Description | Betahistine is only found in individuals that have used or taken this drug. It is an antivertigo drug first used for treating vertigo assosicated with Meniere's disease. It is also commonly used for patients with balance disorders.Betahistine primarily acts as a histamine H1-agonist with 0.07 times the activity of histamine. Stimulating the H1-receptors in the inner ear causes a vasodilatory effect and increased permeability in the blood vessels which results in reduced endolymphatic pressure. Betahistine is believed to act by reducing the asymmetrical functioning of sensory vestibular organs as well as by increasing vestibulocochlear blood flow. Doing so aids in decreasing symptoms of vertigo and balance disorders. Betahistine also acts as a histamine H3-receptor antagonist which causes an increased output of histamine from histaminergic nerve endings which can further increase the direct H1-agonist activity. Furthermore, H3-receptor antagonism increases the levels of neurotransmitters such as serotonin in the brainstem, which inhibits the activity of vestibular nuclei, helping to restore proper balance and decrease in vertigo symptoms. |
