Description
(extracted from source data)
PHARMACODYNAMICS 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.
DESCRIPTION This is an orally delivered histamine receptor modulator that has weak agonist activity at histamine H1 receptors and more potent antagonist activity at the H3 receptor subtype . (GtoPdb)
DESCRIPTION Betahistine is a structural analog of histamine that acts as a weak partial postsynaptic histamine H1 receptor agonist and presynaptic H3 receptor antagonist, with no effect on postsynaptic H2 receptors. Betahistine, sold under the brand name Serc among others, is an anti-vertigo medication. It is commonly prescribed for balance disorders or to alleviate vertigo symptoms, e.g. those associated with Ménière's disease. (BOC Sciences Bioactive Compounds)
DESCRIPTION Betahistine is a histamine H3 receptors inhibitor with IC50 of 1.9 μM. (BOC Sciences Bioactive Compounds)
