Pharmacological action of

Betagistin acts mainly on the histamine H1 and H3 receptors of the inner ear and central vestibular nuclei. By direct agonistic action on the H1 receptors of the vessels of the inner ear, as well as indirectly through action on the NS receptors, it improves microcirculation and capillary permeability, normalizes the pressure of the endolymph in the labyrinth and cochlea. However, betahistine increases blood flow in the basilar artery.
