Final answer:
Aluminum hydroxide is taken as a medication to control gastric acid secretions in the stomach and relieve symptoms of ulcers, heartburn, or dyspepsia.
Step-by-step explanation:
The purpose of taking aluminum hydroxide is to control gastric acid secretions. Aluminum hydroxide is used as an antacid and helps reduce the acidity of the stomach content, which can relieve symptoms of ulcers, heartburn, or dyspepsia. It reacts with excess acid in the stomach, reducing the pH of the stomach content. Unlike other antacids, aluminum hydroxide does not trigger the secretion of excess stomach acid. However, it may cause constipation as a side effect, as it inhibits the contractions of smooth muscle cells in the gastrointestinal tract.
