Used in the treatment of hypertension, telmisartan sodium helps lower blood pressure by blocking the action of angiotensin II, a substance that causes blood vessels to constrict. This leads to relaxation of blood vessels and improved blood flow. It is particularly beneficial for patients with high cardiovascular risk, including those with type 2 diabetes or established cardiovascular disease. The sodium salt form enhances solubility, which may improve bioavailability and support consistent therapeutic effects. It is often prescribed for long-term management and may reduce the risk of heart attack and stroke.
