Intermittent cocaine self-administration produces sensitization of stimulant effects at the dopamine transporter.
Previous literature investigating neurobiological adaptations following cocaine self-administration has shown that high, continuous levels of cocaine intake (long access; LgA) results in reduced potency of cocaine at the dopamine transporter (DAT), whereas an intermittent pattern of cocaine administration (intermittent access; IntA) results in sensitization of cocaine potency at the DAT. Here, ...

Despite intensive medication development efforts, no effective pharmacotherapy for cocaine abuse has demonstrated efficacy for long-term use. Given the obvious importance of the dopamine transporter in the addictive properties of cocaine, the development and use of compounds that target the dopamine transporter represents a reasonable approach for the pharmacological treatment of cocaine abuse....

متن کاملEffects of combined dopamine and serotonin transporter inhibitors on cocaine self-administration in rhesus monkeys.
Dopamine transporter (DAT) inhibitors may represent a promising class of drugs in the development of cocaine pharmacotherapies. In the present study, the effects of pretreatments with the selective DAT inhibitor 3beta-(4-chlorophenyl)tropane-2beta-[3-(4'-methylphenyl)isoxazol-5-yl] hydrochloride (RTI-336) (0.3-1.7 mg/kg) were characterized in rhesus monkeys trained to self-administer cocaine (0...
متن کاملLack of cocaine self-administration in mice expressing a cocaine-insensitive dopamine transporter.
Cocaine addiction is a worldwide public health problem for which there are no established treatments. The dopamine transporter (DAT) is suspected as the primary target mediating cocaine's abuse-related effects based on numerous pharmacological studies. However, in a previous study, DAT knockout mice were reported to self-administer cocaine, generating much debate regarding the importance of the...
