What is the function of serotonin modulators in treating depression?

Serotonin modulators play a crucial role in treating depression primarily by increasing the levels of serotonin in the brain. Serotonin is a neurotransmitter that is closely associated with mood regulation, and many forms of depression are linked to imbalances in serotonin levels. By enhancing serotonin availability, these medications can help alleviate depressive symptoms, leading to improved mood and emotional well-being.

While some treatment options also aim to stabilize mood or influence other neurotransmitters like dopamine, the primary action of serotonin modulators is to facilitate more robust and effective serotonergic signaling. This increased serotonergic activity contributes directly to the therapeutic effects desired in treating depressive disorders.
