Answer

Antiretroviral agent, CCR5 antagonist

These agents block viral entry into white blood cells via the CCR5 co-receptor.

Maraviroc (Selzentry)

Maraviroc blocks viral entry via the CCR5 co-receptor into WBCs, reduces viral load, and increases T-cell counts in infection with CCR5-tropic HIV-1 (ie, R5 virus). Accelerated approval by the US Food and Drug Administration (FDA) was based on 24-wk data. This agent is indicated for combination treatment with optimized background therapy in treatment-experienced adults infected with only R5 virus who have evidence of viral replication and have HIV-1 strains resistant to multiple antiretroviral agents.
