AP PSYCHOLOGY

Detailed explanation-1: -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-2: -Prozac is part of a class of drugs known as SSRIs, or Selective Serotonin Reuptake Inhibitors. These drugs are believed to produce their effect by altering the ease with which Serotonin, a neurotransmitter chemical naturally found in the brain, gets reabsorbed from the synapses (spaces) between brain cells.

Detailed explanation-3: -Fluoxetine is a type of antidepressant known as a selective serotonin reuptake inhibitor (SSRI). It’s often used to treat depression, and sometimes obsessive compulsive disorder and bulimia. It works by increasing the levels of serotonin in the brain.

Detailed explanation-4: -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.
