Application

Ritonavir has been used:
  • as a human immunodeficiency virus (HIV) protease inhibitor to study its effects on placental endocrine function
  • as an HIV protease inhibitor to study its effects on reduction of tetrazolium dye in human embryonic kidney cells
  • as an organic anion transporting polypeptide (OATP) inhibitor to study its effect on hepatic uptake of bergapten and imperatorin

Biochem/physiol Actions

Ritonavir is an HIV protease inhibitor now used frequently as a booster of other protease inhbitors. Ritonavir inhibits cytochrome P450-3A4 (CYP3A4), a liver enzyme that normally metabolizes protease inhibitors. It has also been investigated as a possible anti-cancer agent.
