Displaying 5 results of Erdosteine Stable Isotopes Erdosteine is a thiol-containing mucolytic agent that is used in the treatment of respiratory disorders. Stable isotopes of erdosteine are non-radioactive isotopes that have the same number of protons but different numbers of neutrons compared to the naturally occurring isotopes. These isotopes are used in research and clinical studies to study the pharmacokinetics and metabolism of erdosteine. They are also used in the development of new drugs and therapeutic applications of erdosteine.
