“The pronounced rate-decreasing effect of spiperone was attenuated by cocaine in a dose-dependent manner, but not by nisoxetine or quipazine.(ABSTRACT TRUNCATED AT 250 WORDS)”
“When the effects of cocaine were redetermined 3 days after spiperone or 1 day after raclopride administration was terminated, there was a parallel leftward shift in the dose-effect curve, indicating enhanced sensitivity to cocaine.”

“The concurrent administration of the D1 DA antagonist, SCH-23390, or the D2 DA antagonist, spiperone , to the subchronic regimen of cocaine also blocked the cocaine-induced increase in DYN levels.”

“ Cocaine (300 nM-30 microM) caused a concentration-dependent hyperpolarization of the membrane potential, with a maximum effect … +/- 2.2 mV (N = 6) and an EC50 of 4.2 microM. This action was antagonized by spiperone (1 microM), suggesting that the hyperpolarization was … through endogenous 5-hydroxytryptamine (5-HT).”

“Intravenous self-administration of cocaine is blocked by intracerebral microinjection of spiroperidol into the nucleus accumbens but not into the caudate nucleus.”
