This category includes substances such as betahistine dihydrochloride, Vinpocentine or Ginkgo Biloba extract. Vasodilators generally comprise first aid drips. All these substances have a role to expand capillaries in the inner ear and improve the supply of auditory cells with oxygen and energy. Capillaries are, as we know, narrow after acoustic trauma, therefore, these substances may be quite effective in the early stages.
Betahistine is also used successfully in the treatment of Meniere's syndrome.
Ginkgo's positive effect on Tinnitus has not been documented.
