Oral Rapidly Dissolving Olanzapine for Acute Primary Headache in the Emergency Department Setting: A Feasibility Trial

This trial is a prospective, randomized, feasibility trial with the primary aim of comparing how well oral rapidly dissolving olanzapine controls primary headache pain when compared to the current treatment strategies used in emergency departments which often require intravenous or intramuscular medications.

Study Overview

Detailed Description

Primary Question:

Does oral rapidly dissolving olanzapine provide efficacious analgesia in patients with acute headache of non-organic origin (primary headache) who come to the ED for abortive therapy when compared to current standard of care?

Secondary Aim:

Additionally, the study will aim to see if oral rapidly dissolving olanzapine decreases 1) duration of ED length of stay and 2) need for IV access when compared to the current standard of care.

This is a prospective, randomized, convenience sample, feasibility trial to test for non-inferiority of oral rapidly dissolving olanzapine versus current emergency department standard of care in providing symptomatic relief to patients presenting with primary headache.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Pain Scores Based on Patient Questionnaire
Time Frame: baseline, 30, 60, and 90 minutes post drug administration
Change in patient reported pain score from baseline using the Numeric Pain Rating Scale (PNRS) Minimum score = 0 Maximum score = 10 Lower score indicates lower pain level, with zero indicating no pain and 10 indicating the worst pain imaginable.
baseline, 30, 60, and 90 minutes post drug administration
