Displaying 4 results of Finasteride Stable Isotopes Finasteride Stable Isotopes refer to isotopically labeled versions of the drug finasteride, which is commonly used to treat hair loss in men. Stable isotopes are non-radioactive isotopes of elements that have the same number of protons but different numbers of neutrons. These labeled versions of finasteride are used in research and development to help understand the drug's mechanism of action and its pharmacokinetics in the body. By incorporating stable isotopes into the drug molecule, researchers can track and measure the drug's movement and metabolism in the body, providing valuable insights into its efficacy and safety.
