Nausea and vomiting is a common complaint in the emergency department. Treatment is important for many reasons. In addition to patient comfort, there are adverse effects secondary to vomiting such as dehydration, metabolic alkalosis, Mallory-Weiss tears, and aspiration. Two mediations common used for nausea in ED patients include Ondanesetron and Metoclopramide.

Condition Intervention Phase
Nausea Vomiting Drug: Ondansetron Drug: Metoclopramide Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Care Provider)
Primary Purpose: Treatment
Official Title: Ondansetron 4 mg vs. 2 mg vs. Metoclopramide 10 mg for Nausea and Vomiting in the Emergency Department: A Randomized, Double-Blind Clinical Trial

Primary Outcome Measures:
  • To delineate whether a high vs low dose of Ondansetron in better as opposed to an alternate medication -- Metoclopramide in the ED setting for uncomplicated nausea and vomiting. [ Time Frame: 30 minutes ]

Enrollment: 137
Study Start Date: November 2005
Study Completion Date: December 2006
Primary Completion Date: December 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1 Drug: Ondansetron
Other Name: Ondansetron 2 mg IV
Active Comparator: 2 Drug: Ondansetron
4 mg
Other Name: Ondansetron 4 mg IV
Active Comparator: 3 Drug: Metoclopramide
10 mg IV
Other Name: Metoclopramide 10 mg IV

Detailed Description:
This study will compare Ondansetron 4 mg vs 2 mg vs Metoclopramide 10 mg to look for efficacy in nausea and vomiting treatment for patients in the ED with many different causes. We will also look for cost effectiveness as well, since Metoclopramide is much less expensive than Ondansetron, which is less expensive at lower doses. There is little research about nausea medication in the ED literature even though these medications are used frequently in the ED for many causes of nausea.
