Core Tip

Core tip: Proton pump inhibitors (PPIs) have been widely used in patients with liver disease. In general, PPIs are considered safe. However, accumulating evidence indicates that long-term and excessive use of PPIs without clear indication can lead to serious adverse reactions. Some epidemiological studies have investigated the association of PPI use with the risk of hepatic encephalopathy. However, the results are controversial. The study reveals that PPI use increases hepatic encephalopathy risk in patients with liver disease. This reminds clinicians to be more cautious when using PPIs in patients with liver disease.
