Each of these types of medications treat anxiety in different ways, according to the Anxiety and Depression Association of America. SSRIs block the reabsorption of serotonin by certain brain cells, leaving more serotonin in the brain to subsequently boost mood. SNRIs work similarly to SSRIs, but they target norepinephrine transmitters in addition to seratonin transmitters. Benzodiazepines work by decreasing muscle tension and encouraging relaxation, while tricyclic antidepressants block the absorption of serotonin and epinephrine in the brain, states WebMD.
