Study summary

Background: Vertigo as acute symptom seem to be one of most common presentation in ED, can be treated in ED with multiple medication . Objective: This study aimed to compare the therapeutic efficacy of metoclopramide, promethazine and prochloroperazine in patients presenting with signs and symptoms suggestive of acute peripheral vertigo to the ED . Methods: A 3-arm multi-center, randomized, triple-blind, controlled study comparing three treatments for acute vertigo in three medical centers : AlNahdha hospital Oman , Sohar Hospital Oman and AFH hospital Oman. Oman From February 2022 to August 2024.

Read the detailed description
  • Background Vertigo is one of most ED visit symptoms, It can be due to central or peripheral cause. The most frequent three reasons for vertigo are acute peripheral vestibulopathy (vestibular neuritis, labyrinthitis), Meniere's disease, and benign paroxysmal positional vertigo (BPPV). Usually ED doctors started with Epley maneuver for relief of symptoms and then started with medication.
  • Objective:

This study aimed to compare the therapeutic efficacy of metoclopramide, promethazine and prochloroperazine in patients presenting with signs and symptoms suggestive of acute peripheral vertigo to the ED .

  • Research methods: This will be done by assessing the Best medication can be used to treat peripheral vertigo with least side effect through Randomized triple blinded analysis will use 3 medications. All medications will be saved in similar syringe with white paper cover and labeled as A,B, C .The treating EM Doctor will prescribe medication as anti-vertigo then one of covered medication will be randomly taken among 3 medication groups. Target population will be all patient in age group (18-60) years visiting the emergency department at Al Nahdha hospital, AFH and Sohar hospital who complain of peripheral vertigo after assessment and excluding central cause. Ethical approval will be applied for through the OMSB (Ministry of health ethical committee)

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

Interventions

  • DrugMetoclopramid ( 10mg), IM promethazine (25mg) , IM prochloroperazine( 12.5mg)

    Each patient with vertigo symptoms will be registered in vertigo list after written consent taken. The ED doctor will take one paper from the vertigo list box and will write the case there including patient ID, date, age and symptoms. Assessment (VAS \& EEV) will be done in the pre- medication 0 min, and at 60 mins posts anti-vertigo medication. The medication will be provided blindly through the pharmacy. Any possible medication side effect and any possible further work up done for patient will be involved in each paper as ED doctor will put a tick near each point. Score will be written in papers as per patient evaluation of their symptoms grade from 1-10. The need for rescue medication ( betahisten or ondansetron ) will be recorded in the paper or is need eply manuver. Principle investigator in each centre will be responsible to collect the papers for analysis by end of each weeks.

    Also known as: Metoclopramid ( 10mg), IM phenergan (25mg) , IM stemetil( 12.5mg)

What researchers measure

Primary outcomes

  1. medication effectiveness in peripheral vertigo.

    1. Compare the effects of IM metoclopramide or IM promethazine or IM prochloroperazine in three randomizing groups in the treatment of peripheral Vertigo in emergency setting using Visual Analogue Scale taken from visual vertigo analogue scale/adapted from Longridge et al.,2002. (Nausea and vertigo scores as measured by Visual Analogue Scale that include patient assessmet of his symptoms in view of vertigo/ nausea/ vomiting)

    Time frame: 1hr

Secondary outcomes

  1. The need of rescue medication/ appearing of side effects.

    The need for more rescue medications to relive the symptoms or for any appearing side effect at the time frame of assessment for vertigo symptom/ side effects like extrapyramidal side effect.

    Time frame: 0-1hr

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 16, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
