Adrenergic antagonist

From Wikipedia, the free encyclopedia

An Adrenergic antagonist is a pharmaceutical substance that acts to inhibit the action of the adrenergic receptors. It is thus a type of sympatholytic.

It has the opposite effect as adrenergic agonists.

More specifically, they can be divided into:

• Alpha blockers
• Beta blockers
