Voltage gated channels:

L type (aka dihydropyridine) (mainly in arteries and ventricular muscle - vasodilator/-inotropes) Amlodipine and Nifedipine
T type (mainly in pacemaker and ventricles - class 4 aa's/-inotropes) Verapamil and Diltiazem, also Ethosuximide+Valproate



Ligand gated channels:

Ryanodine (skeletal muscle) Dantrolene



it took me a while to fig this out, maybe it's done before but i just wanted to share a tid-bit

Can you kindly provide a reference?
AFAIK Verapamil & Diltiazem block L-type Ca channels.

Correct me if I'm mistaken. Thanks.
