About this study

Official title: A Randomized Controlled Trial of Ondansetron and Promethazine in the Treatment of Nausea and Vomiting in the Emergency Department

This was a trial comparing two commonly used medications for nausea and vomiting, ondansetron and promethazine, in the Emergency Department.

Read the detailed description

Nausea and vomiting are common complaints in the emergency department (ED). There are many pharmacologic agents used for the treatment of these complaints. None are new nor experimental. Very little research has been done in the ED setting to determine which of these agents is most effective with the least adverse effects. Our own previous research found that droperidol but not prochlorperazine and metoclopramide is more effective than placebo. Because of the recent FDA black box warning added to droperidol, the use of this agent has suddenly ceased in many EDs. Promethazine remains a very commonly used antiemetic in many EDs but one recent study found it less effective than prochlorperazine which was in turn found no more effective than placebo in our own study. As a result many physicians have turned to ondansetron, a newer and more expensive agent. Experience among anesthesiologists and oncologists has shown ondansetron to be highly effective with a minimum of adverse effects. These patient populations, however, are very different from those found in the ED. It is our hypothesis that promethazine and ondansetron are equally effective for the ED treatment of unselected patients with nausea and vomiting with similar rates of adverse effects.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ondansetron and promethazine in people with Nausea and Vomiting, run by University of New Mexico at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Feb 2007. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Reduction in nausea on a VAS.. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00429832, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Feb 2007.
