ONYDA XR (clonidine hydrochloride) · TRIS PHARMA INC

CNS Approved 2024-05-24

ONYDA XR treats Attention Deficit Hyperactivity Disorder (ADHD) in pediatric patients aged six years and older. It is used as a standalone therapy or as an addition to central nervous system stimulant medications to help patients manage their symptoms. This medication provides a non-stimulant option for children and adolescents requiring treatment for ADHD.

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.
