The Montefiore Metoclopramide Study
A Phase 4 study testing metoclopramide 10 mg, Diphenhydramine 25 mg and Metoclopramide 20 mg in people with Nausea and Extrapyramidal Symptoms, run by Montefiore Medical Center at 1 site in United States.
Trial summary
Metoclopramide is a dopamine antagonist frequently used for the treatment of nausea, vomiting, and migraine headaches in Emergency Departments. However, little research has focused on the optimal dose of metoclopramide for treatment of nausea in the emergency department. Read more about this study

About this study
Official title: A Randomized, Facorial Design Study to Optimize the Dose of Parenteral Metoclopramide
Metoclopramide is a dopamine antagonist frequently used for the treatment of nausea, vomiting, and migraine headaches in Emergency Departments. However, little research has focused on the optimal dose of metoclopramide for treatment of nausea in the emergency department. We propose a randomized, double-blind, placebo controlled trial to investigate the optimal dose of metoclopramide for treatment of nausea.
Read the detailed description
The most effective dose of metoclopramide for treatment of nausea in the emergency department setting has not been thoroughly investigated. One pilot study among emergency department patients in Australia found no statistical difference between 10 mg and 0.4 milligrams/kilogram; another investigation suggests that the anti-emetic effect of 10 milligrams of metoclopramide is no more effective than placebo. In contrast, investigations focusing on chemotherapy patients and post-operative patients suggest that higher dosage metoclopramide is more effective in treating nausea and vomiting. This emergency department study will compare the anti-emetic efficacy of 10 milligrams and 20 milligrams of metoclopramide by using the visual analog scale.
In addition to evaluation of dose, we will evaluate one of the most common side affects of metoclopramide, akathisia. Akathisia is characterized by a subjective component of restlessness and an objective component in the form of the inability to remain motionless. Anti-cholinergic medications are known to reduce extrapyramidal symptoms such as akathisia when dopamine function is impaired in the basal ganglia. In fact, the use of diphenhydramine has been shown to reduce the incidence of akathisia in patients receiving a different anti-emetic, prochlorperazine. However, no research has focused on the use of anti-cholinergic medications to reduce metoclopramide induced akathisia. This investigation will assess the use of 25 mg of diphenhydramine in preventing metoclopramide induced akathisia in ED patients being treated for nausea/vomiting.

What is being measured
The primary outcome is the main question the study is designed to answer.
Nausea Scale
Patients were asked to report their level of nausea on a scale for 0 to 10, with 0 representing no nausea and 10 the worst nausea imaginable
Measured: 60 minutes
Secondary outcomes (1)
Number of Participants With Akathisia
The akathisia outcome was reported as follows: Either development of akathisia as measured using the Short Akathisia Instrument (Vinson DR. Journal of Emergency Medicine. 2006; 31:139-145)or use of rescue medication for treatment of akathisia.The short akathisia instrument briefly measures subjective and objective restlessness.
Measured: 60 minutes

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing metoclopramide 10 mg, Diphenhydramine 25 mg and Metoclopramide 20 mg in people with Nausea and Extrapyramidal Symptoms, run by Montefiore Medical Center 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 4 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 31 Dec 2012. 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?
Yes. Results are posted in the registry (first posted 31 Dec 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Nausea Scale (time frame: 60 minutes). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 31 Dec 2012; AzTrials last refreshed its copy on 28 Oct 2026.
