Post-Attachment Inhibitor

Post-attachment inhibitors are a class of drugs that block HIV from binding to the CCR5 and CXCR4 coreceptors after HIV binds to the CD4 receptor on the surface of a CD4 cell. This prevents HIV from entering the cell. Post-attachment inhibitors are part of a larger group of HIV drugs called entry inhibitors.
