Pharmacological action

Betaver is a synthetic analogue of histamine.

Pharmacodynamics

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

It has a pronounced central effect, being an inhibitor of the H3 receptors of the vestibular nerve nuclei. Normalizes the conductivity in neurons of the vestibular nuclei at the level of the brain stem.

The clinical manifestation of these properties is a decrease in the frequency and intensity of dizziness, a decrease in tinnitus, and an improvement in hearing if it is reduced.

Absorbed rapidly, binding to plasma proteins is low. The time to reach Cmax is 3 hours. It is almost completely excreted by the kidneys in the form of a metabolite (2-pyridylacetic acid) within 24 hours. T1 / 2 - 3-4 hours.
