Maraviroc is an antiretroviral medication that acts as a CCR5 antagonist, used in combination therapy for the treatment of HIV-1 infection. It prevents viral entry into host cells by blocking the CCR5 co-receptor. Maraviroc is approved and currently in clinical use for HIV therapy.
Pharmacokinetics
Pharmacokinetic parameters in healthy adult volunteers after single oral administration.
