Displaying 4 results of Treprostinil Stable Isotopes Treprostinil is a synthetic prostacyclin used for the treatment of pulmonary arterial hypertension. Stable isotopes of treprostinil are used for pharmacokinetic, pharmacodynamic, and metabolic studies. These isotopes are chemically identical to the regular compound but have a different atomic mass, allowing for precise tracking and analysis. These studies help researchers better understand how treprostinil is processed by the body and how it interacts with other drugs.
