Both drugs affect the serotonin transporter (like an SSRI) but also affect other serotonin receptors to relieve major depression. Serotonin and norepinephrine reuptake inhibitors (SNRIs) are among the newer types of antidepressant. As the name implies, they block the reuptake of both serotonin and norepinephrine.
Besides, what does a SNRI do?
Depression is associated with low levels of serotonin and norepinephrine. It is thought that SNRIs help treat depression by keeping up the levels of these two chemical messengers in your brain. They do this by stopping serotonin and norepinephrine from going back into the cells that released them.
Is fluoxetine and SSRI?
Fluoxetine, also known by trade names Prozac and Sarafem, among others, is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. It is used for the treatment of major depressive disorder, obsessive–compulsive disorder (OCD), bulimia nervosa, panic disorder and premenstrual dysphoric disorder.
Do SNRI’s cause weight gain?
In fact, Meridia, a weight-loss drug, is an SNRI. Another SNRI, Effexor, has no weight-loss properties, but it is an antidepressant. This shows that tiny changes in chemical structure can have big effects on the brain.” Fernstrom also adds that Prozac, Celexa, and Lexapro do not cause weight gain.
