What is the difference between and SSRI and a tetracyclic anti depressent?

Question

How do each work?..... and what one is better for what kind of case of mental illness or depression?

Answer 1

All you really need to know is SSRIs are newer, more effective and have fewer side effects and drug interactions. Some of the old tricyclics are still used, mostly for off label purposes like OCD.

Answer 2

From the little info I found, it looks like tetracyclic antidepressants are more effective on norepinephrine and less effective on serotonin, while SSRIs only increase the amount of serotonin in the brain.

Answer 3

both aren't from now on mutually unique. inspite of the indisputable fact that, i have been questioning if there's a ideal time period for being anti-non secular. i'm a lot extra anti-non secular than i'm anti-theist. yet I basically call myself atheist because its the nearest. i imagine the precise thanks to describe me might want to be strongly anti-non secular, contextualy dependant atheist agnostic (i'm hostile to any kind of theistic faith, i do not options religions like buddhism. I strongly disbelieve contained in the portrayals of God by the universal religions even although i don't have sturdy data, yet well known the possibility that there might want to nicely be some kind of larger rigidity that would want to nicely be referred to as a god.) Anti non secular propose that the man is hostile to the concept of an company outfitted round a conception equipment, yet they could have any perspective of the existance of a god. Anti theistic signifies that the man is hostile to the idea of a god, besides the very incontrovertible truth that anti theists are often anti-non secular aswell. I dare to assert maximum atheists on listed the following are probably extra probably to be anti non secular than anti theistic in protecting with solutions i have considered to R&S questions. maximum all and multiple is basically attempting to loose theists from the tyranny of organised faith which basically serves to take advantage and administration them and their beliefs.

Answer 4

SSRIs target serotonin or 5HT. TCAs are a much older class of drug, with more side-effects, that work with norepinephrine (if i recall correctly).
