Lansoprazole is not used in which of the following cases?

Question

Options

• AGastritis
• BPeptic Ulcers
• CZollinger-Ellison syndrome
• DThalamus hypertrophy

• A
  11% (3)
• B
  4% (1)
• C
  7% (2)
• D
  78% (21)

Explanation

Option D is correct because "thalamus hypertrophy" is not a recognized medical indication for lansoprazole - the thalamus is a brain structure, entirely unrelated to the gastrointestinal tract where lansoprazole acts. No PPI (proton pump inhibitor) is used for any neurological condition.

Why the other options are wrong (i.e., lansoprazole IS used for them):

• A. Gastritis - Lansoprazole reduces gastric acid secretion, relieving mucosal inflammation and allowing healing.
• B. Peptic Ulcers - PPIs are first-line treatment for peptic ulcers, often combined with antibiotics for H. pylori eradication.
• C. Zollinger-Ellison Syndrome - This condition causes excessive acid hypersecretion due to a gastrinoma; high-dose PPIs like lansoprazole are the cornerstone of management.

Memory tip: Remember lansoprazole's scope with "GUT, not BRAIN" - all its indications (GERD, ulcers, gastritis, Zollinger-Ellison) are gastrointestinal. Any option referencing a CNS or neurological structure is automatically out of scope for any PPI.
