Pharmacological action
Betaserc – improves microcirculation.
Pharmacodynamics
Betaserc (betahistine) acts primarily 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, and also indirectly through exposure to H3 receptors it improves microcirculation and capillary permeability, normalizes endolymph pressure in the labyrinth and cochlea. However, betahistine increases blood flow in the basilar arteries. Betaserk ® also has a pronounced central effect due to the influence of the vestibular nerve nuclei on the H3 receptors. Normalizes the conductivity in neurons of the vestibular nuclei at the level of the brain stem. A 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.
