What is BuSpar?

Buspirone is a medication used to treat generalized anxiety disorder or provide short-term anxiety relief in adults.

Although the brand name BuSpar has been discontinued, the drug is still available in its generic form—buspirone. Many people still use BuSpar and buspirone interchangeably to refer to this medication.

How does BuSpar work to relieve anxiety?

Buspirone belongs to the azapirone class of drugs, which includes other anti-anxiety and anti-psychotic medications. 

Buspirone acts on the neurotransmitters of the brain, such as serotonin and dopamine. Serotonin and dopamine are responsible for managing anxiety. The drug increases the action of serotonin receptors. It also has a mild affinity for dopamine receptors, thereby increasing their activity. 

Buspirone is never given as the first line of treatment for treating anxiety and depression; rather, it is typically given as an adjuvant to other mainstream anti-anxiety drugs such as selective serotonin reuptake inhibitors (SSRIs).
