Valsartan is an angiotensin II receptor blocker (ARB) used primarily to treat high blood pressure (hypertension), heart failure, and to improve survival after a heart attack. As an active pharmaceutical ingredient (API), valsartan is the main component in various brand-name medications such as Diovan.
Like other APIs, undergoes rigorous testing and quality control measures to ensure its safety, efficacy, and purity. Pharmaceutical companies must adhere to regulatory standards set by agencies such as the FDA (in the United States) or the EMA (in Europe) to manufacture and distribute medications containing valsartan.
