It is the same molecule as the hormone and neurotransmitter norepinephrine. [2] It is given by slow injection into a vein. [2] Common side effects include headache, slow heart rate, and anxiety. [2] Other side effects include an irregular heartbeat. [2] If it leaks out of the vein at the site it is being given, norepinephrine can result in limb ...
The most common side effects include nausea/vomiting, sweating, loss of appetite, dizziness, headache, increase in suicidal thoughts, and sexual dysfunction. [69] Elevation of norepinephrine levels can sometimes cause anxiety, mildly elevated pulse, and elevated blood pressure.
The first commercially available selective norepinephrine reuptake inhibitor (sNRI) was reboxetine (Edronax) and was developed as a first-line therapy for major depressive disorder. [29] The selectivity of reboxetine for the norepinephrine transporter (NET) results in benign side effect profile because the drug is well tolerated. [11]
Desvenlafaxine is a synthetic form of the isolated major active metabolite of venlafaxine, and is categorized as a serotonin-norepinephrine reuptake inhibitor (SNRI). When most normal metabolizers take venlafaxine, approximately 70% of the dose is metabolized into desvenlafaxine, so the effects of the two drugs are expected to be very similar. [18]
In addition, due to their blockade of certain serotonin receptors, serotonergic neurotransmission is not facilitated in unwanted areas, which prevents the incidence of many side effects often associated with selective serotonin reuptake inhibitor (SSRI) antidepressants; [1] [3] hence, in part, the "specific serotonergic" label of NaSSAs. [2]
Duloxetine is a serotonin–norepinephrine reuptake inhibitor (SNRI). [9] The precise mechanism for its antidepressant and anxiolytic effects is not known. [7] Common side effects include dry mouth, nausea, feeling tired, dizziness, agitation, sexual problems, and increased sweating. [7]
The majority of TCAs exert greater effect on norepinephrine, which leads to side effects like drowsiness and memory loss. [ citation needed ] In order to be more effective on serotonin agonism and avoid anticholinergic and antihistaminergic side effects, selective serotonin reuptake inhibitors (SSRI) were researched and introduced to treat ...
Venlafaxine, sold under the brand name Effexor among others, is an antidepressant medication of the serotonin–norepinephrine reuptake inhibitor (SNRI) class. [6] [9] It is used to treat major depressive disorder, generalized anxiety disorder, panic disorder, and social anxiety disorder. [9]
