Abstract:
Gastritis, characterized by gastric mucosal inflammation, is a common gastrointestinal disorder with diverse etiologies, such as Helicobacter pylori infection, nonsteroidal anti-inflammatory drugs use, and autoimmune conditions. Pharmacological treatment aims primarily to heal the mucosa and resolve symptoms, and such treatments include mucoprotective agents, histamine-2 receptor antagonists (H2RAs), proton pump inhibitors (PPIs), and potassium-competitive acid blockers (P-CABs). Mucoprotective agents enhance gastric mucosal protection through multiple mechanisms, such as by promoting mucosal regeneration, reducing inflammation, and mitigating oxidative stress. Clinical trials have highlighted the effectiveness of these agents in promoting endoscopic healing and ameliorating symptoms, underscoring the clinical significance of these agents. H2RAs have been extensively used to manage gastritis due to their proven efficacy in reducing gastric acid secretion and promoting mucosal healing. Additionally, PPIs along with newer P-CABs provide robust acid suppression and have shown the ability to rapidly relieve symptoms, thus increasing the number of available treatment options. Since each pharmacological agent offers distinct therapeutic benefits, treatment should be selected based on an individual patient's needs and clinical context.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
