Generic Sustiva is in a class of drugs called reverse transcriptase inhibitors which also includes zalcitabine (Hivid), zidovudine (Retrovir), didanosine (Videx), and lamivudine (Epivir). During infection with HIV, the HIV virus multiplies within the body's cells. The newly-formed viruses then are released from the cells and spread throughout the body where they infect other cells. In this manner, the infection continually spreads to new, uninfected cells that the body is continually producing, and HIV infection is perpetuated. When producing new viruses, the HIV virus must manufacture new DNA for each virus. Reverse transcriptase is the enzyme that the virus uses to form this new DNA. Generic Sustiva directly inhibits the activity of reverse transcriptase and blocks the production of DNA and new viruses. Unlike zidovudine, efavirenz does not need to be converted to an active form. Generic Sustiva does not kill existing HIV virus and it is not a cure for HIV.
