Chemical structure and formulation
Betahistine hydrochloride is known for its structure, C8H12N2.HCl, which makes it suitable for different methods of administration, such as tablets or liquid solutions.
Pharmacological properties
- Boosts histamine turnover and release.
- It helps regulate the pressure within the inner ear fluid.
III. Mechanism of Action: How Betahistine Hydrochloride Works
Understanding the pharmacodynamics
Betahistine works by imitating histamines effects attaching to H1 and inhibiting H3 receptors in the inner ear and central nervous system. This process encourages blood vessel dilation. Helps regulate the firing rates of neurons.
The role in vestibular compensation
This medication helps restore balance by speeding up vestibular compensation, which's the brains adjustment to inner ear changes after injury or illness.

Betahistine weight loss
The ability of betahistine to aid in weight loss is connected to its impact on the hypothalamus and liver, leading to increased thermogenesis and decreased food consumption. A randomized controlled trial involving 48 women who were treated with both olanzapine and betahistine showed a 37% decrease in average weight gain among those in the betahistine group.
Betahistine withdrawal
After stopping Betahistine for a day, the patient's posture returned to normal. She felt fine. It's important not to stop taking Betahistine even if you start feeling better, as symptoms could come back or worsen in certain situations.
