(S)-Fesoterodine-d7 Fumarate is a deuterated form of (S)-fesoterodine, a selective muscarinic receptor antagonist used to treat overactive bladder by reducing urinary frequency and urgency. The seven deuterium atoms replace hydrogen atoms in the molecule, providing a stable isotopic label that enhances precision in pharmacokinetic and metabolic studies. This labeled compound is useful for accurately tracking the drug’s absorption, distribution, metabolism, and excretion in clinical research. Its applications are crucial in optimizing dosing regimens, studying drug interactions, and improving therapeutic strategies for managing overactive bladder syndrome.
