The main active component of this medicine is Efavirenz, which is a synthetic non-nucleoside reverse transcriptase inhibitor with antiviral activity. It helps binds directly to the human immunodeficiency virus type 1 (HIV-1) RT, an RNA-dependent DNA polymerase, blocking its function in viral DNA replication. It has been shown to significantly reduce HIV viral load, retarding or preventing damage to the immune system and reducing the risk of developing AIDS. It induces the activity of the cytochrome P450 system, accelerating its metabolism.
