Is pantoprazole as good as nexium (esomeprazole) or losec?

Yes, but...: A review in Journal of the American Pharmacists Association(Eval of Omeprazole,Lansoprazole,Pantoprazole,&Rabeprazole in Treatment of Acid-Related Diseases,J Am Pharm Assoc. 2000;40(1)),there is no difference amongst the proton pump inhibitors(pantoprazole, omeprazole, esomeprazole, rabeprazole). Clinically, we find some people respond better to one than another; if one doesn't work, try another.
