PPI — Proton Pump Inhibitors
What PPI means
PPIs irreversibly block the gastric hydrogen–potassium ATPase pump, producing profound and sustained suppression of stomach acid. Omeprazole, pantoprazole, and esomeprazole are common examples. They are the most effective drugs for healing reflux esophagitis and peptic ulcers.
PPI in clinical practice
Exam favorites include timing — taking PPIs thirty to sixty minutes before meals maximizes effect — plus key associations such as Clostridioides difficile risk with prolonged use. The ClinIQ GERD article positions PPIs within the reflux treatment ladder and their evidence-backed duration.
