Question 1

.

What is the single most important reason for proton pump inhibitor failure in gastroesophageal reflux disease?

Helicobacter pylori infection

Rapid metabolism

Poor compliance with inappropriate administration

Delayed gastric emptying

Q1. Correct answer: C


Rationale

There are many potential reasons for PPI failure in patients with symptoms of gastroesophageal reflux. However, the single most important reason is inappropriate drug administration. Patients should be counseled to take their medication 30-60 minutes prior to meals for optimal physiologic gastric acid inhibition, with the morning meal favored over the evening meal due to relative more gastric acid production at this time.
