adrenergic response definition
Adrenergic drugs. Definition. Adrenergic amines are drugs that stimulate the sympathetic nervous system (also called the adrenergic nervous system). These compounds are also called sympathomimetic drugs. Adrenergic drugs have many uses. They are used to increase the output of the heart, to raise blood pressure, and to increase urine flow as part of the treatment of shock. Adrenergics are also used as heart stimulants.

Any of several reactive components of effector tissues most of which are innervated by adrenergic postganglionic fibers of the sympathetic nervous system and are activated by norepinephrine, epinephrine, and various adrenergic drugs. Adrenergic agonist. An adrenergic agonist is a drug that stimulates a response from the adrenergic receptors. The five main categories of adrenergic receptors are: α1, α2, β1, β2, and β3, although there are more subtypes, and agonists vary in specificity between these receptors, and may be classified respectively. Medical Definition of Beta adrenergic blocking agents. Beta adrenergic blocking agents: A class of drugs, also called beta blockers, that block beta-adrenergic substances such as adrenaline (epinephrine), a key agent in the sympathetic portion of the autonomic (involuntary) nervous system. By blocking the action of the sympathetic nervous system on the heart, these agents relieve stress on the heart. adrenergic (ad´rinur´jik), adj 1. transmitted by norepinephrine or activated by norepinephrine or the other sympathomimetic agents. n 2. a term applied to nerve fibers that liberate epinephrine or norepinephrine at a synapse when a nerve impulse passes. n 3. a drug that mimics the action of adrenergic nerves. n.pl drugs that mimic the actions of norepinephrine, a neurotransmitter, resulting in stimulation of the sympathetic nervous system. adrenergic. 1  1. Relating to a neuron that is activated or capable of releasing adrenaline (epinephrine). 2  3. Relating to drugs that mimic the effects of the sympathetic nervous system (sympathomimetic drugs). adrenergic receptor. adrenergic receptor n. Any of several reactive components of effector tissues most of which are innervated by adrenergic postganglionic fibers of the sympathetic nervous system and are activated by norepinephrine, epinephrine, and various adrenergic drugs. adrenergic receptors.
