Attachment Inhibitor

Attachment inhibitors are a class of drugs that bind to the gp120 protein on the outer surface of HIV, preventing HIV from binding to and entering CD4 T lymphocytes (CD4 cells). Attachment inhibitors are part of a larger class of HIV drugs called entry inhibitors. Currently, attachment inhibitors are still under investigation and have not been approved by the Food and Drug Administration (FDA) for patient use.
