Who is the author of the tricyclic antidepressant?
Tricyclic antidepressants (TCAs) are a class of medications that are used primarily as antidepressants, which is important for the management of depression.They are second-line drugs next to SSRIs. TCAs were discovered in the early 1950s and were marketed later in the decade. They are named after their chemical structure, which contains three rings of atoms.
Why are SSRIs the most commonly used antidepressants?
Tricyclic antidepressants, or TCAs, are pills which are used in order to treat depression. They were discovered for the first time during the early 1950s, and, until recently, these medications were the first choice of many doctors to treat depression. The first TCAs were Imipramine, now popularly known as Tofranil.

What is a tricyclic antidepressant?
Notice its three rings. Tricyclic antidepressants ( TCAs) are a class of medications that are used primarily as antidepressants, which is important for the management of depression.
When were TCAs first discovered?
TCAs were discovered in the early 1950s and were marketed later in the decade. They are named after their chemical structure, which contains three rings of atoms. Tetracyclic antidepressants (TeCAs), which contain four rings of atoms, are a closely related group of antidepressant compounds.
What are the two major groups of TCAs?
The groupings are based on the tricyclic ring system. They are the dibenzazepines ( imipramine, desipramine, clomipramine, trimipramine, lofepramine) and the dibenzocycloheptadienes ( amitriptyline, nortriptyline, protriptyline, butriptyline ). Minor TCA groups based on ring system include the dibenzoxepins ( doxepin ), the dibenzothiepines ( dosulepin ), and the dibenzoxazepines ( amoxapine ). In addition to classification based on the ring system, TCAs can also be usefully grouped based on the number of substitutions of the side chain amine. These groups include the tertiary amines (imipramine, clomipramine, trimipramine, amitriptyline, butriptyline, doxepin, dosulepin) and the secondary amines (desipramine, nortriptyline, protriptyline). Lofepramine is technically a tertiary amine, but acts largely as a prodrug of desipramine, a secondary amine, and hence is more similar in profile to the secondary amines than to the tertiary amines. Amoxapine does not have the TCA side chain and hence is neither a tertiary nor secondary amine, although it is often grouped with the secondary amines due to sharing more in common with them. In 2021, Gorostiza and coll. at Institute for Bioengineering of Catalonia proposed a new method for designing photochromic analogs of tricyclic drugs via isosteric replacement of the two-atom bridge between the aromatic systems with an azo group and opening of the central ring. They named the strategy “crypto-azologization”.
When was imipramine first used?
The first trial of imipramine took place in 1955 and the first report of antidepressant effects was published by Swiss psychiatrist Roland Kuhn in 1957. Some testing of Geigy's imipramine, then known as Tofranil, took place at the Münsterlingen Hospital near Konstanz.

How effective are TCAs?
They are also effective in migraine prophylaxis, though not in the instant relief of an acute migraine attack. They may also be effective to prevent chronic tension headaches.
When were TCAs invented?
The TCAs were developed amid the "explosive birth" of psychopharmacology in the early 1950s. The story begins with the synthesis of chlorpromazine in December 1950 by Rhône-Poulenc 's chief chemist, Paul Charpentier, from synthetic antihistamines developed by Rhône-Poulenc in the 1940s.
