Displaying 2 results of Naratriptan Stable Isotopes Naratriptan Stable Isotopes are a set of stable isotopes of the drug naratriptan. These isotopes have the same chemical and physical properties as the non-radioactive form of naratriptan but have a different number of neutrons in their nucleus. These isotopes are used in research and drug development to study the pharmacokinetics and metabolism of naratriptan. They are also used in drug discovery to identify new targets for the treatment of migraine headaches.
