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: -SSRIs-such as Lexapro, Celexa, Zoloft, Paxil and Prozac-are believed to alleviate symptoms of depression, excessive worry and compulsivity by acting upon the brain’s chemistry-specifically by blocking the breakdown and reabsorption of the neurotransmitter serotonin in the spaces between neurons.

Detailed explanation-3: -Venlafaxine blocks the neuronal reuptake of serotonin, noradrenaline, and, to a lesser extent, dopamine in the central nervous system. In contrast with several other antidepressant drugs, venlafaxine can induce a rapid onset of action mainly due to a subsequent norepinephrine reuptake inhibition.

Detailed explanation-4: -Introduction. Selective serotonin reuptake inhibitors (SSRIs) are a widely used type of antidepressant medication. They’re mainly prescribed to treat depression, particularly persistent or severe cases, and are often used in combination with a talking therapy such as cognitive behavioural therapy (CBT).

Detailed explanation-5: -It works by increasing the levels of serotonin in the brain. Serotonin is thought to have a good influence on mood, emotion and sleep. Fluoxetine helps many people recover from depression, and it has fewer side effects than some other antidepressants.
