Diuretics for the treatment of Ménière's disease or syndrome
Diuretics (drugs which reduce fluid accumulation in the body) are commonly used in the management of the symptoms of vertigo, hearing loss, tinnitus or aural fullness in patients with Ménière's disease. 'Endolymphatic hydrops' is an increase in the pressure of the fluids in the chambers of the inner ear and is thought to be the underlying cause of Ménière's disease. Diuretics are believed to work by reducing the volume (and therefore also the pressure) of these fluids. The authors of this systematic review carried out an extensive search but could not identify any randomised controlled trials of sufficient quality to include in the review. There is no good evidence about the effect of diuretics on the symptoms of Ménière's disease and further research is needed.

Abstract
Background
Ménière's disease is a disorder characterised by hearing loss, tinnitus and disabling vertigo. Diuretics are used to try and reduce the severity and frequency of episodes but there is little evidence behind this treatment.
Objectives
To assess the effect of diuretic treatment in patients with Ménière's disease.
Search strategy
We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 1 2005), MEDLINE (1966 to 2005), EMBASE (1974 to 2005), CINAHL and the metaRegister of Controlled Trials (mRCT) (up to 2005).
Selection criteria
Randomised controlled trials of diuretic versus placebo in Ménière's patients.
Data collection and analysis
One author identified studies which loosely met the inclusion criteria and full texts were retrieved. Two authors independently applied the inclusion criteria. Seven studies were excluded from the review due to inappropriate study design or absence of randomisation.
Main results
There were no trials of high enough quality to meet the standard set for this review.
Authors' conclusions
There is insufficient good evidence of the effect of diuretics on vertigo, hearing loss, tinnitus or aural fullness in clearly defined Ménière's disease.
