silodosin and its Impurities

An α1-adrenoceptor antagonist, Silodosin is used for the treatment of benign prostatic hyperplasia (enlarged protrate). Silodosin works by relaxing the muscles in the bladder and prostate so urine can flow easily. Reference standards of Silodosin API,and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
