Candesartan methyl ester is a key chemical intermediate used in the synthesis of Candesartan, an angiotensin II receptor blocker (ARB) medication primarily for treating hypertension (high blood pressure). It serves as a precursor in pharmaceutical manufacturing processes, where it is converted into the active drug form. Candesartan helps relax blood vessels, improve blood flow, and reduce the risk of stroke, heart attack, and kidney problems in patients with cardiovascular conditions. It may also be used in heart failure management.
