Overview

What is Merislon? 

Merislon is a medication primarily used to treat vertigo and balance disorders. Its active ingredient is betahistine, which is known to improve blood flow in the inner ear, potentially normalizing the pressure of the ear fluids. 

Merislon works by blocking the action of histamine at its receptors (H3 receptors in particular), leading to dilation of the vessels in the inner ear and improving microcirculation. The chemical structure of betahistine encourages this vasodilatory effect without typical anti-histaminergic side effects such as drowsiness, blurred vision and dry mouth. 

 

Global Name

The generic name of Merislon is betahistine. Betahistine is also marketed under various brand names, including Serc, Betaserc, and Veserc.
