Candesartan

Candesartan is an angiotensin II receptor blocker widely used for hypertension and as adjunct therapy in heart failure with reduced ejection fraction. Simson Pharma's Candesartan reference standard and impurities support the high-volume compendial testing this established ARB requires.
