Which medication would you commonly prescribe to alleviate symptoms of dizziness in patients with Meniere's disease?

1. Aspirin

2. Betahistine

3. Furosemide

4. Propranolol

The correct answer is: Betahistine

Betahistine is a common medication prescribed to alleviate symptoms of dizziness in patients with Meniere's disease. This condition is characterized by episodes of vertigo, tinnitus, hearing loss, and a sensation of fullness in the ear, often caused by abnormal fluid accumulation in the inner ear. Betahistine works by improving blood flow in the inner ear, thereby reducing the pressure and, consequently, the frequency and severity of vertiginous episodes. It acts as a histamine analog and enhances vestibular compensation, which helps stabilize balance and alleviate dizziness. The beneficial effects of betahistine on vertiginous symptoms make it a first-line treatment option for individuals suffering from Meniere's disease. Considering the other medications mentioned, they serve different purposes that are not primarily focused on managing dizziness caused by this specific condition. For example, aspirin is mainly used for pain and anti-inflammatory effects rather than targeting inner ear symptoms. Furosemide is a diuretic often used for fluid retention and high blood pressure, which may not directly address the vestibular symptoms associated with Meniere's disease. Propranolol is a beta-blocker frequently used for anxiety and migraine prophylaxis but does not specifically target vertigo symptoms related to inner ear disorders. Thus
