Protease inhibitors (PIs) are synthetic drugs that interrupt the action of the HIV enzyme protease PIs bind the active site on the HIV enzyme known as protease. Protease cleaves the long inactive protein strands produced during viral protein synthesis into active viral component proteins. Protease inhibitors bind to the active site of the protease enzyme and prevent the maturation of the newly produced virions so that they remain non-infectious.
Drugs in this class are associated with metabolic abnormalities including dyslipidemia, hyperglycemia, insulin resistance, lipodystrophy, etc.
