The Impact of Betahistine versus Dimenhydrinate in the Resolution of Residual Dizziness in Patients with Benign Paroxysmal Positional Vertigo : A Randomized Clinical Trial
OBJECTIVES: The aim of this study was to compare the effects of betahistine with dimenhydrinate on the resolution of residual dizziness (RD) of patients with benign paroxysmal positional vertigo (BPPV) after successful Epley maneuver.
METHODS: In this double-blind, randomized clinical trial, patients with posterior semicircular canal type of BPPV were included. After execution of the Epley maneuver, patients were assigned randomly to one group for 1 week: betahistine, dimenhydrinate or placebo. The primary outcomes were scores of the Dizziness Handicap Inventory (DHI) and the modified Berg balance scale (mBBS). All patients were asked to describe the characteristics of their subjective residual symptoms. Binary logistic regression analysis was performed to examine the predictors of improved RD. All analyses were conducted using SPSS 19.0.
RESULTS: In total, 117 patients (age range: 20-65 years) participated in this study. After the Epley maneuver, 88 participants had RD. After the intervention, 38 patients exhibited an improved RD. Less than 50% of participants in the three groups showed mild to moderate dizziness handicap. However, there was no significant difference between mBBS scores of groups before or after the intervention. Logistic regression was shown that patients with receiving betahistine were 3.18 times more likely to have no RD than the placebo group. Increasing age was associated with a decreased likelihood of improving RD (P = .05).
CONCLUSION: The analysis of data showed that the use of betahistine had more effect on improving RD symptoms. We recommended future studies using objective indicators of residual dizziness.
