The Parietal Cell: Mechanism of Acid Secretion The key player in acid secretion is a H+/K+ ATPase or proton pump located in the cannalicular membrane. 1  This ATPase is magnesium-dependent, and not inhibitable by ouabain. The current model for explaining acid secretion is as follows: 2  Hydrogen ions are generated within the parietal cell from dissociation of water.

- Omeprazole (oh mep' ra zole), like other PPIs, inhibits gastric acid production by binding to and inactivating the H+/K+-ATPase of gastric parietal cells, causing inhibition of the proton pump that transports H+ into the gastric lumen, the common final step in gastric acid production.ubMed Citation (Controlled trial of omeprazole vs cimetidine for 4 weeks in 132 patients with duodenal ulcer disease found no major side effects; one patient on omeprazole had rise of Alk P to 756 U/L, resolving with stopping therapy and 4 had minor AST elevations at the end of therapy [36-54 U/L]).

- water reabsorption will cause the concentration of the solute to rise to a point at which further water. reabsorption is prevented. This is the mechanism by which osmotic diuretics act (see below). Organic acid secretory systems are located in the middle third of the proximal tubule (S2 segment). These systems secrete a variety of organic acids (uric acid, nonsteroidal anti-inflammatory drugs NSAIDs, diuretics, antibiotics, etc) into the luminal fluid from the blood. These systems thus help deliver diuretics to the luminal side of the tubule, where most of them act. Organic base secretory systems (creatinine, choline, etc) are also present, in the early (S1) and middle (S2) segments of the proximal tubule. Loop of Henle

pantoprazole View Full Profile. Proton pump inhibitors are used for the treatment of conditions such as ulcers, gastroesophageal reflux disease (GERD) and Zollinger-Ellison syndrome that are caused by stomach acid. Lansoprazole, like other proton-pump inhibitors, blocks the enzyme in the wall of the stomach that produces acid.
