Norepinephrine Epinephrine. 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).
In the use of atomoxetine in children (6 years or older up to 70 kg) with attention-deficit hyperactivity disorder, acute treatment should be started with approximately 0.5 mg/kg orally daily. The dose should be increased after a minimum of 3 days up to approximately 1.2 mg/kg daily (target dose) as a single or two divided doses (in the morning ...
Patients taking strong dopaminergic antagonists such as those used in the treatment of psychosis are more likely than the general population to develop symptoms of depression. [ 210 ] Data from clinical studies have shown that DA agonists, such as bromocriptine , pramipexole and ropinirole , exhibit antidepressant properties.
Noradrenaline itself is widely used as an injectable drug for the treatment of critically low blood pressure. Stimulants often increase, enhance, or otherwise act as agonists of norepinephrine. Drugs such as cocaine and methylphenidate act as reuptake inhibitors of norepinephrine, as do some antidepressants, such as those in the SNRI class.
Noradrenergic and specific serotonergic antidepressants (NaSSAs) are a class of psychiatric drugs used primarily as antidepressants. [1] They act by antagonizing the α 2 -adrenergic receptor and certain serotonin receptors such as 5-HT 2A and 5-HT 2C , [ 1 ] but also 5-HT 3 , [ 1 ] 5-HT 6 , and/or 5-HT 7 in some cases.
Methylphenidate, one of the most widely used NDRIs. A norepinephrine–dopamine reuptake inhibitor (NDRI) is a type of drug that inhibits the reuptake of the monoamine neurotransmitters norepinephrine and dopamine and thereby increases extracellular levels of these neurotransmitters and noradrenergic and dopaminergic neurotransmission.

Sympathomimetic drugs are used to treat cardiac arrest and low blood pressure, or even delay premature labor, among other things. These drugs can act through several mechanisms, such as directly activating postsynaptic receptors , blocking breakdown and reuptake of certain neurotransmitters, or stimulating production and release of catecholamines.
Norepinephrine, also known as noradrenaline and sold under the brand name Levophed among others, is a medication used to treat people with very low blood pressure. [2] It is the typical medication used in sepsis if low blood pressure does not improve following intravenous fluids . [ 3 ]
