How does this medicine work on the body?

Simply put, Vortioxetine is a medication used to treat depression. It belongs to the class of drugs called SSRI '' or Selective Serotonin Reuptake Inhibitors''.

Imagine that our brain has a chemical called serotonin that controls our mood , that is, our happiness and calmness. This serotonin level can decrease when we are depressed.

SSRI class of drugs works by increasing the amount of serotonin in the brain and increasing its activity. Vortioxetine also does this. However, this drug changes several serotonin receptors in the brain in a slightly different way than other SSRI. Therefore, it is also called a Serotonin Modulator. Because of this, sometimes it can have different results than other drugs.
