Displaying 3 results of Dextromethorphan Stable Isotopes Dextromethorphan is a synthetic opioid drug that is commonly used as a cough suppressant. Dextromethorphan stable isotopes are isotopically labeled versions of the drug that are used in pharmacokinetic studies and drug metabolism research. They are chemically identical to the natural compound but contain specific isotopes that allow for precise measurement and tracking of the drug's movement in the body. These stable isotopes are essential tools in drug development and can provide valuable insights into the safety and efficacy of dextromethorphan and other drugs.
