Integrase inhibitor

Integrase inhibitors are a class of antiretroviral drug developed for the treatment of HIV infection. They block the action of integrase, an enzyme that integrates genetic material from the virus into its target cell. No integrase inhibitors have yet received governmental approval, although two are currently undergoing testing.
