M-Zacid reflux disease: a digestive disorder involving lower esophageal sphincter (LES) dysfunction, which allows acid to flow from the stomach back into the esophagus. See also gastroesophageal reflux disease (GERD).
amoxicillin: an antibiotic used to treat infections.
antacid: an agent that counteracts or neutralizes acid in the stomach.
antibiotic: a medication which is used to treat infections.
barium sulfate: a substance that can be safely used in diagnostic studies of the gastrointestinal tract.
Barrett's esophagus: a condition that occurs when the lining of the lower esophagus changes to resemble the lining of the intestine.
biopsy: the process of removing tissue for diagnostic tests.
duodenal ulcer: an internal sore in the lining of the first portion of the small intestine (duodenum).
duodenum: the first part of the small intestine.
endoscope: an instrument used to examine the inside of hollow organs, such as the esophagus, stomach, and duodenum.
endoscopy: a procedure used to examine the inside of the upper gastrointestinal tract by passing a small tube with a camera on the end into the body.
esophagitis: inflammation of the esophagus.
esophagus: part of the digestive system that provides a passage from the pharynx to the stomach.
gastric ulcer: a sore in the lining of the stomach.
gastroesophageal reflux disease (GERD): a digestive disorder involving lower esophageal sphincter (LES) dysfunction, which allows acid to flow from the stomach back into the esophagus. See also
acid reflux disease.
gastrointestinal: pertaining to the stomach and the intestines.
heartburn: a pain or burning sensation in the chest usually resulting from the backing up, or refluxing, of stomach acid into the esophagus; also known as pyrosis, Greek for "a burning."
H. pylori (Helicobacter pylori): pronounced HELI-co-back-ter pie-LORRIE abbreviated
H. pylori, a bacterium found in the stomach that can cause
ulcers.
inflammation: swelling, pain, warmth and redness of tissue, due to injury.
lansoprazole: the active ingredient in PREVACID.
larynx: part of the respiratory tract that contains the vocal chords.
lower esophageal sphincter (LES): a muscular valve found between the esophagus and the stomach, which opens and then closes to pass food and fluids into the stomach and then closes.
NSAID: NSAIDs (nonsteroidal anti-inflammatory drugs) are medications, such as aspirin, ibuprofen, and naproxen. Commonly used to treat arthritis pain.

polyp: a growth of tissue that protrudes from a mucous membrane.
PREVACID (lansoprazole): PREVACID contains the active ingredient lansoprazole. Prevacid is a
proton pump inhibitor which blocks the final stage of acid production in the stomach.
PREVPAC (lansoprazole/clarithromycin/amoxicillin): PREVPAC is a convenient daily dose pack that contains a multiple-drug treatment to eliminate
Helicobacter pylori to reduce the risk of duodenal
ulcer recurrence.
reflux: a backflow of contents.
stricture: the narrowing of a hollow structure, such as the esophagus.
ulcer: a lesion of tissue, like an open sore.
