It is a logical conclusion that blocking the ACE-2 receptor, as ARBs are wont to do, should offer some protection against the virus by inhibiting it’s site of attachment. Now, logical conclusions that should be true are deadly errors in medicine. I would absolutely not recommend starting an ARB for this purpose, nor depending on your BP meds for protection if you are already on one. That said, should this pan out in actual studies, it would be an intriguing target for further manipulation. Add chloroquine as a potential treatment and we have some possible weapons already in hand. If only they will work in practice.
