How is the active metabolite of lisdexamfetamine dimesylate thought to affect dopamine and noradrenaline signalling in ADHD?

Dexamfetamine, the active metabolite of lisdexamfetamine dimesylate, is thought to block dopamine and noradrenaline reuptake into presynaptic neurons and increase their release into the extraneuronal space, although its therapeutic mechanism in ADHD is not fully established.
