This was a 3-month multicentre, open-label post-marketing surveillance study of betahistine (24 mg b.i.d. or 16 mg t.i.d.) in patients with vertigo of peripheral vestibular origin. Study endpoints comprised on-treatment changes in the Dizziness Handicap Index (DHI), Hospital Anxiety and Depression Score (HADS) and the Short-Form (SF)-36v2. Total DHI score improved 37.2 points (of a 100-point scale) following betahistine treatment. Corresponding improvements occurred in all three DHI scale domains (all p < 0.001 vs baseline). Betahistine therapy was also accompanied by progressive, significant improvements in both HADS-A and HADS-D scores (p < 0.001), and improvements in the distribution profiles of anxiety and depression scores. Significant improvements in the Physical Component Summary and Mental Component Summary scores of the SF-36v2 were recorded during betahistine treatment. Betahistine was generally well tolerated. A total of 76 adverse drug reactions (ADRs) were recorded in 49 patients (2.4%), of which 75 were classified as mild or moderate and 54 were possibly related to betahistine. ADRs led to study drug discontinuation in 17 patients. These data illustrate that treatment with betahistine 48 mg/day in patients with recurrent peripheral vestibular vertigo is associated with improvements in objective measures of health-related quality of life and satisfactory tolerability.
