E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Ménière’s disease is a disorder of the inner ear membranous labyrinth characterized by paroxysmal vertiginous attacks, fluctuating sensorineural hearing loss, aural fullness, and tinnitus .The underlying pathophysiology of Ménière’s disease is commonly seen in a hydrops of the endolymphatic space of the membranous labyrinth, resulting in recurrent ruptures of the endolymphatic sac and spillage of potassium-rich fluid into the perilymphatic space. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Investigation of the effect of high-dose (3x48mg/d), low dose (2x24mg/d) betahistin and placebo on the number of vertigo attacks during the last 3 months of the 9-month treatment period. |
|
E.2.2 | Secondary objectives of the trial |
Investigation of the effect of high-dose (3x48mg/d), low dose (2x24mg/d) betahistin and placebo on the number of vertigo attacks during the last 3 months of the total follow-up period; median duration of vertigo attacks, median severity of vertigo attacks during the last 3 months of the treatment period and the last 3 months of the total follow-up period; change of peripheral vestibular function, tinnitus intensity, effect of tinnitus on quality of life, subjective hearing loss, objective hearing loss – determined by acoustic evoked potentials, change of handicap / impairment due to vertigo or dizziness – assessed by the Dizziness Handicap Inventory (DHI) and the Vestibular Disorders Activities of Daily Living (VADL) score – between baseline, 9-month and 12-month follow-up visit. |
