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).
The norepinephrine transporter (NET) serves as the fundamental mechanism for the inactivation of noradrenergic signaling because of the NET termination in the reuptake of norepinephrine (NE). The selectivity and mechanism of action for the NRI drugs remain mostly unresolved and, to date, only a limited number of NRI-selective inhibitors are ...
It shows high affinity for both the norepinephrine transporter (NET) and the serotonin transporter (SERT), with 4-fold selectivity for the NET over the SERT, and is thought to act as a dual serotonin–norepinephrine reuptake inhibitor (SNRI) at higher doses. [4] [1] As of November 2023, ampreloxetine is in phase 3 clinical trials for NOH. [2]
The norepinephrine transporter (NET), also known as noradrenaline transporter (NAT), is a protein that in humans is encoded by the solute carrier family 6 member 2 (SLC6A2) gene. [ 5 ] NET is a monoamine transporter and is responsible for the sodium-chloride (Na + /Cl − )-dependent reuptake of extracellular norepinephrine (NE), which is also ...
OPC-64005 is a serotonin–norepinephrine–dopamine reuptake inhibitor (SNDRI), or "triple reuptake inhibitor" (TRI), which is under development for the treatment of major depressive disorder. [ 1 ] [ 2 ] [ 3 ] It was also under development for the treatment of attention deficit hyperactivity disorder (ADHD), but development for this ...
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. [1]
PRX-14040 is a selective dopamine reuptake inhibitor that was developed by Prexa Pharmaceuticals. [1] [2] [3] It has 28-fold selectivity for the dopamine transporter over the norepinephrine transporter. [2]
3 H-nisoxetine (3 H-NIS), on the other hand, is a potent and selective inhibitor for the uptake of norepinephrine [13] and is now used as a selective marker of the norepinephrine transporter. [14] Most studies using 3 H-NIS are conducted in the rat model, and not many have been performed in humans.
