- Stops entry of virus resistant to other classes
- Acts before co-receptor binding — the earliest step in the entry sequence
Drugs with this mechanism (1)
- Temsavir — Active fostemsavir metabolite that binds HIV gp120 and blocks attachment; used in regimens for heavily treatment-experienced patients.
