What is Buspirone?
Buspirone is an anti-anxiety medication. It was sold under the trade name BuSpar, which has been discontinued in the U.S. Buspirone is still available as a prescription medication in generic form.
What is Buspirone Used For?
Buspirone is used for treating anxiety disorders or for short-term relief from anxiety symptoms. It has also shown potential effectiveness at helping ease symptoms of attention deficit hyperactivity disorder (ADHD), as well as depression in those with generalized anxiety disorder (GAD).
How Does Buspirone Work?
Buspirone is taken to provide individuals with clearer thinking, reduce irritability, and promote relaxation. The exact mechanism of action for buspirone is not known. Based on in vitro studies, buspirone has shown a tendency to interact with serotonin receptors and D2-dopamine receptors, which are associated with mood improvements. In vitro studies have shown that it does not interact much with benzodiazepine receptors or gamma-aminobutyric acid (GABA) receptors. More research is needed to understand how buspirone helps ease anxiety symptoms.
