About

Parkinson's disease is a brain disorder that gradually damages nerve cells controlling movement and other body functions, causing tremors, stiffness, slowed movement, and balance problems, along with sleep, smell, mood, and thinking changes that worsen over time. Tavapadon is an oral drug that binds to D1 and D5 dopamine receptors in the brain and partially switches them on, mimicking dopamine's signal without fully overstimulating it. Because Parkinson's is tied to falling dopamine signaling, topping up that signal with tavapadon may help ease movement symptoms and could offer a steadier option for people whose symptoms fluctuate.
