  Antidepressant effect of norepinephrine uptake 2 inhibitors and combined medications including them - Patent 6403645
Norepinephrine uptake 2 inhibitors (or their precursors) are administered to enhance the effect of norepinephrine reuptake inhibitors and other antidepressants.
One therapy for clinical depression is administration of drugs known as norepinephrine reuptake inhibitors, such as imipramine, desipramine, or reboxetine, which inhibit the reuptake of norepinephrine into the presynaptic neuron ("uptake 1"), the main mechanism of inactivating norepinephrine at the synapse.
The uptake 2 inhibitor or precursor may be normetanephrine or a normetanephrine precursor that crosses the blood-brain barrier where it is converted to normetanephrine, the latter being a norepinephrine uptake 2 inhibitor that increases the level of extraneuronal norepinephrine in the brain.

 norepinephrine reuptake inhibitor - Search Results - MSN Encarta
- norepinephrine removal blocker: a drug, often an antidepressant, that blocks the removal of the neurotransmitter norepinephrine from the synaptic gap, thus increasing its local concentration.
One well-known example is the drug fluoxetine (Prozac), which blocks the reuptake of serotonin.
Another group of antidepressants, known as selective serotonin reuptake inhibitors (SSRI), became available in 1987.

 Serotonin-norepinephrine reuptake inhibitor - Voyager, the free encyclopedia   (Site not responding. Last check: 2007-10-31)
Serotonin norepinephrine reuptake inhibitors (SNRIs) are a class of antidepressant used in the treatment of clinical depression and other affective disorders.
Activity on norephinephine reuptake is thought necessary for an antidepressant to be effective on neuropathic pain, a property shared with the older tricyclic antidepressants but not with the SSRIs.
Modern antidepressants usually achieve this effect by blocking the transporter proteins that reabsorb certain neurotranmitters, hence the name "reuptake inhibitors".

 Cymbalta, Duloxetine Hydrochloride Pharmacology - HealthyPlace.com
Preclinical studies have shown that duloxetine is a potent inhibitor of neuronal serotonin and norepinephrine reuptake and a less potent inhibitor of dopamine reuptake.
Inhibitors of CYP1A2 — When duloxetine was co-administered with fluvoxamine, a potent CYP1A2 inhibitor, to male subjects (n=14) the AUC was increased approximately 6-fold, the Cmax was increased about 2.5-fold, and duloxetine t1/2 was increased approximately 3-fold.
Inhibitors of CYP2D6 — Because CYP2D6 is involved in duloxetine metabolism, concomitant use of duloxetine with potent inhibitors of CYP2D6 would be expected to, and does, result in higher concentrations of duloxetine (see PRECAUTIONS, Drug Interactions).

 RemedyFind: patient ratings of Cymbalta etc. (Duloxetine) for Depression
Unlike “selective serotonin reuptake inhibitors” (SSRI’s) such as Prozac etc. (Fluoxetine), Paxil (Paroxetine) etc., which only balance levels of the nerve transmitter serotonin, SSNRI’s have the ability to affect two neurotransmitters - serotonin and norepinephrine.
Clinical studies have shown that the SSNRI’s are generally quicker acting and more effective in treating severe major depressive disorder, treatment-resistant depression, and depressive symptom remission than SSRI antidepressants, and tricyclic antidepressants.
Neurotransmitters like serotonin and norepinephrine (also known as noradrenaline), are involved in the regulation of pain, pleasure, anxiety, panic, arousal, and sleep behavior (the sleep-wake cycle).

Of these, only the stimulants and the selective norepinephrine reuptake inhibitor have been approved by the U.S. Food and Drug Administration (FDA) for treating AD/HD in children.
Scientists believe it works by blocking or slowing the reuptake of norepinephrine, a neurotransmitter that regulates attention, impulsivity, and activity levels in the brain.
Important Note: In September of 2004, an expert panel advising the U.S. Food and Drug Administration recommended that the SSRI (Selective Seratonin Reuptake Inhibitor) category of anti-depressants carry a warning on their labels saying that these medications can sometimes lead children and teenagers to become suicidal.
