چکیده انگلیسی
l-Stepholidine (l-SPD), an alkaloid extract of the Chinese herb Stephania intermedia, is the first compound known to exhibit mixed dopamine D1 receptor agonist/D2 antagonist properties and is a potential medication for the treatment of opiate addiction. The aim of the present study was to investigate the effects of pretreatment with l-SPD on heroin-seeking behavior induced by heroin priming. Male Sprague-Dawley rats were trained to self-administer heroin (0.05Â mg/kg per infusion) under a fixed ratio 1 schedule for 12 consecutive days and nose-poke responding was extinguished for 12 days, after which reinstatement of drug seeking was induced by heroin priming. Pretreatment with l-SPD (2.5, 5.0 and 10.0Â mg/kg, i.p.) inhibited the heroin-induced reinstatement of heroin-seeking behavior. Importantly, l-SPD did not affect locomotion, indicating that the observed effects of l-SPD on reinstatement are not the result of motor impairments. The present data suggested that l-SPD inhibits heroin-induced reinstatement and its potential for the treatment of heroin relapse.
