Afatinib is a medication used in the treatment of non-small cell lung cancer. Afatinib Stable Isotopes are isotopically labeled versions of the drug that are used in pharmacokinetic and pharmacodynamic studies. These isotopes are chemically identical to the original drug, but contain a stable isotope that can be tracked and measured in biological samples. This allows researchers to study the drug's behavior in the body and its effects on cancer cells with greater precision.
