Thanks for query. Helicobacterial pylori is a microorganism which is responsible for a significant proportion of gastritis and peptic ulcer. Pantoprazole
helps to reduce acidity and releives the symptoma. In long term use, it may help to reduce population of helicobacter pylori
. Eradication of H.Pylori requires treatment with amoxycillin,clarithromycin
for aperiod of 14 days along with lansoprazole
or pantoprazole. As fer as my knowledge is concerned, this should not affect the test result. You may also consult with a gastroenterologist regarding performing upper G.I endoscopy followed by rapid urease tast. Also , pantoprazole 's effect do not last for more than 24 hours.Hope,I satisfied your queries.
