Betahistine is primarily indicated for which condition?

Betahistine is primarily indicated for Meniere's disease, a condition that affects the inner ear and can lead to episodes of vertigo, hearing loss, tinnitus, and a feeling of fullness in the ear. The drug works by improving blood flow in the inner ear, which can help reduce the frequency and severity of vertigo attacks associated with Meniere's disease.

While betahistine may help alleviate symptoms related to vertigo due to Meniere's disease, its specific use is for the management of that condition rather than for vertigo in general or migraines, which are treated using different therapeutic approaches. Additionally, hypotension is not a condition that betahistine is indicated for; it does not serve to raise blood pressure or address related symptoms. Thus, the indication for Meniere's disease best aligns with the pharmacological properties and clinical studies surrounding betahistine.
