What is the mechanism of action of Maraviroc?

• A. It inhibits reverse transcriptase
• B. It acts as a CCR5 antagonist
• C. It blocks viral protease activity
• D. It enhances viral RNA synthesis

Answer: (B)

Maraviroc functions as a CCR5 antagonist, which is integral to its mechanism of action in treating HIV infections. CCR5 is a co-receptor found on the surface of certain immune cells, which the HIV virus uses to enter these cells. By binding to the CCR5 receptor, Maraviroc prevents HIV from attaching and entering the host cells, effectively inhibiting the virus's ability to replicate and cause infection. This specific targeting of the CCR5 receptor highlights the strategic approach that Maraviroc takes to disrupt the life cycle of the virus, differentiating it from other antiviral agents that may work by inhibiting viral enzymes or processes, such as reverse transcriptase or protease inhibitors. Understanding this mechanism is crucial for comprehending how different antiviral therapies can be utilized in a combinational strategy to effectively manage HIV treatment.
