Clinical Predictors of Antidepressant Effects of Ketamine and Esketamine in Treatment-Resistant Unipolar and Bipolar Depression: A Systematic Review

This systematic review of 122 studies finds that most demographic and clinical variables do not reliably predict antidepressant response to ketamine or esketamine, with only early response and family history of substance use disorders showing promise for future investigation.

Clinical Pearls

Bite-sized clinical takeaways from today's literature (sources from Mar 25 – Jun 01)

  • When treating ADHD, avoid escalating doses beyond established optimal ranges as network meta-analyses show minimal additional clinical benefit.
  • Consider sex- and hormone-informed dosing strategies for antipsychotics, as hormonal status significantly influences pharmacokinetics and efficacy in women.
  • Reassure pregnant patients with depression that current evidence indicates no causal link between antidepressant use and neurodevelopmental disorders in offspring.
  • Monitor for new-onset depression in patients receiving sevoflurane anesthesia, as it is associated with a significantly higher long-term risk compared to propofol.
  • Initiate medications for alcohol use disorder promptly upon hospitalization, given that only 30% of AUD-related admissions currently receive evidence-based pharmacotherapy.
  • Be aware that chronic nitrous oxide use can cause protracted encephalopathy requiring vitamin B12, with limited long-term outcome data for psychiatric comorbidities.
  • Utilize early response to ketamine/esketamine and family history of substance use disorders as potential predictors for antidepressant response, as most other demographic variables are unreliable.
  • Recognize that a single 25 mg dose of psilocybin can produce rapid, clinically meaningful symptom reductions for depression within 48 hours.
  • Understand that the antidepressant effects of a single psilocybin dose can be sustained for over three months due to persistent changes in brain connectivity.
  • Apply formulation science principles when optimizing stimulant therapy for ADHD to better manage medication delivery and efficacy.
