Noradrenergic and specific serotonergic antidepressants (NaSSAs) are a class of psychiatric drugs used primarily as antidepressants. [1] They act by antagonizing the α 2 -adrenergic receptor and certain serotonin receptors such as 5-HT 2A and 5-HT 2C , [ 1 ] but also 5-HT 3 , [ 1 ] 5-HT 6 , and/or 5-HT 7 in some cases.
Desipramine, sold under the brand name Norpramin among others, is a tricyclic antidepressant (TCA) used in the treatment of depression. [8] It acts as a relatively selective norepinephrine reuptake inhibitor, though it does also have other activities such as weak serotonin reuptake inhibitory, α 1-blocking, antihistamine, and anticholinergic effects.
It is difficult to develop an animal model that perfectly reproduces the symptoms of depression in patients. It is generic that 3 standards may be used to evaluate the reliability of an animal version of depression: the phenomenological or morphological appearances (face validity), a comparable etiology (assemble validity), and healing similarities (predictive validity).
This interaction seems to be critical for increased availability of norepinephrine in or near the synaptic clefts. Actions of imipramine-like tricyclic antidepressants have complex, secondary adaptions to their initial and sustained actions as inhibitors of norepinephrine transport and variable blockade of serotonin transport.
Trazodone, sold under many brand names, [1] is an antidepressant medication [20] used to treat major depressive disorder, anxiety disorders, and insomnia. [20] It is a phenylpiperazine compound of the serotonin antagonist and reuptake inhibitor (SARI) class.
