Telmisartan 40 mg tablets is a medication used to treat high blood pressure (hypertension) and to reduce the risk of cardiovascular complications. It belongs to a class of drugs called angiotensin II receptor blockers (ARBs), which work by relaxing blood vessels and lowering blood pressure. Telmisartan helps to control blood pressure, reducing the workload on the heart and improving overall cardiovascular health.
Telmisartan 40 mg tablets are commonly prescribed as a once-daily oral medication. It is used to treat adults and children 6 to 17 years of age with essential hypertension. This medicine may be used alone or in combination with other antihypertensive medicines, depending on the individual’s condition and the advice of their doctor.
By blocking the action of angiotensin II, telmisartan helps to dilate blood vessels, which lowers blood pressure. Lowering blood pressure is important in preventing heart attacks, strokes and other cardiovascular complications. Telmisartan has also been shown to have a beneficial effect on kidney function, making it a valuable treatment option for patients with certain kidney problems.
How does a Telmisartan 40mg tablet work?
Telmisartan 40 mg tablet is in a class of medicines called angiotensin II receptor blockers (ARBs). It works by blocking the effects of a hormone called angiotensin II, which normally causes blood vessels to narrow (constrict). By blocking the effects of angiotensin II, telmisartan helps the blood vessels to relax and widen, leading to a reduction in blood pressure.
Angiotensin II is a potent vasoconstrictor, which means that it causes blood vessels to constrict, resulting in increased resistance to blood flow. This increased resistance can lead to high blood pressure (hypertension), which puts strain on the heart and increases the risk of cardiovascular problems.
By blocking the angiotensin II receptor, telmisartan prevents the hormone from exerting its vasoconstrictive effects. This causes the blood vessels to dilate or widen, reducing the resistance to blood flow and subsequently lowering blood pressure. The relaxation of the blood vessels also helps to improve blood flow to the heart and other organs, reducing the workload on the heart and improving overall cardiovascular function.
