Displaying 8 results of Terbutaline Stable Isotopes Terbutaline stable isotopes are non-radioactive forms of the drug terbutaline, which is commonly used to treat asthma and other respiratory conditions. These isotopes are chemically identical to the regular form of terbutaline, but they have a different number of neutrons in their atomic nuclei, making them useful in scientific research. By using these stable isotopes, researchers can track the distribution and metabolism of terbutaline in the body, which can help improve our understanding of how the drug works and how it can be used more effectively.
