Ritonavir: a Booster of Other Protease Inhibitors

Ritonavir was originally developed as an inhibitor of HIV protease inhibitor (PI). Ritonavir is currently exclusively used as a pharmacokinetic enhancer (booster) of other protease inhibitors, due to ritonavir's potent inhibition of the cytochrome P 450 3A4 (CYP3A4), an enzyme that is responsible for metabolizing most HIV PIs.
