From Wikipedia, the free encyclopedia
An adrenergic is a drug, or other substance, which has effects similar to, or the same as, epinephrine (adrenaline). Alternatively, it may refer to something which is susceptible to epinephrine, or similar substances, such as a biological receptor (specifically, the adrenergic receptors). Beta blockers block the action of epinephrine and norepinephrine in the body. Adrenergic drugs either stimulate a response (agonists) or inhibit a response (antagonists). The five categories of adrenergic receptors are: alpha 1, alpha 2, beta 1, beta 2, and beta 3. Alpha 1 and beta 1 are excitatory, where as alpha 2 and beta 2 are inhibitory.
