1. What is Betahistina Normon and what is it used for

Betahistina Normon belongs to a group of medicines called antivertigo medicines, and its active ingredient is betahistine dihydrochloride.

Betahistina is used to treat Meniere's Syndrome, which is a disorder characterized by the following symptoms: vertigo (with nausea and vomiting), hearing loss, and a sensation of noise inside the ear (tinnitus).

The active ingredient of this medicine is a histamine analogue that acts by improving circulation in the inner ear, thereby reducing pressure. The inner ear is one of the organs responsible for the sense of balance.
