But in someone with an anxiety disorder, the cell that released the serotonin may reabsorb it too quickly. As a result, there may not be enough serotonin available to bind to the next cell and allow the signal to pass. SSRIs slow the reuptake of serotonin, leaving more of this neurotransmitter in the synapse. This permits it to work for a longer time, improving the transmission of nerve impulses. | Newer Antidepressants | | Generic name (brand name) | Side effects | bupropion (Wellbutrin) | Anxiety; dry mouth;
