Displaying 5 results of Tiagabine Stable Isotopes Tiagabine Stable Isotopes are non-radioactive forms of the medication tiagabine that are used in research and development. These isotopes have the same chemical and physical properties as regular tiagabine, but they contain stable isotopes of carbon, hydrogen, nitrogen, and chlorine. Tiagabine Stable Isotopes are useful in drug metabolism studies, pharmacokinetics, and drug interaction studies. They are also used in the development of analytical methods for tiagabine quantification in biological matrices.
