Displaying 2 results of Carbocisteine Stable Isotopes Carbocisteine stable isotopes are non-radioactive forms of the chemical compound carbocisteine, which is commonly used as a mucolytic agent and expectorant in respiratory diseases. The stable isotopes of carbocisteine are used in research and clinical studies to track the metabolic fate of the drug in the body and to investigate its pharmacokinetics and pharmacodynamics. These isotopes are also used in the development of new and more efficient formulations of carbocisteine for the treatment of respiratory disorders.
