How ONAPGO Works

ONAPGO is a non-ergoline dopamine agonist with high in vitro binding affinity for the dopamine D4 receptor and moderate affinity for the D2, D3, and D5 receptors, as well as adrenergic α1D, α2B, and α2C receptors. While the precise mechanism of action is unknown, it is believed to work by stimulating post-synaptic dopamine D2-type receptors within the caudate-putamen to address the symptoms of Parkinson's disease.
