Integrase inhibitors (INIs) are a class of antiretroviral drug designed to block the action of integrase, a viral enzyme that inserts the viral genome into the DNA of the host cell. Since integration is a vital step in retroviral replication, blocking it can halt further spread of the virus. Integrase inhibitors were initially developed for the treatment of HIV infection but have been applied to other retroviruses. The class of integrase inhibitors called integrase strand transfer inhibitors (INSTIs) are in established medical use. Other classes, such as integrase binding inhibitors (INBIs), are still experimental.
