This document discusses anti-anxiety drugs, including their classification, mechanisms of action, and side effects. It begins by defining anxiety and explaining that anti-anxiety drugs, also called anxiolytics, are used to treat pathological anxiety. The main types of anti-anxiety drugs covered are benzodiazepines, which enhance GABA inhibition; azapirones like buspirone, which do not interact with benzodiazepine receptors; beta-blockers that reduce physical symptoms of anxiety; and antidepressants such as SSRIs and SNRIs. Common side effects of anti-anxiety drugs include drowsiness, fatigue, confusion, and dry mouth.
