What Is Adrenergic?
Adrenergic is a term used to describe proteins and drugs that interact with adrenaline or noradrenaline, also known as epinephrine and norepinephrine, respectively. For example, adrenergic receptors are membrane proteins that are the target for epinephrine and norepinephrine, while adrenergic transporters are proteins that carry norepinephrine across the cell membrane of nerve cells. An adrenergic agonist is a drug that typically produces the same effect as epinephrine or norepinephrine, where as an adrenergic antagonist is a drug that generally blocks the effects of epinephrine and norepinephrine. Epinephrine and norepinephrine act as hormones and neurotransmitters in numerous biological processes.
