Sympatholytic

A sympatholytic (sympathoplegic) drug is a medication that reduces activity of the sympathetic nervous system (SNS). They are indicated for various conditions; for example, they may be used to treat high blood pressure. They are also used to treat anxiety, such as generalized anxiety disorder, panic disorder and PTSD. In some cases, such as with guanfacine, they have also shown to be beneficial in the treatment of ADHD.
