Displaying 6 results of Dextrorphan Stable Isotopes Dextrorphan stable isotopes are isotopes of the drug dextrorphan that have a stable atomic nucleus and do not decay over time. These isotopes are used in research and medical applications to study the metabolism, pharmacokinetics, and pharmacodynamics of dextrorphan. By labeling dextrorphan with stable isotopes, researchers can track its movement in the body and better understand its effects on various physiological systems. Dextrorphan stable isotopes are also used in the development of new drugs and therapies that target the same or similar pathways as dextrorphan.
