Mechanism Of Action Of Valsartan, Amlodipine & Hydrochlorothiazide
Valsartan is an angiotensin II receptor blocker (ARB). It works by blocking a substance in the body that causes blood vessels to constrict.
As a result, Valsartan relaxes the blood vessels. This lowers blood pressure and increases the supply of blood and oxygen to the heart.
Amlodipine inhibits calcium ion influx across cell membranes, with a greater effect on vascular smooth muscle cells. This causes vasodilation and a reduction in peripheral vascular resistance, thus lowering blood pressure.
Hydrochlorothiazide inhibits sodium chloride transport in the distal convoluted tubule. More sodium is then excreted in the kidney with accompanying fluid.
Thus it increases urine excretion, which by turn decreases blood volume and finally blood pressure.
On long-term usage, thiazide diuretic (TZD)-mediated chronic reduction of arterial pressure is thought to occur through decreased total peripheral vascular resistance.
Therapeutic Indications Of Exforge HCT 5/160/25 Tablets
Treating high blood pressure (hypertension) in adult patients when monotherapy with amlodipine, valsartan, or hydrochlorothiazide is not sufficient.
High blood pressure is a common condition in which the long-term force of the blood against your artery walls is high enough that it may eventually cause health problems, such as heart disease.
Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions.
