Betahistine dihydrochloride



Betahistine dihydrochloride (BH.2HCl) is an orally active histamine analog which has been used to control vertigo, lack of hearing and tinnitus related to Ménière’s disease. The mechanism of BH.2HCl is to reduce the pressure of the membranous labyrinth that results in enhancement of the microvasculature circulation and improves the signs of Ménière’s disease. Peroral administration undergoes extensive first-pass metabolism and gastric irritation in patients with peptic ulcer.

betahistine dihydrochloride vs betahistine hydrochloride

Betahistine is a medication used to treat vertigo and other balance disorders associated with Ménière’s disease. It is available in two different salt forms: betahistine dihydrochloride and betahistine hydrochloride.

The difference between betahistine dihydrochloride and betahistine hydrochloride lies in the counterion that is paired with the betahistine molecule.

  1. Betahistine Dihydrochloride: In this form, betahistine is paired with two molecules of hydrochloric acid (HCl) to form a salt. The chemical formula of betahistine dihydrochloride is C₈H₁₅N₃·2HCl. It is the most commonly used salt form of betahistine.
  2. Betahistine Hydrochloride: In this form, betahistine is paired with one molecule of hydrochloric acid (HCl) to form a salt. The chemical formula of betahistine hydrochloride is C₈H₁₅N₃·HCl. This salt form is less commonly used compared to betahistine dihydrochloride.

Both betahistine dihydrochloride and betahistine hydrochloride contain the same active ingredient, betahistine. They are used for the same therapeutic purposes and have similar pharmacological effects. The choice between the two salt forms may depend on factors such as availability, formulation considerations, and regional preferences.
