Question 1
Combivir is a combination therapy used to treat HIV and AIDS include which * of the following drugs?
- A. Lamivudine and stavudine
- B. Lamivudine and zidovudine
- C. Abacavir and zidovudine
- D. Abacavir and stavudine
Show answer and rationale
Correct answer: B — Lamivudine and zidovudine
The correct answer is B: Lamivudine and zidovudine. Combivir is a combination therapy that consists of these two drugs. Lamivudine and zidovudine work together to inhibit the replication of the HIV virus. Lamivudine is a nucleoside reverse transcriptase inhibitor, while zidovudine is a nucleoside analog reverse transcriptase inhibitor. Both drugs target different stages of the HIV life cycle, making them effective when used in combination. Choice A (Lamivudine and stavudine) is incorrect because stavudine is not part of the Combivir combination therapy. Choice C (Abacavir and zidovudine) is incorrect because abacavir is not included in Combivir. Choice D (Abacavir and stavudine) is incorrect because stavudine is not part of the Combivir combination therapy.
