Conclusions: Overall efficacy between the two classes is comparable but SSRIs are not proven to be as effective as TCAs in in-patients and against amitriptyline. SSRIs have a modest advantage in terms of tolerability against most TCAs.
Also, combining tricyclic antidepressants (TCAs) and SSRIs can result in exacerbated tricyclic side effects due to elevated TCA blood levels; these occur because of the effects of SSRIs on the P450 2D6 liver enzyme system which can result in a blockade of the metabolism of TCAs.
Are tricyclics more sensitive than SSRIs?
TCAs were significantly more effective than SSRIs (effect size = -0.23, 95% CI -0.40 to -0.05, P = 0.011), although sensitivity analyses by analysing larger studies (> 100 patients) and those providing complete data reduced the advantage to TCAs to a trend (P < 0.10).

Tricyclic antidepressants, or TCAs, were first used to manage major depression. They are believed to block the reuptake of the monoamine neurotransmitters—including serotonin and norepinephrine.
What is the mechanism of action of tricyclic antidepressants?
Mechanism of Action Tricyclic antidepressants act on approximately five different neurotransmitter pathways to achieve their effects. They block the reuptake of serotonin and norepinephrine in presynaptic terminals, which leads to increased concentration of these neurotransmitters in the synaptic cleft.30 Nov 2021
When should you take tricyclic antidepressants?
Taking these medications at bedtime may help. Amitriptyline, doxepin, imipramine and trimipramine are more likely to cause weight gain than other tricyclic antidepressants are.

Which tricyclic antidepressant is best for anxiety?
Physicians use tricyclic antidepressants in the treatment of panic disorder, PTSD, generalized anxiety and depression that occurs with anxiety. Of this family, imipramine has been the focus of most of the panic treatment research.
What is the effect of tricyclic antidepressants?
Tricyclic antidepressants increase levels of norepinephrine and serotonin, two neurotransmitters, and block the action of acetylcholine, another neurotransmitter. Scientists believe that by restoring the balance in these neurotransmitters in the brain that tricyclic antidepressants alleviate depression.
What are 3 common anticholinergic side effects of tricyclic antidepressants?
