Clinical Pearls

Bite-sized clinical takeaways from today's literature (sources from May 17 – Jun 02)

  • Discontinue zonisamide immediately if homicidal ideation emerges, as this severe psychiatric adverse effect has been documented in case reports.
  • Consider brexpiprazole, aripiprazole, or olanzapine as first-line antipsychotic options for schizophrenia based on the 2025 Japanese Expert Consensus for symptom-specific management.
  • Monitor pediatric patients on dopamine D2 receptor modulators closely for high non-persistence rates and increased healthcare utilization due to adverse events.
  • Utilize new pharmacogenomic testing to explain non-response to ADHD medications and optimize stimulant prescribing strategies.
  • Recognize that SSRIs have limited efficacy for PTSD and consider emerging treatments such as MDMA, psilocybin, or virtual reality exposure therapy for treatment-resistant cases.
  • Be aware that flumazenil trials are investigating the reversal of benzodiazepine effects during electroconvulsive therapy to potentially improve cognitive outcomes.
  • Note that GLP-1 receptor agonists are increasingly prescribed off-label for metabolic comorbidities in mood disorders, with prescribing rates increasing five-fold from 2018 to 2023.
  • Consider repurposing existing non-psychiatric drugs such as ACE inhibitors and metformin for major depression based on novel drug targets identified through Mendelian randomization.
  • Understand that current ADHD clinical trial methodologies may fail to capture critical dosing failure modes, limiting the evidence base for optimal pharmacotherapy.
  • Acknowledge that while psilocybin shows potential for increasing abstinence in cocaine use disorder, its regulatory status remains restricted to approved clinical trials in jurisdictions like Australia.
