Ritonavir (ABT-538; Norvir)

Description: Ritonavir (previously known as ABT-538; A-84538; RTV; ABT538, trade name: Norvir) is a L-valine derivative and potent inhibitor of HIV-1 protease used to treat HIV infection and AIDS. It is widely used as a booster for other protease inhibitors/PIs such as lopinavir, and makes them work better. More specifically, ritonavir is used to inhibit a particular liver enzyme that normally metabolizes protease inhibitors, CYP3A4. Ritonavir exhibits potent in vitro inhibition against HIV-1 strain as well as HIV-2 strain with 50% effective concentration EC50 values of 0.022 uM and 0.16 uM respectively.
