Displaying 12 results of Nevirapine Stable Isotopes Nevirapine is a non-nucleoside reverse transcriptase inhibitor used in the treatment of HIV-1 infection. Stable isotopes of nevirapine are isotopically labeled forms of the drug, which have the same chemical and biological properties as the non-labeled compound but contain a specific number of stable isotopes. These isotopes are used in drug metabolism and pharmacokinetic studies to track the fate of the drug in the body, as well as in the development of new analytical methods for the quantification of nevirapine in biological samples.
