Pantoprazole-Induced Delirium: Review of a Case andAssociated Literature

Proton pump inhibitors (PPIs) are frequently prescribed antiulcer agents in hospitals and are shown to be safer thanH-2 blockers. We present a case report of PPI-induced delirium, regarding which not much has been written in the literature.CaseReport. We present a case of a 93-year-old woman with no known past psychiatric history, who was hospitalized for syncope workupand who developed delirium after a double dose of pantoprazole.Discussion. Very few reports of PPI-induced delirium exist in theliterature. In this case report, we attempt to highlight the mechanism of PPI induced delirium which in our case was most likelydue to the primary effects of PPI and drug-drug interactions. Given the paucity of literature on this topic, we encourage furtherresearch into relationship between PPI and delirium and urge caution while using PPIs in geriatric population.
