Telmisartan 80 mg Amlodipine 10 mg & Hydrochlorothiazide 25 mg Tablets helps to manage hypertension. Amlodipine is a calcium channel blocker that relaxes blood vessels by inhibiting the entry of calcium into the muscle cells of the heart and blood vessels. This reduces blood pressure and improves blood flow, making it easier for the heart to pump blood. Hydrochlorothiazide is a thiazide diuretic that helps the kidneys remove excess salt and water from the body. This reduces fluid buildup, lowers blood pressure, and helps decrease swelling (edema). Telmisartan is an angiotensin II receptor blocker (ARB) that relaxes blood vessels by blocking the action of angiotensin II, a hormone that causes blood vessels to constrict. This helps lower blood pressure and makes it easier for the heart to circulate blood.
