How does Vasodialation by beta histine helps

For treatment of Meniere’s how does Vasodialation by beta histine helps…you said in the lecture that it helps in reabsorption of Endolymph…but I cannot understand the phenomenon maam.

Betahistine improves the micro circulation in Stria vascularis by vasodilation and hence helps in reducing the endolymphatic pressure

thank you so much maam
