Post-Attachment Inhibitor

Post-attachment inhibitors are a class of drugs that bind to the CD4 receptor on a host CD4 cell. This blocks HIV from attaching to the CCR5 and CXCR4 coreceptors and entering the cell. Post-attachment inhibitors are part of a larger group of HIV drugs called entry inhibitors.
