Rosemarie:  You are correct that Prilosec is omeprazole (I believe the
name was changed from Losec in the United States because Losec could be
confused with a couple of other brand names).  Prevacid is a newer
proton-pump inhibitor in the line of omeprazole, but I can't think of the
generic name at this time.  Alicia.  [log in to unmask]
