Displaying 3 results of Tezacaftor Stable Isotopes Tezacaftor is a novel drug used to treat cystic fibrosis. It works by improving the function of a protein called cystic fibrosis transmembrane conductance regulator (CFTR). Tezacaftor stable isotopes are labeled versions of the drug that are used in research studies to track its metabolism and distribution in the body. These isotopes are essential tools for understanding the pharmacokinetics and pharmacodynamics of Tezacaftor, which can inform the development of more effective treatments for cystic fibrosis.
