H2 antagonists, sometimes referred to as H2RAs[1] and also called H2 blockers, are a class of medications that block the action of histamine at the histamine H 2 receptors of the parietal cells in the stomach. This decreases the production of stomach acid. H 2 antagonists can be used in the treatment of dyspepsia, peptic ulcers and ...
Proton-pump inhibitor. Proton-pump inhibitors (PPIs) are a class of medications that cause a profound and prolonged reduction of stomach acid production. They do so by irreversibly inhibiting the stomach's H + /K + ATPase proton pump. [1] Proton-pump inhibitors have largely superseded the H 2 -receptor antagonists, a group of medications with ...
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 (GERD) and peptic ulcer disease. PPIs also can bind to other types of proton pumps such as those ...
Proton-pump inhibitors (PPIs) are a group of drugs whose main action is a pronounced and long-lasting reduction of gastric acid production. They are the most potent inhibitors of acid secretion available. The group followed and has largely superseded another group of pharmaceuticals with similar effects, but a different mode of action, called H ...
H2 blockers, short for histamine-2 blockers, are effective at blocking the production of stomach acid, so there’s less created during digestion. “They bind to the histamine-2 receptor in the ...
Sucralfate may be considered to have the advantage over H2-blockers and PPIs in this regard because sucralfate does not change the pH of gastric fluid. A majority of meta-analyses found that sucralfate therapy decreased the incidence of ventilator-associated pneumonia compared to H2-antagonists. [10]
Famotidine, sold under the brand name Pepcid among others, is a histamine H 2 receptor antagonist medication that decreases stomach acid production. [4] It is used to treat peptic ulcer disease, gastroesophageal reflux disease, and Zollinger-Ellison syndrome. [4] It is taken by mouth or by injection into a vein. [4]
Cimetidine is a histamine type 2 blocker, which also binds to the androgen receptor to inhibit its function." However, this antiandrogen activity of cimetidine is weak, and the clinical benefit of its use in women with hirsutism is minimal. Thus, this drug is not recommended for the treatment of hyperandrogenism.
