Step 1: Concept
Aluminium hydroxide [$Al(OH)_{3}$] is a basic inorganic compound used to manage gastric distress.

Step 2: Meaning
An antacid is a substance that neutralizes stomach acidity.

Step 3: Analysis
Aluminium hydroxide reacts with the excess hydrochloric acid in the stomach to form aluminium chloride and water, thereby reducing acidity without significantly affecting systemic pH.
