Displaying 2 results of Methazolamide Stable Isotopes Methazolamide is a medication used to treat glaucoma and other conditions related to increased intraocular pressure. Methazolamide stable isotopes are isotopically labeled versions of the drug, which can be used in research and development to study the pharmacokinetics, metabolism, and efficacy of the drug. These stable isotopes are chemically and biologically identical to the natural form, but contain isotopes of carbon, nitrogen, or hydrogen that are not radioactive and do not decay over time.
