Displaying 6 results of Entecavir Stable Isotopes Entecavir Stable Isotopes are isotopically labeled forms of the drug Entecavir, which is used to treat chronic hepatitis B virus (HBV) infection. The isotopes can be used in research to study the pharmacokinetics, metabolism, and distribution of Entecavir in the body. They are chemically identical to the non-labeled drug but contain stable isotopes of carbon, nitrogen, and/or hydrogen, which allow for precise tracking of Entecavir in biological systems. These isotopes are commonly used in drug discovery and development, pharmacokinetic studies, and the development of analytical methods for drug quantification.
