Clinical Outcomes in Patients Taking Inhaled Loxapine, Haloperidol, or Ziprasidone in the Emergency Department.

OBJECTIVES: Our objective was to compare outcomes of discharge disposition, need for additional medications, and restraint use for patients who received inhaled loxapine compared with patients receiving traditional antipsychotic drugs in the emergency department (ED).

METHODS: A retrospective chart review was conducted on all patients who presented to the ED with agitation and received antipsychotic therapy, including loxapine, ziprasidone, or haloperidol from December 1, 2014, through October 31, 2016.

RESULTS: The mean time from physician assignment to medical clearance was 7.9 hours for patients treated with inhaled loxapine versus 10.3 hours for controls (P < 0.01). Those who received inhaled loxapine were given significantly less benzodiazepines as additional rescue medications as compared with other antipsychotic medications (P < 0.01, 35.2% vs 65.1%). Additionally, restraints were utilized less frequently in the loxapine group (P < 0.01, 1.8% vs 19.8%).

CONCLUSIONS: Treating patients with agitation due to psychotic episodes in an ED setting with inhaled loxapine versus haloperidol or ziprasidone was associated with significantly improved treatment outcomes, suggesting that inhaled loxapine may be a more effective and rapid treatment option.
