- Vertigo complaint is one of the common cause of patients who applied to emergency


- Patients who have applied to emergency services with vertigo complaint mostly have

nausea as an additionally symptom to this complaint and anti-emetic agents can be used in their treatments very often.

- The investigators purpose is to investigate the advantages of Dimenhydrinate and

metoclopramide to each other in the treatment of vertigo and the vertigo accompanied by nausea

Clinical Details

Official title: Comparison of Efficacy Dimenhydrinate and Metoclopramide in the Treatment of Nausea Due to Vertigo

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Factorial Assignment, Masking: Double Blind (Subject, Caregiver, Investigator), Primary Purpose: Treatment

Primary outcome: compare the effects of intravenous dimenhydrinate and metoclopramide in the treatment of nausea due to vertigo in emergency setting. (nausea and vertigo scores as measured by Visual Analogue Scale.)

Detailed description:

- Vertigo describes the illusion of being subject to an involuntary movement, usually

rotational, of the patient or the patient's surroundings which is caused by sudden tonic neural activity.

- The management and episodic treatment of patients with spontaneous vertigo related

nausea-vomiting symptoms are somewhat controversial in the emergency department setting.

- Patients admitted to the emergency department with complaints of vertigo in addition to

a large portion of the symptoms are accompanied by nausea and antiemetic agents are frequently used in the treatment.

- An ideal treatment should be rapid in onset and effective, and lack debilitating side


- Although a wide variety of classes of pharmacologic agents and modalities are used, the

emergency department treatment of acute spontaneous vertigo and associated with nausea- vomiting has not been well studied.

- It has been reported that the most commonly used medications for parenteral treatment

of vertigo and nausea-vomiting in emergency department are dimenhydrinate (DMT) and metoclopramide (MTP).

- It has a depressant action on hyper-stimulated labyrinthine function and antiemetic

effects, believed to be due to the antihistamine.

- Dimenhydrinate inhibits vomiting by affecting the histaminic receptor and cholinergic

receptor function center of vestibular nucleus in the central vestibular system.

- Dimenhydrinate reduces the symptoms of vertigo with depressant effects on the labyrinth

function by this means.


Minimum age: 18 Years. Maximum age: 65 Years. Gender(s): Both.
