Displaying 2 results of Ethionamide Stable Isotopes Ethionamide stable isotopes are non-radioactive forms of ethionamide, a medication used in the treatment of tuberculosis. These isotopes are commonly used in drug metabolism studies, pharmacokinetic research, and other medical applications. By incorporating stable isotopes into ethionamide, researchers can track the drug's movement through the body and better understand its effects and interactions with other substances. These isotopes offer a safe and effective way to study the pharmacology of ethionamide without the risks associated with radioactive isotopes.
