Omeprazole stable isotopes are non-radioactive isotopes of omeprazole that are used in research and clinical applications. These isotopes are chemically identical to regular omeprazole, but have a different number of neutrons in their atomic nuclei. They are useful in studies of drug metabolism and pharmacokinetics, as well as in the development of new diagnostic tools and therapies. Omeprazole stable isotopes are also used in tracer studies to investigate the effects of omeprazole on the body.
