Olanzapine-Samidorphan for Schizophrenia: New Real-World Adherence Data - Psychiatric Times

New real-world adherence data for the olanzapine-samidorphan combination provides clinical insight into patient persistence with this antipsychotic regimen for schizophrenia.

Clinical Pearls

Bite-sized clinical takeaways from today's literature (sources from May 16 – May 20)

  • Consider a sequential regimen of ketamine followed by low-dose buprenorphine to extend the duration of anti-suicidal effects from one week to over a month in adults with major depressive disorder.
  • Use clozapine as a first-line consideration for patients with comorbid schizophrenia and conduct disorder, given its superior efficacy for aggressive behavioral symptoms.
  • Monitor hepatic function closely when prescribing psychotropic medications, as antidepressant-induced liver injury remains a significant clinical risk requiring vigilant management.
  • Reassure patients and families regarding ADHD medication safety by citing real-world data showing no increased cardiac risk associated with stimulant and non-stimulant treatments.
  • Prioritize SSRIs or NDRIs for post-stroke depression, utilizing specific clinical guidance on antidepressant selection tailored to this patient population.
  • Exercise caution with off-label leucovorin for autism spectrum disorder, as its rapid surge in prescribing lacks established clinical efficacy and is driven largely by media influence.
  • Evaluate ECT as a viable treatment option for refractory psychosis in patients with Huntington disease-like 2 when standard pharmacotherapy fails.
  • Review new real-world adherence data for the olanzapine-samidorphan combination to better anticipate and address patient persistence challenges in schizophrenia management.
  • Be aware of the rare but serious adverse event of sudden loss of consciousness associated with psilocybin ingestion when considering psychedelic therapies.
  • Consider mirtazapine as a potential repurposing opportunity for the treatment of methamphetamine use disorder based on emerging investigative data.
