Proton-pump inhibitors (PPIs) are effective for acid-related diseases but long-term use has potential risks. Most PPI-associated adverse events lack strong evidence, necessitating careful dosing and monitoring.
Area of Science:
- Gastroenterology
- Pharmacology
Background:
- Proton-pump inhibitors (PPIs) are primary treatments for gastric-acid-related conditions.
- Long-term PPI use has been linked to increasing adverse events.
- PPIs induce gastric mucosal changes like polyps and hyperplasia.
Purpose of the Study:
- To review the evidence linking long-term PPI use to adverse events.
- To evaluate the causality of reported PPI-associated complications.
- To guide appropriate PPI therapy and monitoring.
Main Methods:
- Literature review of studies on PPIs and associated risks.
- Analysis of evidence for causal relationships.
- Discussion of confounding factors and mechanisms.
Main Results:
- Most reported associations between PPIs and severe adverse events lack sufficient evidence.
- Confounding factors and lack of plausible mechanisms hinder proof of causality.
- Helicobacter pylori infection may exacerbate PPI-induced changes.
Conclusions:
- Causal relationships for most PPI-associated risks remain unproven.
- Physicians should consider appropriate PPI dosing, duration, and monitoring.
- Patient anxiety should be managed by informed clinical judgment and individualized care plans.

Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
