As for the origin of the disease, except in some cases where depression is associated with other diseases such as Parkinson's, The main cause of this disorder is an alteration of neurotransmitters in the central nervous system.

The neurotransmitter that has more involvement in the development of depression is serotonin.

Serotonin is considered by some researchers as the chemical responsible for maintaining the balance of our mood. Therefore, a serotonin deficit leads to depressive states.

However, there are also other neurotransmitters such as norepinephrine or dopamine that, by modifying their levels, they favor the appearance of this mood disorder.

How does sertraline exert its effect on the body?

As we know, sertraline is a serotonin reuptake inhibitor. Further, It is highly selective with minimal effects on the reuptake of norepinephrine, unlike many tricyclic antidepressants.

In other words, serotonin, like other neurotransmitters, it is secreted by a neuron to bind with the membrane receptors of another Adjacent neuron and trigger an effect.

Then, it is released from this receptor and some molecules return to the neuron that previously secreted it by a reuptake process. It is in this process that sertraline exerts its effect, inhibiting it. Thus, serotonin is not recaptured and increases its concentration in the presynaptic space between one neuron and another.

Having more serotonin, it can rejoin membrane receptors of the neuron and trigger more effect.

Also, as we have seen, It has a low affinity for other types of biogenic amines receptors, such as norepinephrine. This fact would explain that it has fewer adverse effects than other serotonin reuptake inhibitor drugs.
