Tasosartan is primarily used in the treatment of hypertension, helping to lower high blood pressure by blocking the action of angiotensin II, a substance in the body that causes blood vessels to tighten. This effect allows blood vessels to relax and widen, improving blood flow and reducing the strain on the heart. Additionally, it may be explored for its potential benefits in managing heart failure and protecting kidney function in patients with diabetes, due to its role in regulating blood pressure and reducing proteinuria. Its application is particularly relevant in patients who require long-term management of cardiovascular risks.
