Understanding Antacids

The video tutorial explains what antacids are and how they work to neutralize excess stomach acid, alleviate discomfort, and prevent damage to the stomach lining. It covers the mechanisms of action of two common antacids: aluminium hydroxide and calcium salts. Aluminium hydroxide neutralizes stomach acid and inhibits pepsin, while calcium salts also neutralize acid and release gas to aid digestion.

What is the primary reason for using antacids?

• To neutralize excess stomach acid

• To decrease stomach size

• To increase stomach acid

• To promote acid production

Which of the following is NOT a function of antacids?

• Increasing stomach acid production

• Alleviating pain and discomfort

• Neutralizing stomach acids

• Preventing corrosion of the stomach lining

What is the main component of the first commonly used antacid discussed?

• Calcium carbonate

• Sodium bicarbonate

• Magnesium hydroxide

• Aluminium hydroxide

How does aluminium hydroxide primarily work as an antacid?

• By increasing stomach acid

• By forming a harmful salt

• By neutralizing HCl to form a harmless salt and water

• By decreasing peristalsis

What is a key effect of calcium salts as an antacid?

• They decrease the pH to less than 4

• They release gas to increase esophageal sphincter tone

• They inhibit the production of stomach acid

• They cause stomach lining corrosion

What is the role of the gas released by calcium salts?

• To neutralize pepsin

• To increase lower esophageal sphincter tone

• To decrease peristalsis

• To decrease stomach acid

Which antacid helps in bringing the pH to greater than 4?

• Sodium bicarbonate

• Magnesium hydroxide

• Calcium salts

• Aluminium hydroxide

What is the effect of antacids on peristalsis?

• They stop peristalsis

• They increase peristalsis

• They have no effect on peristalsis

• They decrease peristalsis

What is the purpose of the video tutorial?

• To discuss the side effects of antacids

• To help understand how antacids work

• To promote a specific brand of antacids

• To explain the history of antacids
