nebivolol and its Impurities
A cardioselective β1 receptor blocker, Nebivolol is used for the treatment of hyertension. It works by blocking the action of certain natural substances in your body, such as epinephrine, on the heart and blood vessels. This lowers the heart rate and blood pressure. Reference standards of Nebivolol API,and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
