Ketoconazole-d₄  (Synonyms: Ketoconazol-d₄; R 41400-d₄)

Ketoconazole-d₄ is the deuterium labeled Ketoconazole. Ketoconazole (R-41400) is an imidazole anti-fungal agent, a CYP3A4 and CYP24A1 inhibitor.

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].
