Fetzima, also known by its generic name levomilnacipran, belongs to the drug class of serotonin-norepinephrine reuptake inhibitors (SNRIs) [1]. This class of medications works by increasing the levels of serotonin and norepinephrine in the brain, which are neurotransmitters that play a role in mood regulation [2].
What is Fetzima used to treat?
Fetzima is indicated for the treatment of major depressive disorder (MDD) in adults [1]. By affecting serotonin and norepinephrine levels, it helps to alleviate symptoms associated with depression, such as persistent sadness, loss of interest, and changes in sleep or appetite [2].
How do SNRIs like Fetzima work?
SNRIs function by blocking the reuptake, or reabsorption, of serotonin and norepinephrine into neurons [2]. This blockage leads to a higher concentration of these neurotransmitters in the synaptic cleft, the space between neurons, allowing them to bind more effectively to receptors and transmit signals. This enhanced neurotransmission is believed to be responsible for the antidepressant effects of these drugs [1][2].
What other medications are in the SNRI class?
Other medications classified as SNRIs include venlafaxine (Effexor XR), duloxetine (Cymbalta), and desvenlafaxine (Pristiq) [2]. Each of these drugs has a slightly different chemical structure and may have variations in their potency and specificity for serotonin and norepinephrine transporters, potentially leading to differing side effect profiles and efficacy in certain individuals [1][2].
What are the potential side effects of Fetzima?
Common side effects associated with Fetzima include nausea, constipation, increased sweating, and insomnia [1]. As with other SNRIs, there is also a risk of increased blood pressure and heart rate, as well as potential for withdrawal symptoms if the medication is stopped abruptly [2].
How does Fetzima compare to other antidepressants?
Fetzima's efficacy and side effect profile are often compared to other antidepressants, including other SNRIs and selective serotonin reuptake inhibitors (SSRIs) [2]. The choice of antidepressant is typically individualized based on a patient's specific symptoms, medical history, and potential for side effects.
When does Fetzima's patent expire?
