betahistine | Vestibo tablets 16 mg 30 pcs.

Latin name

Vestibo

Pharmacological action

Vestibo is a histamine-like, vasodilating.

Pharmacodynamics

It is a weak agonist of H1 receptors and a fairly potent antagonist of H3 receptors. Affects cochlear blood flow and the central vestibular apparatus. The action of betahistine includes: vasodilation in the inner ear (indirectly through H3 and H1 receptors), an inhibitory effect on vestibular nuclei (through H3 receptors) and the impulse activity of ampullary receptors. By direct agonistic action on the H1 receptors of the vessels of the inner ear and precapillary sphincters of the microvasculature located in the vascular strip (stria vascularis), as well as indirectly through the H3 receptors it improves microcirculation and capillary permeability, normalizes the pressure of the endolymph in the labyrinth and increases basilar artery. It has a pronounced central effect, being an antagonist of the H3 receptors of the vestibular nerve nuclei, it normalizes neuronal transmission in polysynaptic neurons of the vestibular nuclei at the level of the brain stem. By indirectly acting on H3 receptors, it increases the content of serotonin in the brain stem, which reduces the activity of the vestibular nuclei. Helps to eliminate disorders from both the vestibular and cochlear apparatus: reduces the frequency and intensity of dizziness, reduces tinnitus, helps to improve hearing in cases of decrease. It stimulates H1 receptors, therefore it does not have a sedative effect and does not cause drowsiness.

Pharmacokinetics

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