The proton pump is the terminal stage in gastric acid secretion, being directly responsible for secreting H + ions into the gastric lumen, making it an ideal target for inhibiting acid secretion. [ citation needed ] Because the H,K-ATPase is the final step of acid secretion, an inhibitor of this enzyme is more effective than receptor ...
The H 2 receptor antagonists are a class of drugs used to block the action of histamine on parietal cells in the stomach, decreasing the production of acid by these cells. H 2 antagonists are used in the treatment of dyspepsia, although they have been surpassed in popularity by the more effective [1] proton pump inhibitors.
A derivative of timoprazole, omeprazole, was discovered in 1979, and was the first of a new class of drug that control acid secretion in the stomach, a proton pump inhibitor (PPI). [11] [12] Addition of 5-methoxy-substitution to the benzimidazole moiety of omeprazole was also made and gave the compound much more stability at neutral pH. [6]
A new study found a link between certain types of acid reflux medications and dementia. The study analyzed data from more than 5,000 people.
Omeprazole is a selective and irreversible proton pump inhibitor. It suppresses stomach acid secretion by specific inhibition of the H + /K +-ATPase system found at the secretory surface of gastric parietal cells. Because this enzyme system is regarded as the acid (proton, or H +) pump within the gastric mucosa, omeprazole inhibits the final ...
Pantoprazole is a proton pump inhibitor that decreases gastric acid secretion. [5] It works by inactivating (H+/K+)-ATPase function in the stomach. [9] [5] The study of pantoprazole began in 1985, and it came into medical use in Germany in 1994. [10] It is available as a generic medication.
Lansoprazole, sold under the brand name Prevacid among others, is a medication which reduces stomach acid. [4] It is a proton pump inhibitor (PPI), used to treat peptic ulcer disease, gastroesophageal reflux disease, and Zollinger–Ellison syndrome. [5] Its effectiveness is similar to that of other PPIs. [6] It is taken by mouth. [4]
Dexlansoprazole, is a medication which reduces stomach acid. [3] It is used to treat gastroesophageal reflux disease. [3] Effectiveness is similar to other proton pump inhibitors (PPIs). [4] It is taken by mouth. [3] Common side effects include diarrhea, abdominal pain, and nausea. [3]
