Omeprazole is known as an oral anti-ulcer agent. Because of its characteristics of blocking the ending stage of gastric acid creation, it is categorized as a gastric acid pump inhibitor. It has an action of long duration and is actually effective, permitting for once-daily administration. Even with its effectiveness, this one is actually against helicobacter pylori and might be used in grouping with antibiotics.
Being concerned about long term use, it was accepted by FDA advisory committee and recommended it be allowed for upkeep therapy of cured erosive esophagitis. In April 1996, it was agreed for the cure of H.Pylori linked duodenal ulcer. It belongs to a novel class of antisecretory agents, switched benzimidazoles that suppress gastric acid discharge by obstructing the H+ /K+ ATPase pump that is on the secretory shallow of the parietal cell sheath. Subsequently, it impedes the discharge of hydrogen ions toward the gastric lumen. It impedes one basal and other stimulus-induced acid excretion. As a generic medication it is available.
Omeprazole is a good inhibitor of p-glycoprotein. Drugs that rely on an acidic environment of the stomach (such as ketoconazole or atazanavir) can be poorly absorbed, while to a greater extent acid-labile antibiotics may be absorbed than normal due to the alkaline stomach environment.
In 1978, Omeprazole was patented and in 1988, permitted for medical use. In World Health Organization’s it is in the List of Essential Medicines. In 2017, omeprazole was the seventh prescribed drug that most prescribe in the United State.
