That liver enzyme chart answered my question about other calcium channel blockers being problematic also...YES, it appears so.

MrsD. Don't know if you can explain this in a way I can understand, but isn't the domperidone using the same pathway as the Cardizem? Quote from Drug.com: "the main metabolic pathway of domperidone is through CYP3A4"

If so, how does this work in conjunction with a medicine like Cardizem? Can they actually share the same pathway without a problem? I notice Domperidone lists some of the interactor meds as inhibitors (Macrolide antibiotics), but not any of the calcium channel blockers...so does that means they are sharing the pathway without reaction?

In other words, just because they share the same path, does it always mean there will be a problem?
