Mechanism of action

PDE10A is predominantly expressed in medium spiny neurons of the striatum. By inhibiting PDE10A, the drug increases cyclic nucleotide levels (cAMP and cGMP), enhancing downstream signaling pathways involved in motor control and cognitive function. This mechanism is being explored for neuropsychiatric and movement disorders where striatal dysfunction plays a role.
