Mechanism of action

PDE10A is predominantly expressed in medium spiny neurons of the striatum and is involved in dopamine and glutamate signaling. By inhibiting PDE10A, E3810 enhances cAMP and cGMP signaling, which modulates neuronal activity and may restore balance in dysregulated neural circuits. This mechanism is hypothesized to be beneficial in neuropsychiatric and neurodegenerative conditions.
