Detailed explanation-1: -SSRIs treat depression by increasing levels of serotonin in the brain. Serotonin is one of the chemical messengers (neurotransmitters) that carry signals between brain nerve cells (neurons). SSRIs block the reabsorption (reuptake) of serotonin into neurons.
Detailed explanation-2: -Medications Examples of SSRIs include fluoxetine (Prozac) and sertraline (Zoloft). These drugs are effective for increasing serotonin and can treat symptoms of depression.
Detailed explanation-3: -Because the norepinephrine and serotonin don’t bind to the receptors, they seem to build up in the areas between the nerve cells. As a result, the neurotransmitter levels rise.
Detailed explanation-4: -After carrying a message, serotonin is usually reabsorbed by the nerve cells (known as “reuptake"). SSRIs work by blocking ("inhibiting") reuptake, meaning more serotonin is available to pass further messages between nearby nerve cells.
