What is a PI based regimen?
PI-based regimens using pharmacokinetic (PK) enhancement with either cobicistat (COBI) or RTV (also called PK boosting) increase concentration and prolong the half-lives of the PI. These regimens have demonstrated virologic potency, durability in treatment-naive patients, and a high barrier to resistance.

Which drug is a protease inhibitor?
