proton pump
1proton pump — n a molecular mechanism that transports hydrogen ions across cell membranes * * * the enzyme in the oxyntic cells of the stomach that causes acid secretion by producing hydrogen ions in exchange for potassium ions. * * * a system for transporting …
2Proton pump — This article is about proton pumps in general. For the proton P type ATPase, see proton ATPase. A proton pump is an integral membrane protein that is capable of moving protons across the membrane of a cell, mitochondrion, or other subcellular… …
3Proton pump inhibitor — Proton pump inhibitors (or PPI s) are a group of drugs whose main action is pronounced and long lasting reduction of gastric acid production. They are the most potent inhibitors of acid secretion available today. The group followed and has… …
4proton pump inhibitor — n any of a group of drugs (as omeprazole) that inhibit the activity of proton pumps and are used to inhibit gastric acid secretion in the treatment of ulcers and gastroesophageal reflux disease abbr. PPI * * * (PPI) an agent that inhibits the… …
5proton pump inhibitor — noun Any of several short term treatments for gastric and duodenal ulcers and for the eradication of the bacterium helicobacter pylori (abbrev PPI) • • • Main Entry: ↑proton …
6proton-pump inhibitor — a drug that reduces gastric acid secretion by blocking the proton pump within the oxyntic cells. Proton pump inhibitors include lansoprazole, omeprazole, and pantoprazole; they are used for treating gastric and duodenal ulcers, reflux… …
7proton-pump inhibitor — a drug that reduces gastric acid secretion by blocking the proton pump within the oxyntic (parietal) cells. Proton pump inhibitors include esomeprazole, lansoprazole, omeprazole, pantoprazole, and rabeprazole; they are used for treating gastric… …
8Discovery and development of proton pump inhibitors — Proton pump inhibitors (PPIs) block the gastric Hydrogen potassium ATPase (H+,K+ ATPase) and inhibit gastric acid secretion. These drugs have emerged as the treatment of choice for acid related diseases, including gastroesophageal reflux disease… …
9proton pump — noun Any protein in the membrane of a cell or mitochondrion whose function is to move protons across the membrane and thus establish an electrochemical potential …
