Olsertain-AM Tablet 15's, which is primarily used to treat high blood pressure, contains blood pressure-lowering drugs. Olsertain-AM Tablet 15's may be taken either on its own or in conjunction with other drugs that reduce blood pressure. A persistent illness known as hypertension or high blood pressure causes a strong force of blood against the arterial wall. As a result, it causes issues like heart disease and irregular pulse. Angiotensin receptor blocker Olmesartan and amlodipine are both found in Olsertain-AM Tablet 15s (calcium channel blocker). Olmesartan relaxes blood arteries by blocking the hormone angiotensin, which is how it functions. This makes the heart's pumping action more effective and the blood flow more smoothly. On the other hand, amlodipine works by relaxing the blood vessels.Disclaimer:For more information contact your physician.
