How ONYDA XR Works

This medication works by stimulating alpha 2-adrenergic receptors located in the brain. Unlike many other common ADHD treatments, it does not function as a central nervous system stimulant. While the exact way this process improves ADHD symptoms is not known, the drug acts as a centrally acting alpha 2-adrenergic agonist.
