Northwestern is doing a trial right now (it may have concluded, not sure) on calcium, not potassium, channel blockers. Wonder why they are not doing it on potassium channel blockers, given their prior research? It is for this reason that we are taking Dynacirc, which is a calcium channel blocker- typically scripted for high blood pressure, which we dont' have. We have to watch the BP to be sure it doesn't drop too low, and so far it hasn't (makes one wonder if this drug works for the high BP) and we are watching for the results from Northwestern on this trial.
