摘要: Abstract Development of medications that attenuate symptoms nicotine withdrawal may be useful for facilitating smoking cessation. The neuropeptide oxytocin (OXY) decreases signs and other addiction-related effects several drugs abuse in animals, but has not been examined a preclinical model addiction. goal this study was to examine the OXY on rats, measured as increases somatic elevations intracranial self-stimulation (ICSS) thresholds (anhedonia-like behavior) during antagonist-precipitated from chronic infusion. Effects baseline ICSS non-dependent rats were also evaluated. (0.06 – 1.0 mg/kg, i.p.) blocked withdrawal-induced nicotine-dependent without affecting rats. In contrast, did affect thresholds. Relatively high doses (0.75 or 2.0 mg/kg) elevated These findings demonstrate blocks withdrawal. ability higher elevate reflect an aversive and/or motoric effect. data suggest OXY-based treating component syndrome, effective attenuating anhedonia.
