Mechanism of action

Atomoxetine selectively inhibits the norepinephrine transporter, increasing norepinephrine availability in the prefrontal cortex and improving attention and executive function. OROS methylphenidate is a long-acting formulation that blocks dopamine and norepinephrine reuptake, providing sustained symptom control throughout the day. The combination targets complementary pathways to enhance attention and reduce impulsivity and hyperactivity.
