Betahistine is a histamine analog that primarily acts as an H1 receptor agonist and H3 receptor antagonist. It improves microcirculation in the inner ear by vasodilation of the stria vascularis. This leads to reduced endolymphatic pressure, which is beneficial in Ménière’s disease. It enhances vestibular compensation by increasing neurotransmitter release. Clinically, it is used to manage vertigo, tinnitus, and balance disorders associated with vestibular dysfunction.
