Displaying 3 results of Baricitinib Stable Isotopes Baricitinib stable isotopes are non-radioactive forms of the drug baricitinib, which is commonly used to treat rheumatoid arthritis. These isotopes are used in research studies to investigate the pharmacokinetics and pharmacodynamics of baricitinib. They are chemically identical to the natural form of the drug, but their atomic structure has been modified to include stable isotopes of certain elements such as carbon, nitrogen or hydrogen. This modification allows for precise tracking and quantification of the drug's movement within the body, which can help in the development of more effective treatments for rheumatoid arthritis.
