A newer PCAB vonoprazan with a faster and longer lasting action than revaprazan, and PPIs has been marketed in Japan (2013), Russia (2021), and the US (2023). [4] [5] [6] PPIs are among the most widely sold medications in the world. The class of proton-pump inhibitor medications is on the World Health Organization's List of Essential Medicines.
Ball-and-stick model of cimetidine, the prototypical H 2 receptor antagonist. H 2 antagonists, sometimes referred to as H2RAs [1] and also called H 2 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.
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 ]
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] Serious side effects may include osteoporosis, low blood magnesium, Clostridioides difficile infection, anaphylaxis, and pneumonia. [3] Use in pregnancy and breastfeeding is of ...

Like other PPIs, rabeprazole is absorbed into the blood stream at the site of the proximal small bowel. [55] Rabeprazole's mechanism of action involves crossing from the blood stream into the parietal cells of the stomach, which are the cells that are responsible for secreting hydrochloric acid (HCl). [11] At this point, rabeprazole is inactive ...
