Brief Summary

The study team proposes a randomized, double-blind, RCT to address the following goal: to determine the relative efficacy and adverse event profile of fosaprepitant compared to the standard of care antiemetic ondansetron. Fosaprepitant and its active metabolite aprepitant are a relatively new class of antiemetic that exclusively acts in the central nervous system by blocking neurokinin (NK-1) which is a key signaling molecule in the centrally mediated aspects of the vomiting reflex. Currently, fosaprepitant and aprepitant both have only two United Stated Food and Drug Administration (USFDA) approved indications for nausea and vomiting: chemotherapy-induced and postoperative. Neurokinin inhibitors are highly effective and generally well-tolerated. Therefore, this class of medication may be a more appropriate medication for the millions of patients with nausea and vomiting that seek care in EDs. Intravenous fosaprepitant is converted to the active metabolite aprepitant on the order of minutes and is significantly cheaper to procure at this time. The outcome for the efficacy analysis will be no need for additional medication to treat nausea and vomiting within 2 hours of investigational medication administration. The primary outcome for the tolerability analysis will be the development of any new symptom within 2 hours of medication administration.

Outcome Measures

Primary Outcomes (1)

• Sustained Relief from NV

  Sustained relief from nausea and vomiting will be determined by the intensity of nausea reported by participants following administration of antiemetic. Intensity of nausea will be reported as either None, Mild, Moderate, or Severe. The number/percentage of participants reporting each degree of nausea intensity will be summarized Sustained relief of nausea and vomiting requires a patient to present with a nausea intensity of either "severe" or "moderate," which is then reduced by treatment to at least "mild" or "none," within two hours of medication administration, and then maintained at "mild" or "none" level for the entire 24-hour period following medication administration without the use of rescue medication.

  24 hours (measured every 15 minutes for the first 2 hours, then hourly after that until disposition; reassessed at 24 hours)

Secondary Outcomes (11)

• Severity of Nausea

  24 hours (measured every 15 minutes for the first 2 hours, then hourly after that until disposition; reassessed at 24 hours)

• Need for rescue antiemetic medication

  2 hours (assessed at the 2 hour mark after administration of the intervention)

• Medication Preference

  24 hours

• Functional disability

  24 hours (assessed prior to receiving intervention, at 2 hour point after receiving intervention, and 24 hours after intervention)

• Vomiting

  24 hours
