Displaying 3 results of Nizatidine Stable Isotopes Nizatidine stable isotopes are non-radioactive isotopes of the medication nizatidine. They are used in research and development to study the pharmacokinetics and metabolism of the drug in the body. These isotopes are chemically identical to the naturally occurring isotopes of nizatidine, but have a different number of neutrons in the nucleus. They are safe and effective tools for investigating the effects of nizatidine on biological systems.
