Belsar-M 5/20 mg is a prescription medication formulated to manage high blood pressure (hypertension). It combines two active ingredients: Amlodipine Besilate (5 mg), a calcium channel blocker, and Olmesartan Medoxomil (20 mg), an angiotensin II receptor blocker (ARB). This combination works synergistically to relax blood vessels, facilitating smoother blood flow and reducing blood pressure levels.
