No, it's not new. Buspar is a trade name for Buspirone. It's an anxiolytic that acts in the serotonin and dopamine pathways. I can't say it really did anything for my anxiety but at first it had a stimulant effect that helped increase my productivity, and it also made me more talkative (I can be shy). After a month, these benefits disappeared. I was taking a much lower dose than Brina, however, only 30 mg/day, which is a typical therapeutic dose. Most recently, this drug has been shown to work effectively together with SSRIs to increase their efficacy in reducing symptoms of depression, but not on its own.
