Menaril 16: Each tablet contains Betahistine Dihydrochloride BP 16 mg.


Betahistine is a histamine analog that was developed following successful parenteral use of histamine in patients with Meniere\\\'s Syndrome. Betahistine relieves vertigo symptoms by improving circulation in the microvasculature of the inner ear which leads to a pressure reduction on the membranous labyrinth and relieves the symptoms of meniere's disease.


Meniere's disease and Meniere-like syndromes are characterized by attacks of vertigo, tinnitus and/or progressive loss of hearing, usually accompanied also by nausea and vomiting.
