What is the role of maraviroc in HIV management?

• A. It is a non-nucleoside reverse transcriptase inhibitor.
• B. It is a CCR5 antagonist.
• C. It is a nucleoside reverse transcriptase inhibitor.
• D. It is a protease inhibitor.

Answer: (B)

Maraviroc plays a distinct role in HIV management as a CCR5 antagonist. This means that it specifically targets and binds to the CCR5 co-receptor on the surface of certain immune cells, which is one of the pathways that HIV uses to enter these cells. By blocking this co-receptor, maraviroc effectively prevents CCR5-tropic strains of HIV from infecting the cells, thereby impeding viral replication. This targeting mechanism helps to reduce the viral load in individuals infected with CCR5-utilizing strains, leading to better management of HIV. Since maraviroc is not a nucleoside or non-nucleoside reverse transcriptase inhibitor and also does not function as a protease inhibitor, it performs a unique and critical function that complements other classes of antiretroviral drugs used in HIV treatment regimens. Understanding the role of maraviroc aids in the development of effective combination therapies for HIV management.
