Mechanism of action

Raltegravir is an integrase strand transfer inhibitor (INSTI) that blocks the catalytic activity of HIV integrase, the enzyme responsible for inserting viral DNA into the human genome. By preventing this integration step, the drug blocks HIV replication and reduces viral load in infected individuals. This mechanism is distinct from reverse transcriptase or protease inhibitors and represents a newer class of antiretroviral therapy.
