The former synthesizes and releases catecholamines like epinephrine, norepinephrine, and dopamine. The latter produces and releases corticoids and androgens.
A norepinephrine reuptake inhibitor (NRI, NERI) or noradrenaline reuptake inhibitor or adrenergic reuptake inhibitor (ARI), is a type of drug that acts as a reuptake inhibitor for the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline) by blocking the action of the norepinephrine transporter (NET). Some norepinephrine is also synthesized and released into the bloodstream by the adrenal medulla, an endocrine structure that sits above the kidneys. In these circumstances, norepinephrine is signaling as a neurohormonal signal rather than a neurotransmitter. Epinephrine is predominantly produced by specialized cells in the adrenal medulla. Epinephrine and norepinephrine are both acceptable, evidence-based approaches to hemodynamic support in septic shock. Individual patient responsiveness to vasopressors is variable and unpredictable.

Epinephrine Hydrochloride is the hydrochloride salt of the naturally occurring sympathomimetic amine with vasoconstricting, intraocular pressure-reducing, and bronchodilating activities. By stimulating vascular alpha-adrenergic receptors, epinephrine causes vasoconstriction, thereby increasing vascular resistance and blood pressure. The adrenal glands produce the hormone norepinephrine, a potent form of the “fight or flight” hormone epinephrine. Tumors of the adrenal glands called pheochromocytomas produce abnormally high levels of norepinephrine. The majority of pheochromocytomas are noncancerous. Norepinephrine is produced in the inner part of the adrenal glands, also called the adrenal medulla. The adrenal medulla also makes adrenaline (also known as epinephrine).

Epinephrine Hydrochloride is the hydrochloride salt of the naturally occurring sympathomimetic amine with vasoconstricting, intraocular pressure-reducing, and bronchodilating activities.
Norepinephrine is also released from the majority of postganglionic, sympathetic neurons in the peripheral (autonomic) nervous system. Epinephrine, aka “adrenaline” across the pond, is the sassy little sister to norepinephrine. Like norepi, it is a catecholamine. And like norepi, it avidly binds at alpha-1 adrenergic receptors. Unlike norepi, it is also a potent beta-1 agonist. Epinephrine is also called adrenaline, derived from the name of its gland. For this reason, receptors for both epinephrine and norepinephrine are called adrenergic receptors.
Norepinephrine differs from epinephrine by the absence of a methyl group on the nitrogen atom. Epinephrine is synthesized from norepinephrine within the adrenal glands medulla, which are small glands located above your kidneys. Preganglionic fibers of the sympathetic nervous system synapse within the adrenal glands. How norepinephrine, dopamine and epinephrine work Norepinephrine increases blood pressure by vasoconstriction (alpha effects) and has very little effect on beta until it reaches the higher doses.
