Buspirone

What is Buspirone?

Buspirone is an anti-anxiety medication used primarily to treat generalized anxiety disorder (GAD) and, in some cases, other anxiety disorders. Unlike other anxiolytics such as benzodiazepines, buspirone does not cause significant sedation and has a low potential for abuse or dependence. This medication is marketed under the name BusPar® and other generic names.

How Does Buspirone Work?

Buspirone acts on the central nervous system, specifically on the brain's serotonin and dopamine receptors. Although its exact mechanism of action is not fully understood, buspirone is believed to work as a partial agonist of the serotonin 5-HT1A receptor and to have modulatory effects on dopamine D2 receptors. These effects help reduce anxiety symptoms by improving the balance of neurotransmitters in the brain.
