Metamizole-d₃ sodium  (Synonyms: Dipyrone-d₃)

Metamizole-d3 sodium is the deuterium labeled Metamizole sodium. Metamizole sodium is a non-opioid compound with excellent analgesic and antipyretic effects. Metamizole sodium is a cyclooxygenase-3 (COX-3) inhibitor^[1][2].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
