WebThe advent of combination antiretroviral therapy has led to significant improvement in the care of HIV-infected patients. Originally designed as a protease inhibitor (PI), ritonavir is currently exclusively used as a pharmacokinetic enhancer of other protease inhibitors, predominantly due to ritonavir's potent inhibition of the cytochrome P450 3A4 isoenzyme.

WebJan 3, 2016 · PROTEASE INHIBITORS • They bind reversibly to active sites of HIV aspartic protease enzyme and interfere with its cleaving function. • Because they act at a late step of viral cycle, they are effective against both newly and chronically infected cells. • Hence HIV produce noninfectious viral progeny. 4. WebPatterns of protease covariation were dominated by the clustering of nelfinavir-associated mutations (D30N and N88D), two main groups of protease inhibitor (PI)-resistance mutations associated either with V82A or L90M, and a tight cluster of mutations associated with decreased susceptibility to amprenavir and the most recently approved PI …

WebBecause they are cheaper and easier to produce than protease inhibitors, they helped scale up antiretroviral therapy in resource-limited settings. Identification of novel drug targets has played a key role in discovery and development of new antiretroviral drug classes.
