Policy & Regulation
Opinion: Trump’s executive order on psychedelics is the right move. But is my field ready for it?

President Trump's executive order accelerates psychedelic drug development and approval through FDA priority vouchers, DEA scheduling reforms, and ARPA-H funding, raising questions about clinical readiness.

Clinical Pearls

Bite-sized clinical takeaways from today's literature (sources from May 04 – May 06)

  • Consider prescribing Auvelity for agitation in Alzheimer's disease as a non-antipsychotic alternative to avoid extrapyramidal side effects and metabolic risks associated with typical antipsychotics.
  • Monitor brexpiprazole-treated inpatients closely for akathisia and insufficient efficacy, as these are the primary drivers of treatment discontinuation.
  • Maintain a high index of suspicion for pulmonary embolism in patients on clozapine even if D-dimer levels are falsely negative, as thromboembolic events can occur dose-independently.
  • Utilize lumateperone as a highly effective adjunctive option for major depressive disorder based on recent network meta-analysis rankings.
  • Address risperidone-induced hyperprolactinemia by considering the strategic addition of a second antipsychotic rather than immediate discontinuation of the offending agent.
  • Recognize that increased serotonergic activity reduces 'belief stickiness,' providing a mechanistic rationale for prioritizing serotonergic treatments in patients with rigid obsessions in OCD.
  • Be aware that emerging FDA rolling reviews for psilocybin therapy may soon alter the regulatory landscape and availability of psychedelic-assisted treatments for depression.
  • Evaluate the potential for novel psychedelic compounds like 25C-NBF in treatment-resistant depression, particularly given preclinical evidence of rapid antidepressant effects without classic addictive properties.
  • Consider the clinical implications of policy shifts aimed at reducing SSRI prescribing, ensuring that deprescribing decisions are evidence-based and do not compromise patient stability.
  • Monitor for signs of treatment resistance or adverse effects when initiating next-generation amisulpride formulations, noting ongoing phase 2 data supporting its efficacy in schizophrenia.
