Antipsychotic action: reduce hallucinations, delusions. Sedation: helps in agitated patients, but in not essential for antipsychotic activity. Decreased spontaneous activity. Mechanism of action: Dopamine receptor blockade in mesolimbic-mesocortical dopaminergic system. Inhibits adenylyl cyclase. Lowered seizure threshold

Mechanism of action/pharmacology Dopamine is an immediate catecholamine precursor of noradrenaline that directly stimulates alpha, beta and peripheral dopaminergic receptors in a dose-dependent manner, as well as acting indirectly by releasing endogenous noradrenaline from storage sites in sympathetic nerve endings.

While each drug has a different mechanism of action, each drug increases the activity of the reward pathway by increasing dopamine transmission. Because of the way our brains are designed, and because these drugs activate this particular brain pathway for reward, they have the ability to be abused.
