When was the first antidepressant discovered?
The 1950s saw the clinical introduction of the first two specifically antidepressant drugs: iproniazid, a monoamine-oxidase inhibitor that had been used in the treatment of tuberculosis, and imipramine, the first drug in the tricyclic antidepressant family.

What antidepressants were used in the 1980s?
SSRIs were introduced in the 1980s, and shortly thereafter they became some of the most commonly used antidepressants, primarily because they have fewer side effects than tricyclics or MAOIs. SSRIs include fluoxetine (Prozac), paroxetine (Paxil), and sertraline (Zoloft).
When were SSRIs invented?
SSRI Antidepressants Selective serotonin reuptake inhibitors were introduced to the market in 1987, with the introduction of Fluoxetine. The SSRIs were almost instantly popular because they were much safer. These drugs increase the amount of serotonin available in the brain.
Which is better SSRI or tricyclic?
SSRIs are more selective for serotonin transporters. While they are usually associated with fewer side effects, SSRIs can still cause adverse effects. Usually, SSRIs are much easier to tolerate than tricyclic antidepressants since the side effect profile is better for most people.
Are tricyclics better than SSRIs?
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.
What antidepressants were used in the 1970’s?
Tetracyclic antidepressants (TeCAs) are a class of antidepressants that were first introduced in the 1970s. They are named after their chemical structure, which contains four rings of atoms, and are closely related to the tricyclic antidepressants (TCAs), which contain three rings of atoms.

Is imipramine a tricyclic antidepressant?
A congener of this compound, imipramine, was discovered by clinical observation to have unexpected antidepressant effects. The clinical success of this drug (which is still in use) led to the development of a successful series of other tricyclic and non-tricyclic antidepressants.
