How does betahistine help with vertigo?
How does betahistine work? When you have Ménière’s disease, your symptoms such as dizziness, hearing loss and ringing in the ears are probably caused by a build-up of fluid in the inner ear. Betahistine is thought to work by increasing blood flow to this part of your ear and to reduce the amount of fluid there.
What is the action of betahistine?
Betahistine has two modes of action. Primarily, it has a direct stimulating (agonistic) effect on H1 receptors located on blood vessels in the inner ear. It appears to act on the precapillary sphincter in the stria vascularis of the inner ear, thus reducing the pressure in the endolymphatic space.
How does medication for vertigo work?

Why is betahistine used?
