Basically, in depressive patients, we have low concentration of monoamines in the form of epinephrine and serotonine. So, by combining TCAs (an antidepressant) with biogenic-amines (epinephrine, norepinephrine, dopamine), they may potentiate each other.

Yes, of course, actually SSRIs will likely have fewer and less intense side-effects than TCAs. Advise your doctor on how fast you will discontinue the TCA, how much you will wait (if at all), and how much you will start the SSRI.
The drug that inhibits the reuptake of dopamine, serotonin, and norepinephrine into presynaptic axon terminals is a type of antidepressant medication known as a tricyclic antidepressant (TCA). Examples of TCAs include amitriptyline, imipramine, and nortriptyline. By blocking the reuptake of these neurotransmitters, TCAs increase their levels in the brain, which can help alleviate symptoms of depression.
some use a system called TCAS (Traffic Collision Avoidance System), but others have to rely on the ATC (Air Traffic Control).
Yes. Many of todays aircraft have onboard weather, ground proximity and traffic collision radar (TCAS) systems. Each of these is used to determine outside conditions in visual and instrument flight conditions.
No. Bupropion (aka Wellbutrin) is known as an atypical antidepressant in that it prevents the reuptake of serotonin, norepinephrine, and dopamine (to a lesser extent). Typical tricyclic antidepressants only block reuptake of serotonin and norepinephrine. It's unique dopamine reuptake inhibition capability allows it to be used to treat nicotine addiction (marketed as Zyban) and, to some extent, attention deficit disorder. Furthermore, it lacks the classic three ring chemical structure of tricyclic antidepressants (TCAs). Here are a list of some common TCAs: imipramine (tofranil) amitriptyline (Elavil/Endep) doxepin (adapin) nortrypyline (Pamelor), etc
As part of an ongoing treatment study of co-occurring bipolar mania and cannabis abuse in adolescents, we obtained bi-monthly urine toxicology screens using the Status DS™ immunoassay. It was noted that the first five subjects initially tested negative for tricylcic antidepressants (TCAs) but all five tested positive after being treated with topiramate or placebo and quetiapine. All of the patients denied using TCAs, but were forthcoming regarding their drug use. A quetiapine trough blood level was also obtained on the same morning that the urine toxicology screens were performed and the results paralleled the TCA toxicology findings, i.e., when subjects showed quetiapine in their serum (5.1 to 85 ng/ml), they tested positive for TCAs. However, when two of the subjects were non-adherent to their medications and their quetiapine levels were undetectable, their toxicology screens were negative for TCAs. After these two patients were encouraged to take their medications and had detectable quetiapine levels, they once again tested positive for TCIt looks like Seroquel will show up as a positive for TCA panel.
The simple answer to this is believed to be through potentiation of endogenous opioid activity, though this is uncertain. SNRIs (not NSRIs) are essentially selective versions of TriCyclic Antidepressants. There is evidence that TCAs potentiate opioid analgaesia, which could be the mechinism of action.
On the ground and in the air, commercial aircraft are controlled by the Air Traffic Controllers. Aircraft are separated by altitude and if you happen to be flying faster than another aircraft on the same heading, you just keep on going and pass it. There are conventions for light aircraft and when close to an airfield when not being controlled and there are 'rules' for TCAS systems which consider the aircraft performance when resolution for conflicts is generated.
