Abstract

Treatment of HIV infection has typically been carried out using two nucleoside analogs and a protease inhibitor. Such regimens can be complex and have high pill burdens. Use of alternative regimens, such as triple nucleoside-based regimens, can improve adherence and decrease toxicities associated with protease inhibitor therapy. A formulation of abacavir sulfate/lamivudine/zidovudine allows a dosing schedule of one pill twice daily. The components have performed favorably compared with protease inhibitor-based regimens, such as indinavir. Compared with efavirenz-based regimens, abacavir sulfate/lamivudine/zidovudine has not performed as well. The combination is being studied as a cornerstone for induction maintenance strategies, in which switching a patient to abacavir sulfate/lamivudine/zidovudine has been associated with similar virologic outcomes as continuing with either protease inhibitor- or efavirenz-based regimens. Administration of abacavir sulfate/lamivudine/ zidovudine also avoids side effects of antiretroviral therapy, such as hyperlipidemia, but its use is associated with a hypersensitivity reaction in a small number of patients. The combination of abacavir sulfate/lamivudine/zidovudine is an important part of the HIV armamentarium. Its potency and ease of administration make it worth consideration in the treatment of HIV, either by itself or in combination with other agents.
