Esomeprazole, sold under the brand name Nexium [or Neksium] among others,[2] is a medication which reduces stomach acid.[11] It is used to treat gastroesophageal reflux disease, peptic ulcer disease, and Zollinger–Ellison syndrome.[11][12] Its effectiveness is similar to that of other proton pump inhibitors (PPIs).[13] It is taken by mouth or injection into a vein.[11]

Common side effects include headache, constipation, dry mouth, and abdominal pain.[11] Serious side effects may include angioedema, Clostridioides difficile infection, and pneumonia.[11] Use in pregnancy appears to be safe, while safety during breastfeeding is unclear.[3] Esomeprazole is the (S)-(−)-enantiomer (or less specifically the S-isomer) of omeprazole.[11] It works by blocking H+/K+-ATPase in the parietal cells of the stomach.[11]

It was patented in 1993 and approved for medical use in 2000.[14] It is available as a generic medication and sold over the counter in several countries.[15][12] In 2022, it was the 122nd most commonly prescribed medication in the United States, with more than 5 million prescriptions.[16][17] In Australia, it was one of the top 10 most prescribed medications between 2017 and 2023.[18] It is also available in lower dose formulations without a prescription in the United States,[19] the United Kingdom[20] as well as Australia, Canada, and New Zealand.[21]
