If it's a safer beta blocker it would make a good candidate for higher-risk hypertension patients (diabetes, obesity, CHF, COPD) and that's what FRX is trying to prove in many ongoing phase IV trials for Bystolic.
>I wonder why anyone is still taking a beta blocker for lowering BP.<
For some people (like my father), antagonizing the angiotensin pathway (ACEi, ARB) doesn't work. For those people, beta-blockers aren't a bad option because they reduce cardiac output.
