i know dihydropyridine receptors are found on cardiac and skeletal muscle but are they on smooth muscle? i haven't found an answer but i'm assuming it has to be yes since you have dihydropyridine calcium blockers like nifedipine.

I believe Ca channel blockers prevent extracellular Ca (membrane channels) from entering in the cell, thus it produces an effect on cardiac and smooth muscle, not skeletal.
