📖 1. Antacids Mechanism

🔑 Key Concepts & Definitions

• Antacids: Basic substances that neutralize gastric acid, providing symptomatic relief in acid-related disorders.
• Neutralization Reaction: The chemical process where antacids react with hydrochloric acid (HCl) to produce water and salt, increasing gastric pH.
• Gastric pH: The measure of acidity in the stomach; normal gastric pH ranges from 1.5 to 3.5.
• Acid Rebound: A phenomenon where gastric acid secretion increases after the effect of antacids wears off, potentially worsening symptoms.
• Rapid Onset: Antacids act quickly, usually within minutes, to neutralize existing stomach acid.
• Duration of Action: The period during which antacids maintain elevated gastric pH, typically 1-2 hours.
