Which two antiretroviral drugs are combined in Epzicom?

The correct answer is based on the fact that Epzicom is a fixed-dose combination tablet that specifically includes two antiretroviral drugs: abacavir and lamivudine. These drugs are nucleoside reverse transcriptase inhibitors (NRTIs) that work synergistically to inhibit viral replication in individuals infected with the human immunodeficiency virus (HIV).

Abacavir is notable for its use in patients who may have a specific genetic variant that impacts their reaction to the drug, while lamivudine is widely used due to its favorable safety profile and efficacy. Combining these two medications allows for simplified treatment regimens, improves adherence by reducing pill burden, and enhances overall HIV management.

The other options listed contain different combinations of antiretroviral agents, each used in various treatment regimens for HIV, but none of them combine abacavir and lamivudine as Epzicom does. Understanding this specific combination and its role in HIV treatment is important for effective patient management.
