Displaying 2 results of Dicyclomine Stable Isotopes Dicyclomine is a medication used to treat irritable bowel syndrome and other gastrointestinal conditions. Stable isotopes of dicyclomine are non-radioactive isotopes that have the same number of protons and electrons as the naturally occurring element, but a different number of neutrons. These isotopes can be used in research and drug development to study the pharmacokinetics and metabolism of dicyclomine, as well as to track the drug in biological samples.
