Аннотация
PROBLEM: Menieres disease is an inner ear disorder characterized by episodes of spontaneous vertigo, fluctuating hearing loss and tinnitus. Betahistine has been used to reduce intensity and frecuency of vertigo attacks, but there is controversy regarding its effectiveness.
METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach.
RESULTS AND CONCLUSIONS: We identified four systematic reviews including 12 trials overall. We concluded betahistine might reduce the number of attacks, vertigo intensity and lead to a symptomatic improvement according to global judgement in patients with Menieres disease, but the certainty of evidence is low. On the other hand, it probably does not have significant adverse effects.
