Analysis of drug-induced posterior reversible encephalopathy syndrome using the food and drug administration adverse drug events reporting system database.

Our results show that the drugs most commonly suspected to cause PRES were antineoplastics, immunosuppressants, and glucocorticoids. Future studies are needed to illuminate the pathophysiological alterations that underlie PRES. In the meantime, prescribers and patients should be made aware of the potential risks of PRES associated with pharmaceutical therapy, and the summaries of product characteristics for individual drugs should be updated to include this information.
