alprostadil
Alprostadil is produced endogenously and causes vasodilation by means of a direct effect on vascular and ductus arteriosus (DA) smooth muscle, preventing or reversing the functional closure of the DA that occurs shortly after birth. It is also used in maintaining a patent ductus arteriosus in newborns. Reference standards of Alprostadil API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
