From the Research

Association between Prilosec (Omeprazole) and Gastrointestinal Stromal Tumors (GIST)

  • There is no direct evidence in the provided studies to suggest a link between the chronic use of Prilosec (Omeprazole) and the development of Gastrointestinal Stromal Tumors (GIST) 1, 2, 3, 4, 5.
  • The studies primarily focus on the pharmacology, pharmacokinetics, and effects of omeprazole on gastric acid secretion and its use in treating conditions like duodenal ulcers and reflux oesophagitis.
  • None of the studies mention GIST or investigate the long-term effects of omeprazole on the development of such tumors.
  • Therefore, based on the provided evidence, there are no research papers to assist in answering this question regarding the association between chronic omeprazole use and GIST development.
