Copyright © 2007 by The McGraw-Hill Companies, Inc. All rights reserved. Chapter 7 Classes of Medications for Anxiety Disorders Benzodiazepines. These drugs were often used to treat anxiety disorders from the 1960s until the 1980s. They act on GABA, which seems to play a role in fear. They generally work quickly, but due to concerns about abuse or dependency, other medications are now more commonly prescribed. Tricyclic antidepressants (TCAs). These medications were developed in the 1950s and 1960s. They help prevent reuptake of 5HT and NE, but they also affect other neurotransmitters and can have serious side effects. They are not as commonly prescribed in the United States as are newer classes of antidepressants. Monoamine oxidase inhibitors (MAOIs). The MAOIs were developed at about the same time as the TCAs, but they are believed to work differently. They seem to stop the brain from breaking down 5HT and NE after reuptake. Selective serotonin reuptake inhibitors (SSRIs). The SSRIs prevent reuptake of neurotransmitters in the brain. Although the various SSRIs seem to work in basically the same way and have similar side effects, people seem to respond differently to different SSRIs. Serotonin-norepinephrine reuptake inhibitors (SNRIs). Developed in the 1990s, Effexor XR ® (venlafaxine HCl) was the first SNRI. It works on 5HT, like an SSRI, but also helps prevent reuptake of NE.
