1H-1-ethyl Candesartan Cilexetil is primarily used in the treatment of hypertension, or high blood pressure. It works by blocking the action of angiotensin II, a substance in the body that causes blood vessels to tighten, thereby helping to relax and widen blood vessels, which lowers blood pressure. This medication is often prescribed to reduce the risk of strokes, heart attacks, and kidney problems in patients with high blood pressure. It is typically taken orally in the form of a tablet, and the dosage may vary depending on the patient's condition and response to treatment. It is important for patients to follow their healthcare provider's instructions carefully and to continue taking the medication even if they feel well, as hypertension often has no symptoms. Regular monitoring of blood pressure and kidney function is usually recommended during treatment.
