  The phenothiazines are antagonists at various dopamine receptors (D1 and D2) and at adrenergic and muscarinic receptors. They have a high affinity for D2 receptors, and the degree of binding with D2 receptors correlates with clinical potency in alleviating schizophrenia. Behavioral effects .

  Inhibition of dopamine release by acupuncture was completely prevented by SCH 50911 (101). GABAergic neurons are known to dampen dopamine neurons via inhibitory GABAB receptors in the mesolimbic dopamine system (102). Recently, the GABAB receptor agonist reduced reinforcing properties of ethanol (103).

  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.

  This mechanism was originally beneficial for humans, as it helped our ancestors relate pleasure to essential substances that they needed to live, like food and sex. The accumulation of dopamine in the brain makes it continue to create new dopamine receptors. Over time, the brain adapts and dopamine stops having the same effect as it did ...
