Cisapride worsened psychotic symptoms in a schizophrenic patient taking bromperidol. Drug levels of bromperidol increased after cisapride addition, indicating a potential drug interaction.

Area of Science:

  • Pharmacology
  • Psychiatry
  • Clinical Toxicology

Background:

  • Schizophrenia is a chronic mental disorder often treated with antipsychotic medications.
  • Bromperidol is a typical antipsychotic used for managing psychotic symptoms.
  • Cisapride is a gastroprokinetic agent.

Observation:

  • A patient with schizophrenia experienced a significant worsening of psychotic symptoms while on bromperidol therapy.
  • The symptom exacerbation coincided with the addition of cisapride to the patient's medication regimen.
  • Plasma drug concentrations were analyzed retrospectively.

Findings:

  • Retrospective analysis revealed elevated plasma concentrations of bromperidol and its reduced metabolite following cisapride administration.
  • This suggests that cisapride may inhibit the metabolism or clearance of bromperidol.

  • The observed increase in bromperidol levels correlates with the clinical deterioration.

    • Implications:

    • This case highlights a potential pharmacokinetic interaction between cisapride and bromperidol.
    • Clinicians should be aware of this possible interaction when co-prescribing these agents.
    • Further research is warranted to elucidate the mechanism and clinical significance of this drug interaction.
