OLPRES A 20/5 MG is a fixed-dose combination medication formulated to effectively manage essential hypertension (high blood pressure) in adults. Each tablet contains Olmesartan Medoxomil (20 mg), an angiotensin II receptor blocker (ARB), and Amlodipine Besylate (5 mg), a calcium channel blocker (CCB). This synergistic combination works by relaxing and widening the blood vessels, allowing for smoother blood flow and reducing the workload on the heart.
