Ritonavir

Ritonavir is an hiv protease inhibitor that works by interfering with the reproductive cycle of hiv. It also inhibits cytochrome p-450 cyp3a. It is a cytochrome p450 3a inhibitor and protease inhibitor. The mechanism of action of ritonavir is as a hiv protease inhibitor, cytochrome p450 3a inhibitor, cytochrome p450 2d6 inhibitor, cytochrome p450 2c19 inducer, cytochrome p450 3a inducer, p-glycoprotein inhibitor, breast cancer resistance protein inhibitor, and cytochrome p450 3a4 inhibitor.
Ritonavir is a peptidomimetic agent that inhibits both hiv-1 and hiv-2 proteases. Ritonavir is highly inhibited by serum proteins but boosts the effect of other hiv proteases by blocking their degradation by cytochrome p450.
