Drug Classes for Treating Peptic Acid Disease in Gastrointestinal Pharmacology

This concept covers the major drug classes used to treat peptic acid disease within gastrointestinal pharmacology, organized by mechanism of action: antacids, H2 receptor antagonists, proton pump inhibitors, and mucosal protective agents. Each class is defined by its distinct pharmacological mechanism for reducing gastric acidity or protecting the gastric mucosa, along with associated pharmacokinetic properties, toxicities, and drug interactions relevant to therapeutic selection.
