Displaying 2 results of Cefotaxime Sodium Stable Isotopes Cefotaxime Sodium Stable Isotopes are non-radioactive isotopes of the antibiotic drug cefotaxime sodium. These isotopes have the same chemical properties as the naturally occurring isotopes but have a different number of neutrons in the nucleus. They are used in pharmacokinetic studies to determine the absorption, distribution, metabolism, and excretion of cefotaxime sodium in the body. These stable isotopes offer a safe and effective alternative to radioactive isotopes in research and diagnostic applications.
