Clinical Pearl
Catatonia Induced by D2 Receptor Antagonist Antiemetics in a Patient With Multiple Sclerosis

This case report highlights the risk of catatonia precipitated by D2 receptor antagonist antiemetics (metoclopramide and domperidone) in patients with multiple sclerosis, emphasizing the need for caution when prescribing these agents to individuals with blood-brain barrier compromise.

Clinical Pearls

Bite-sized clinical takeaways from today's literature (sources from Feb 16 – Jun 06)

  • Consider early tapering from opioid agonist treatment only after 12-48 months to avoid significantly increased all-cause mortality risk associated with premature discontinuation.
  • Exercise extreme caution when prescribing D2 receptor antagonist antiemetics like metoclopramide to patients with conditions compromising the blood-brain barrier due to the precipitated risk of catatonia.
  • Utilize academic detailing outreach strategies in primary care settings to significantly increase prescribing rates of FDA-approved alcohol use disorder medications such as naltrexone and topiramate.
  • Reassess the long-term efficacy of antidepressants for relapse prevention beyond 12 months, as recent evidence suggests these benefits may be overstated.
  • In patients with comorbid bipolar disorder and alcohol use disorder, prioritize N-acetylcysteine over gabapentin to target dorsal anterior cingulate cortex glutamate levels and reduce heavy drinking days.
  • Monitor for antipsychotic-induced weight gain using pharmacogenomic testing profiles, as genetic factors play a significant role in predicting this adverse effect in severe mental illness.
  • Use intranasal midazolam (BXCL501) for rapid reduction of agitation in bipolar disorder and schizophrenia patients within home settings when immediate symptom control is required.
  • Consider clozapine as a viable off-label option for severe irritability in autism spectrum disorder, supported by real-world evidence comparing its profile favorably to standard adolescent schizophrenia treatments.
  • Be aware that regulatory hurdles may delay the availability of novel ADHD pharmacotherapies like CTx-1301, requiring reliance on current approved options while monitoring emerging trial data.
