Stable isotopes of Neratinib are non-radioactive forms of the drug that are used for research purposes. These isotopes have the same chemical and physical properties as the regular drug, but they contain a different number of neutrons in their atomic nuclei. The use of stable isotopes allows researchers to trace the drug's pharmacokinetics and metabolism in the body, as well as to determine its efficacy and safety.
