Used primarily in the treatment of vertigo associated with Ménière's disease, it helps reduce the frequency and severity of symptoms such as dizziness, tinnitus, and hearing loss. It works by improving inner ear circulation and reducing pressure in the labyrinth, which helps balance sensory signals. Also used off-label for other balance disorders and in some cases of migraine-related dizziness. Its action as a histamine H1 receptor agonist and H3 receptor antagonist contributes to enhanced cerebral blood flow and neurotransmitter activity in vestibular pathways.
