Mechanism of Action: The exact mechanism is complex and not fully known, but Betahistine is a partial agonist of histamine H1 receptors and a strong antagonist of histamine H3 receptors. It is believed to improve blood flow to the inner ear and also affect brain chemistry to reduce symptoms.

Indications: It is used to treat the symptoms of Ménière’s disease, including vertigo (dizziness), tinnitus (ringing in the ears), and hearing loss.
