Raltegravir

Raltegravir is an integrase strand transfer inhibitor (INSTI) antiretroviral drug. It works by blocking HIV integrase, an enzyme essential for viral replication. This prevents the integration of the viral genetic material into human DNA, effectively reducing the viral load and helping to restore immune system function when used with other HIV medications.
