WebThe main mechanism of action of tricyclic antidepressants is the inhibition or blockade of the so-called"monoamine reuptake pump". Within the monoamines, in this case we talk about the Serotonin And noradrenaline. The reuptake pump is a protein that is located in the membranes of neurons (nerve cells of the brain). WebTricyclic antidepressants (TCAs) have been used for the treatment of a wide variety of neuropathic pain states including PHN. TCAs exert their analgesic effects presumably through blockade of primarily norepinephrine reuptake with other mechanisms possibly including blockade of serotonin reuptake and sodium channels. 72 A recent quantitative ...
