Mechanism of action
Betavert is a synthetic analogue of histamine.
Betahistine acts mainly on the histamine H1 and H3 receptors of the inner ear and the vestibular nuclei of the CNS. Through direct agonistic action on the H1 receptors of the vessels of the inner ear, as well as indirectly through the impact on the H3 receptors, improves microcirculation and permeability of the capillaries of the inner ear, normalizes the pressure of the endolymph in the maze 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 nuclei of the vestibular nerve. Normalizes conduction in neurons of the vestibular nuclei at the level of the brain stem.
The clinical manifestation of these properties is to reduce the frequency and intensity of dizziness, reduce tinnitus, improve hearing in case of a decrease.
Rapidly absorbed, low plasma protein binding. The time to reach Cmax is 3 hours. It is almost completely excreted by the kidneys as a metabolite (2-pyridylacetic acid) within 24 hours. T1 / 2 - 3-4 hours.
