Displaying 6 results of Nintedanib Stable Isotopes Nintedanib is a small molecule drug used in the treatment of idiopathic pulmonary fibrosis (IPF), non-small cell lung cancer (NSCLC), and other fibrotic diseases. Stable isotopes of Nintedanib are used in research studies to track the drug's metabolism and distribution in the body. These isotopes, which are chemically identical to the naturally occurring form of the drug, allow for precise and accurate measurements of drug levels in biological samples. This information can help researchers better understand how the drug works and how it can be optimized for therapeutic use.
