HIV Protease Inhibitor Ritonavir Induces Cytotoxicity of Human Endothelial Cells

Abstract

These data demonstrate, for the first time, that the HIV protease inhibitor ritonavir at concentrations near clinical plasma levels is able to directly cause endothelial mitochondrial DNA damage and cell death mainly through necrosis pathways but not through apoptosis. This study suggests that HIV protease inhibitor-mediated endothelial injury may contribute to its cardiovascular complications.
