Enfuvirtide: a new class of antiretroviral therapy for HIV infection

Abstract
Enfuvirtide is the first of a new class of antiretroviral agents recently approved for the treatment of human immunodeficiency virus (HIV)-1 infection. Present available data suggest that enfuvirtide may be a promising agent for the control of HIV infection in patients who have previously received reverse transcriptase inhibitor and protease inhibitor regimens and who are either intolerant to such drugs and/or who have gone into virological failure. Perhaps the greater limitation to the clinical use of enfuvirtide is the cost, limiting its use in the developing world.
