Glaucoma Illustration showing open-angle glaucoma eye anatomy in cartoon style

Glaucoma is a chronic, progressive optic neuropathy characterized by retinal ganglion cell loss and characteristic optic nerve/visual field damage in which lowering intraocular pressure (IOP) slows progression across openโ€‘angle, angleโ€‘closure, and secondary forms. The only proven diseaseโ€‘modifying therapy is sustained IOP reduction via medications, laser trabeculoplasty, or surgery tailored to mechanism, severity, and risk, with … Read more

Drugs Used for Peptic Ulcer Disease (PUD)

by
peptic ulcer disease - PUD

Overview Peptic ulcer disease (PUD) encompasses ulceration of the gastric or duodenal mucosa due to an imbalance between aggressive factors (gastric acid, pepsin, Helicobacter pylori, bile, and nonsteroidal anti-inflammatory drugs [NSAIDs]) and mucosal defenses (mucus-bicarbonate barrier, prostaglandins, mucosal blood flow, epithelial restitution). Pharmacologic therapy aims to relieve symptoms, promote healing, prevent complications (bleeding, perforation, obstruction), … Read more

Pharmacology of Proton Pump Inhibitors

by
Proton Pump Inhibitors

Introduction Proton pump inhibitors (PPIs) have revolutionized the management of acid-related gastrointestinal (GI) disorders by rendering potent and long-lasting suppression of gastric acid secretion. Introduced in the late twentieth century, PPIsโ€”exemplified by omeprazole, lansoprazole, pantoprazole, rabeprazole, esomeprazole, and dexlansoprazoleโ€”effectively mitigate gastric hyperacidity, enabling healing of peptic ulceration and alleviation of reflux symptoms (Katzung, 2020). Used extensively for indications ranging from peptic ulcer disease (PUD) and gastroesophageal reflux … Read more

Treatment of Angina Pectoris: A Comprehensive Guide

by
angina pectoris

Pharmacologic treatment of angina pectoris relies on antianginal agents that improve the myocardial oxygen supplyโ€“demand balance for symptom control and on adjunctive therapies tailored to mechanism (obstructive, vasospastic, microvascular), heart rate, blood pressure, and comorbidities under contemporary chronic coronary syndrome guidelines. Core antianginal classes include nitrates, beta-blockers, calcium channel blockers, late sodium current inhibition (ranolazine), … Read more
