Which drug combination contains both Abacavir and Lamivudine?

The correct answer is the combination that contains both Abacavir and Lamivudine. In this case, Epzicom is a fixed-dose combination medication that comprises both of these drugs. Abacavir is an NRTI (nucleoside reverse transcriptase inhibitor) and is used in the treatment of HIV, while Lamivudine is also an NRTI with a similar function in battling the virus. The formulation is specifically designed for easier adherence to therapy by combining two effective antiretrovirals into one pill.

In other formulations listed, Triumeq includes an additional active ingredient, Dolutegravir, alongside Abacavir and Lamivudine, which gives it a different therapeutic profile. Trizivir also combines Abacavir and Lamivudine but includes Zidovudine, which differentiates it from Epzicom. Finally, Combivir comprises Lamivudine and Zidovudine but does not contain Abacavir. Therefore, Epzicom stands out as the specific drug combination solely featuring both Abacavir and Lamivudine.
