CCB vs BB

[LetsChill]

I've noticed that a lot of pts are sometimes on both a calcium channel blocker and a beta blocker P.O. Why is this?

What are the main differences between these two med groups (metoprolol vs cardizem, for example) that would lead a practitioner to prescribe either or?

Is it that CCBs are used more for rate control and BBs are more for BP control?

But then, some ppl take verapamil (CCB) for BP control.

I guess my question is, against what criteria would a practitioner evaluate a pt to receive either or both of these meds?

And I'm not necessarily talking about the MI core measure either. I know those pts always get a BB.
