Prevacid

A specific inhibitor of H + – K + – ATPase (represses the activity of the enzyme, that accelerates the exchange of hydrogen ions). Acting in the final phase of secretion (separation) of hydrochloric acid in the stomach, the drug reduces the acid production, regardless of the nature of the stimulating factor. Duodenal ulcer exacerbation, reflyuksezofagit (inflammation of the esophagus caused by throwing gastric contents into the esophagus).

Carafate

Gastroprotective preparation that creates a protective pellicle, increases the synthesis of Pg, reduces the activity of pepsin and salt binds bile acids. Carafate dissolves in an acidic medium, forms a sticky paste-like polymer that has alkaline properties. Being in the stomach and duodenum 12, changes into a polyanion with a lot of free negative charges that form strong bonds with the positive radical of protein exudate (albumin, fibrinogen) mucosa.

Prilosec

Lowers the secretion of hydrochloric acid in the stomach, as an inhibitor of “proton pump”(process of the exchanging of hydrogen ions). The mechanism of antisecretory action associated with inhibition (suppression of) the enzyme H-K-ATPase (an enzyme that accelerates the exchange of hydrogen ions) in the cell membranes of the gastric mucosa, which leads to blocking of the final stage of formation of hydrochloric acid.
