| norepinephrine | Precursor of epinephrine that is secreted by the ADRENAL MEDULLA and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers, and of the diffuse projection system in the brain that arises from the LOCUS CERULEUS. It is also found in plants and is used pharmacologically as a sympathomimetic. |
|
| prazosin | A selective adrenergic alpha-1 antagonist used in the treatment of HEART FAILURE; HYPERTENSION; PHEOCHROMOCYTOMA; RAYNAUD DISEASE; PROSTATIC HYPERTROPHY; and URINARY RETENTION. |
|
| solriamfetol | The mechanism of action of solriamfetol to improve wakefulness in patients with excessive daytime sleepiness associated with narcolepsy or obstructive sleep apnea is unclear. However, solriamfetol binds to the dopamine transporter and norepinephrine transporter with low affinity and inhibits the reuptake of dopamine and norepinephrine with low potency. Solriamfetol has no appreciable binding affinity for the serotonin transporter (Ki=81.5 μM) and does not inhibit serotonin reuptake (IC50 > 100 μM). Solriamfetol improves wakefulness in patients with excessive daytime sleepiness associated with narcolepsy or obstructive sleep apnea is unclear. However, its efficacy could be mediated through its activity as a dopamine and norepinephrine reuptake inhibitor (DNRI). |
|
| desvenlafaxine | The exact mechanism of the antidepressant action of desvenlafaxine is unknown, but is thought to be related to the potentiation of serotonin and norepinephrine in the central nervous system, through inhibition of their reuptake. Non-clinical studies have shown that desvenlafaxine is a potent and selective serotonin and norepinephrine reuptake inhibitor (SNRI). |
|
| levomilnacipran | a selective serotonin and norepinephrine reuptake inhibitor (SNRI), mechanism of the antidepressant action of levomilnacipran is unknown, but is thought to be related to the potentiation of serotonin and norepinephrine in the central nervous system |
|
| guanethidine | An antihypertensive agent that acts by inhibiting selectively transmission in post-ganglionic adrenergic nerves. It is believed to act mainly by preventing the release of norepinephrine at nerve endings and causes depletion of norepinephrine in peripheral sympathetic nerve terminals as well as in tissues. |
|
| mirtazapine | A piperazinoazepine tetracyclic compound that enhances the release of NOREPINEPHRINE and SEROTONIN through blockage of presynaptic ALPHA-2 ADRENERGIC RECEPTORS. It also blocks both 5-HT2 and 5-HT3 serotonin receptors and is a potent HISTAMINE H1 RECEPTOR antagonist. It is used for the treatment of depression, and may also be useful for the treatment of anxiety disorders. |
|
| nefazodone | an antidepressant for oral administration with a chemical structure unrelated to selective serotonin reuptake inhibitors, tricyclics, tetracyclics, or monoamine oxidase inhibitors (MAOI), inhibits neuronal uptake of serotonin and norepinephrine |
|
| phenylalanine | An essential aromatic amino acid that is a precursor of MELANIN; DOPAMINE; noradrenalin (NOREPINEPHRINE), and THYROXINE. |
|
| pyridoxal phosphate | This is the active form of VITAMIN B 6 serving as a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. During transamination of amino acids, pyridoxal phosphate is transiently converted into pyridoxamine phosphate (PYRIDOXAMINE). |
|
| vortioxetine | A piperazine derivative that acts as a serotonin reuptake inhibitor, as a 5-HT3 receptor antagonist, and 5-HT1A receptor agonist. It is used for the treatment of anxiety and depression. |
|
| nordefrin | A norepinephrine derivative used as a vasoconstrictor agent. |
|
| pyridoxine | The 4-methanol form of VITAMIN B 6 which is converted to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. Although pyridoxine and Vitamin B 6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading (EE Snell; Ann NY Acad Sci, vol 585 pg 1, 1990). |
|
| milnacipran | A cyclopropanecarboxamide serotonin and norepinephrine reuptake inhibitor (SNRI) that is used in the treatment of FIBROMYALGIA. |
|
| deutetrabenazine | The precise mechanism by which deutetrabenazine exerts its anti-chorea effects is unknown but is believed to be related to its effect as a reversible depletor of monoamines (such as dopamine, serotonin, norepinephrine, and histamine) from nerve terminals. The major circulating metabolites (alpha-dihydrotetrabenazine [HTBZ] and beta-HTBZ) of deutetrabenazine, are reversible inhibitors of VMAT2, resulting in decreased uptake of monoamines into synaptic vesicles and depletion of monoamine stores. |
|
| pyridoxal | The 4-carboxyaldehyde form of VITAMIN B 6 which is converted to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. |
|
| phenylpropanolamine | A sympathomimetic that acts mainly by causing release of NOREPINEPHRINE but also has direct agonist activity at some adrenergic receptors. It is most commonly used as a nasal vasoconstrictor and an appetite depressant. |
|
| reserpine | An alkaloid found in the roots of Rauwolfia serpentina and R. vomitoria. Reserpine inhibits the uptake of norepinephrine into storage vesicles resulting in depletion of catecholamines and serotonin from central and peripheral axon terminals. It has been used as an antihypertensive and an antipsychotic as well as a research tool, but its adverse effects limit its clinical use. |
|
| femoxetine | serotonin uptake inhibitor; RN given refers to (3R-trans)-isomer |
|
| lofexidine | Lofexidine is a central alpha-2 adrenergic agonist that binds to receptors on adrenergic neurons. This reduces the release of norepinephrine and decreases sympathetic tone. |
|
| dopamine | One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action. |
|
| atomoxetine | A propylamine derivative and selective ADRENERGIC UPTAKE INHIBITOR that is used in the treatment of ATTENTION DEFICIT HYPERACTIVITY DISORDER. |
|
| dapoxetine | selective serotonin reuptake inhibitor (SSRI) that was designed specifically for premature ejaculation |
|
| ephedrine | A phenethylamine found in EPHEDRA SINICA. PSEUDOEPHEDRINE is an isomer. It is an alpha- and beta-adrenergic agonist that may also enhance release of norepinephrine. It has been used for asthma, heart failure, rhinitis, and urinary incontinence, and for its central nervous system stimulatory effects in the treatment of narcolepsy and depression. It has become less extensively used with the advent of more selective agonists. |
|
| iobenguane (131I) | AZEDRA is an I 131 labeled iobenguane. Iobenguane is similar in structure to the neurotransmitter norepinephrine (NE) and is subject to the same uptake and accumulation pathways as NE. Iobenguane is taken up by the NE transporter in adrenergic nerve terminals and accumulates in adrenergically innervated tissues, such as the heart, lungs, adrenal medulla, salivary glands, liver, and spleen as well as tumors of neural crest origin. Pheochromocytoma and paraganglioma (PPGL) are tumors of neural crest origin that express high levels of the NE transporter on their cell surfaces. Following intravenous administration, AZEDRA is taken up and accumulates within pheochromocytoma and paraganglioma cells, and radiation resulting from radioactive decay of I 131 causes cell death and tumor necrosis. |
|
| droxidopa | A synthetic precursor of norepinephrine that is used in the treatment of PARKINSONIAN DISORDERS and ORTHOSTATIC HYPOTENSION. |
|
| viloxazine | A morpholine derivative used as an antidepressant. It is similar in action to IMIPRAMINE. The mechanism of action of viloxazine in the treatment of ADHD is unclear; however, it is thought to be through inhibiting the reuptake of norepinephrine. |
|
| Ioflupane I-123 | Ioflupane binds reversibly to the human recombinant dopamine transporter (DaT). Following administration of DaTscan to humans, radioactive decay of the iodine 123 emits gamma radiation which can be detected externally using gamma detectors, allowing visualization of the brain striata through SPECT imaging. Autoradiography of post-mortem human brain slices exposed to radiolabeled ioflupane shows concentration of the radiolabel in striatum (caudate nucleus and putamen). The specificity of the binding of ioflupane I 125 to dopamine transporter was demonstrated by competition studies with the DaT inhibitor GBR 12909 (a dopamine reuptake inhibitor), the serotonin reuptake inhibitor citalopram, and the norepinephrine reuptake inhibitor desipramine in post-mortem human brain slices exposed to radiolabeled ioflupane. Citalopram reduced binding in the neocortex and thalamus with only minor effects in the striatum. This indicated that the binding in the cortex and thalamus is mainly to the serotonin reuptake sites. Desipramine showed no effect on the level of striatal binding of ioflupane I 125, but reduced extrastriatal binding by 60 to 85%. The binding of ioflupane I 125 to the striatum was abolished in the presence of high concentrations of GBR 12909, indicating selectivity of ioflupane binding for the pre-synaptic DaT. |
|
| desipramine | A tricyclic dibenzazepine compound that potentiates neurotransmission. Desipramine selectively blocks reuptake of norepinephrine from the neural synapse, and also appears to impair serotonin transport. This compound also possesses minor anticholinergic activity, through its affinity to muscarinic receptors. |
|
| nomifensine | An isoquinoline derivative that prevents dopamine reuptake into synaptosomes. The maleate was formerly used in the treatment of depression. It was withdrawn worldwide in 1986 due to the risk of acute hemolytic anemia with intravascular hemolysis resulting from its use. In some cases, renal failure also developed. (From Martindale, The Extra Pharmacopoeia, 30th ed, p266) |
|
| fluoxetine | The first highly specific serotonin uptake inhibitor. It is used as an antidepressant and often has a more acceptable side-effects profile than traditional antidepressants. |
|
| sibutramine | serotonin and norepinephrine transporter inhibitor; Meridia is tradename for sibutramine hydrochloride |
|
| reboxetine | A morpholine derivative that is a selective and potent noradrenaline reuptake inhibitor; it is used in the treatment of DEPRESSIVE DISORDER. |
|
| entacapone | Entacapone is a selective and reversible inhibitor of COMT. COMT catalyzes the transfer of the methyl group of S-adenosyl-L-methionine to the phenolic group of substrates that contain a catechol structure. Physiological substrates of COMT include dopa, catecholamines (dopamine, norepinephrine, and epinephrine) and their hydroxylated metabolites. The function of COMT is the elimination of biologically active catechols and some other hydroxylated metabolites. When entacapone is given in conjunction with levodopa and an aromatic amino acid decarboxylase inhibitor, such as carbidopa, plasma levels of levodopa are greater and more sustained than after administration of levodopa and an aromatic amino acid decarboxylase inhibitor alone. It is believed that at a given frequency of levodopa administration, these more sustained plasma levels of levodopa result in more constant dopaminergic stimulation in the brain, leading to greater effects on the signs and symptoms of Parkinson's disease. |
|
| serdexmethylphenidate | Serdexmethylphenidate is a prodrug of dexmethylphenidate (d-MPH). The mode of therapeutic action in ADHD is not known. Serdexmethylphenidate is not deemed to have pharmacological activity until converted to d-MPH. Dexmethylphenidate HCl is a central nervous system (CNS) stimulant that blocks the reuptake of norepinephrine and dopamine into the presynaptic neuron and increase the release of these monoamines into the extraneuronal space. |
|
| amoxapine | The N-demethylated derivative of the antipsychotic agent LOXAPINE that works by blocking the reuptake of norepinephrine, serotonin, or both; it also blocks dopamine receptors. Amoxapine is used for the treatment of depression. |
|
| paroxetine | A serotonin uptake inhibitor that is effective in the treatment of depression. |
|
| amitriptyline | Tricyclic antidepressant with anticholinergic and sedative properties. It appears to prevent the re-uptake of norepinephrine and serotonin at nerve terminals, thus potentiating the action of these neurotransmitters. Amitriptyline also appears to antagonize cholinergic and alpha-1 adrenergic responses to bioactive amines. |
|
| duloxetine | A thiophene derivative and selective NEUROTRANSMITTER UPTAKE INHIBITOR for SEROTONIN and NORADRENALINE (SNRI). It is an ANTIDEPRESSIVE AGENT and ANXIOLYTIC, and is also used for the treatment of pain in patients with DIABETES MELLITUS and FIBROMYALGIA. |
