What do alpha 2 adrenergic blockers do?
The precise mechanism of action of alpha 2 adrenoceptor blockers in not known, although in principle they have two main effects: (i) they stimulate the norepinephrinergic system by inhibiting the negative feed back of norepinephrine release (presynaptic effect) and (ii) they inhibit the effects of norepinephrine on …
What are the general effects of adrenergic blockers?

These alpha blockers widen the blood vessels by blocking both alpha 1 and alpha 2 receptors. The blocking of alpha 1 receptors causes the widening of the blood vessels by inhibiting the action of catecholamines that cause vasoconstriction. The blocking of alpha 2 receptors increases the release of norepinephrine.
