CAS: 1217720-20-1

Ritonavir-d6 is used as an analytical standard to quantify ritonavir. Ritonavir has an anti-retroviral activity as it inhibits the protease enzymes specific of both HIV-1 and HIV-2. As an added functionality, ritonavir also inactivates significantly the cytochrome P4503A4 (CYP3A4) thus increasing the bioavailability or half-life of other co-administered drugs.
