p3 Acid-Controlling Drugs ch.

These flashcards cover key concepts related to acid-controlling drugs and the gastrointestinal system.

Gastrointestinal System

A system responsible for ingestion, digestion, absorption, and excretion, beginning at the mouth and ending at the anus.

Digestion

The process of converting food into chemical substances used by the body.

Peristalsis

Wavelike movements in the intestines that push food through.

Hydrochloric Acid (HCl)

An acid produced in the stomach, essential for food breakdown and absorption.

Peptic Ulcer Disease

A condition primarily caused by H. pylori infections and stress-related mucosal damage.

Antacids

Basic compounds that neutralize stomach acid; they may contain aluminum, magnesium, calcium, or sodium.

Proton Pump Inhibitors (PPIs)

Medications that block the formation of HCl and reduce irritation of gastric mucosa.

Histamine 2 (H2) Receptor Antagonists

Drugs that reduce gastric acid secretion by blocking H2 receptors on parietal cells.

GERD (Gastroesophageal Reflux Disease)

A condition where stomach acid flows back into the esophagus, causing irritation.

Sucralfate (Carafate)

A mucosal protectant that adheres to ulcers, forming a protective barrier.

Simethicone (Mylicon)

An antiflatulent that helps relieve painful gas in the GI tract by merging gas bubbles.

Side Effects of Antacids

May include constipation (aluminum/calcium), diarrhea (magnesium), and rebound acidity.

Patient Teaching for PPIs

Includes instructions on timing of doses, avoiding certain foods, and proper administration.
