things that I note.  It is the medicines relative affinities for different receptors that appear to make the difference, not whether they were discovered prior to 1980 or not.  A few weeks ago, I was lucky enough to encounter a paper that was published in April of 2023 by McCutcheon et al in Biological Psychiatry titled "Data-Driven Taxonomy for Antipsychotic Medication: A New Classification System."  In this episode, I use their results to guide a discussion of variability in target effects and side effects of different groups of antipsychotics.Please leave feedback at https://www.psydactic.com or send any comments to feedback@psydactic.com.References and readings (when available) are posted at the end of each episode transcript, located at psydactic.buzzsprout.com.
