Tetracyclic antidepressants (TeCAs) are a class of antidepressants that were first introduced in the 1970s. They are named after their tetracyclic chemical structure , containing four rings of atoms , and are closely related to the tricyclic antidepressants (TCAs), which contain three rings of atoms.

Mirtazapine, a tetracyclic antidepressant. Tetracyclics are cyclic chemical compounds that contain four fused rings of atoms, for example, Tröger's base . Some tricyclic compounds having three fused and one tethered ring (connected to main nucleus by a single bond) can also classified as tetracyclic, for example, ciclazindol .
Antidepressants are prescribed to treat major depressive disorder (MDD), anxiety disorders, chronic pain, and some addictions. Antidepressants are often used in combination with one another. [1] Despite its longstanding prominence in pharmaceutical advertising, the idea that low serotonin levels cause depression is not supported by scientific ...
The TCAs are used primarily in the clinical treatment of mood disorders such as major depressive disorder (MDD), dysthymia, and treatment-resistant variants. They are also used in the treatment of a number of other medical disorders, including cyclic vomiting syndrome (CVS) and anxiety disorders such as generalized anxiety disorder (GAD), social phobia (SP) also known as social anxiety ...
Mianserin is a tetracyclic piperazinoazepine. Mirtazapine was developed by the same team of organic chemists and differs via addition of a nitrogen atom in one of the rings. [ 43 ] [ 44 ] ( S )-(+)-Mianserin is approximately 200–300 times more active than its enantiomer ( R )-(−)-mianserin; hence, the activity of mianserin lies in the ( S ...
