The Mechanism of Action Explained

The mechanism of action of desvenlafaxin is based on its ability to inhibit serotonin and norepinephrine reuptake. Serotonin and norepinephrine are neurotransmitters that play a fundamental role in mood regulation and general mental wel l-being. When blocking its reuptake, the desvenlafaxin guarantees that these neurotransmitters remain in the synaptic cleft for a longer time, which increases neurotransmission and improves the stabilization of mood.

Block appointment: The inhibition of serotonin and norepinephrine reuptake due to desvenlafaxin is mediated by its active metabolite, O-dissemelvenlafaxin. This metabolite has a greater affinity for serotonin and norepinephrine transporters, effectively preventing the reuptake of these neurotransmitters in the presynaptic neuron.

Block appointment: In addition, desvenlafaxin modulates the activity of certain brain receptors, such as alpha-1 adrenergic receptors. When blocking these receptors, desvenlafaxin acts on adrenergic receptors. By blocking these receptors, norepinephrine levels in synaptic cleft increases even more, which contributes to its antidepressant effects.

It is important to note that the mechanism of action of the desvenlafaxin differs from that of selective serotonin reuptake (SSRS) inhibitors, which act mainly on serotonin reuptake. Its double inhibition of serotonin and norepinephrine reuptake distinguishes it from the SSFS, which makes it an adequate option for patients who do not respond optimally to the SSRS alone.

  • Increase in serotonin and norepinephrine neurotransmission
  • Improves the stabilization of mood and relief of depressive symptoms
  • Modulation of alpha-1 adrenergic receptors to increase norepinephrine activity.
