Options

A. Neutralize the excess of acid in the stomach
B. Prevent the formation of acid in the stomach
C. Formation of acid in the stomach
D. Causes ulcers in the stomach

Answer

### Step-by-Step Text Solution:

1. **Understanding Lansoprazole**: Lansoprazole is a medication classified as a proton pump inhibitor (PPI). It is primarily used to reduce the amount of acid produced in the stomach.

2. **Mechanism of Action**: The main action of Lansoprazole is to inhibit the proton pumps in the stomach lining. These proton pumps are responsible for the secretion of hydrogen ions (H+), which combine with chloride ions to form hydrochloric acid (HCl), the main component of stomach acid.

3. **Effect on Stomach Acid**: By inhibiting these proton pumps, Lansoprazole effectively reduces the production of stomach acid. This action helps in treating conditions associated with excessive stomach acid, such as gastroesophageal reflux disease (GERD) and peptic ulcers.

4. **Treatment of Esophagus Problems**: Lansoprazole is also used to treat certain esophageal problems. The esophagus is the tube that connects the throat to the stomach, and issues like inflammation or damage can occur due to acid reflux. By reducing stomach acid, Lansoprazole helps alleviate these problems.

5. **Side Effects**: While Lansoprazole is effective in treating acid-related conditions, it may have side effects, including but not limited to sunburns and cough.

6. **Conclusion**: In summary, Lansoprazole acts as an anti-acid by preventing the formation of excess stomach acid and treating related esophageal issues.
