It is clear that D1, D1 , and D5 receptors, and the dopamine transporter play an important role in the actions of psychostimulants, although developmental factors must be taken into account for the compensation or overcompensation levitra efficacy. Low doses of D1 antagonists appear in rodents almost as competitive antagonists to cocaine. For example, recent evidence suggests that the norepinephrine transporter mediates the self-administration of cocaine in dopamine transporter knockout mice (Carboni et al., 2000).
D1 antagonists block responding for cocaine but also have pronounced motor response inhibitory actions. Dopamine transporter knockout mice are dramatically hyperactive but also show a blunted response to psychostimulants levitra efficacy (Giros et al., 1996). D3 antagonists block drugseeking behavior associated with cocaine in secondorder and progressive-ratio schedules.
And in some cases supersensitivity to psychostimulants , d2 and D6 knockout mice show hyperactivity but no blunting of psychostimulant activity. In summary, pharmacological studies with selective D1 , D1 , and D4 antagonists and knockout studies have shown that all three receptor subtypes appear to mediate the reinforcing effects of cocaine, albeit possibly different components of the response.
