Oxybutynin-d11 chloride（Cat No.:R006900）is a deuterium-labeled form of oxybutynin, containing eleven deuterium atoms for enhanced stability and precise detection in mass spectrometry. It is used in pharmacokinetic and metabolic studies to assess drug absorption, distribution, and elimination. Oxybutynin-d11 chloride retains the anticholinergic and antispasmodic activity of the parent compound, acting as a muscarinic receptor antagonist to relax bladder smooth muscle and reduce urinary urgency in overactive bladder disorders. Its stable isotope labeling allows for accurate differentiation from endogenous and administered oxybutynin, making it essential for bioanalytical assays and drug interaction research.
