The theory with ACE inhibitors (ARB, Angiotensin Receptor Blockers) has flipped since January. Since the SARS-CoV-2 binds to the ACE-2 receptor, the first theory to come out (and be minimally data-tested) was that these drugs may help stop infection because they block the site where the virus binds. But, as it turns out, witg a little more data drudging, they probably make things worse.
This might be bad data dredging; because if hypertension is a serious independent risk factor, it makes isolating the ARB very hard to separate out as a confounder without controlled, experiments.
Now the thinking is that because the ARB therapy likely causes uptake of these receptors in response to therapy (that people who take them actually have more ACE-2 receptors on the surface of their cells) that the virus has more targets to bind.
Therefore, if true, ARB therapies make people who may already be more likely to contract serious illness easier to infect. Like shooting fish in a barrel (in a small barrel with a lot of fish and a shotgun).
