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).
Norepinephrine is a catecholamine and a phenethylamine. [4] Its structure differs from that of epinephrine only in that epinephrine has a methyl group attached to its nitrogen, whereas the methyl group is replaced by a hydrogen atom in norepinephrine. [4]
Beta blockers inhibit these normal epinephrine- and norepinephrine-mediated sympathetic actions, [3] but have minimal effect on resting subjects. [citation needed] That is, they reduce the effect of excitement or physical exertion on heart rate and force of contraction, [68] and also tremor, [69] and breakdown of glycogen. Beta blockers can ...
This property of SNRIs might be used to reduce doses of other pain relieving medication and lower the frequency of safety, limited efficacy and tolerability issues. [45] Clinical research data have shown in patients with GAD that the SNRI duloxetine is significantly more effective than placebo in reducing pain-related symptoms of GAD, after ...
Antidepressants can include SSRIs (which increase serotonin levels in the brain), SNRIs (which increase serotonin and norepinephrine), and atypical antidepressants (Wellbutrin, for example), along ...
Reboxetine, sold under the brand name Edronax, [3] is a selective norepinephrine reuptake inhibitor and acts by binding to the NET and block the reuptake of norepinephrine in the extracellular fluids. Its indication is for acute treatment of depression or major depression disorder. Reboxetine was first approved for marketing in Europe in 1997 ...

Desipramine, sold under the brand name Norpramin among others, is a tricyclic antidepressant (TCA) used in the treatment of depression. [8] It acts as a relatively selective norepinephrine reuptake inhibitor, though it does also have other activities such as weak serotonin reuptake inhibitory, α 1-blocking, antihistamine, and anticholinergic effects.
