Proton pump inhibitor (PPI) failure is very common and may affect up to one-third of the PPI consumers. Identifying the underlying mechanisms for PPI failure in each individual patient is essential for treatment success. For residual acid reflux, increasing the PPI dose to twice daily; switching to another PPI, or adding an histamine 2 receptor antagonist could be a successful therapeutic strategy. In patients with duodenogastroesophageal reflux, weak acidic/alkaline reflux and hypersensitivity to acid reflux, therapeutic modalities that reduce transient lower esophageal sphincter relaxation or visceral pain could be entertained. Treatment of PPI failure due to delayed gastric emptying should be focused on improving gastric motor activity. Psychological management may supplement any medical or surgical approach toward PPI failure.
