| How do angiotensin receptor antagonists work? | They block the binding of angiotensin to it's receptor |
| How do calcium channel blockers work? | Block the entry of calcium into the cell. (Smooth muscle tone is controlled by cystolic calcium) |
| How do alpha1- adrenoreceptor antagonists work? | Block cystolic calcium from entering the cell and selectively block vascualar alpha1 receptors |
