Displaying 4 results of Levothyroxine Stable Isotopes Levothyroxine Stable Isotopes are isotopes of the hormone levothyroxine that have a stable atomic mass. These isotopes are used in medical research to study the metabolism and pharmacokinetics of the hormone in the body. They also play a crucial role in the development of new therapies for thyroid disorders by helping researchers understand the biological mechanisms of the hormone. The use of stable isotopes in research allows for precise and accurate measurements of the hormone's effects, leading to more effective treatments for patients.
