Betahistine is a histamine analogue that acts as an H1 receptor agonist and a partial antagonist at H3 receptors. It is primarily used in the treatment of Ménière's disease and vestibular disorders to reduce vertigo, tinnitus, and hearing loss. The drug is approved for clinical use in several countries, though its approval status varies globally.
Pharmacokinetic parameters reported for healthy adult volunteers after single oral administration of betahistine dihydrochloride.
