RTI-113 administration reduces cocaine self-administration at high occupancy of dopamine transporter

RTI-113 [3beta-(4-chlorophenyl)tropan-2beta carboxylic acid phenyl ester hydrochloride], one of many phenyltropanes potent at and selective for DAT, inhibited self-administration of cocaine in rat at doses that did not alter responding maintained by food. The doses that inhibited cocaine intake produced significant levels of occupancy of DAT.
