Selective Serotonin Reuptake Inhibitors (SSRI)

Selective Serotonin Reuptake Inhibitors, also known as SSRIs, are a class of psychotropic drugs that were created to effect specific biological targets. They are widely used to treat depression by inhibiting, or slowing, the reuptake of the neurotransmitter, serotonin thereby allowing the serotonin to have a greater and more long-lasting effect on the brain synapses. Serotonin is believed to be an important arbiter of positive mood or "happiness."
