Cocaine esterase prevents cocaine-induced toxicity and the ongoing intravenous self-administration of cocaine in rats.
Cocaine esterase (CocE) is a naturally occurring bacterial enzyme, is a very efficient protein catalyst for the hydrolysis of cocaine, and has previously been shown to protect rodents from the lethal effects of cocaine. The current studies were aimed at evaluating the capacity of a longer acting mutant form (CocE T172R/G173Q; DM CocE) of CocE to protect against the lethal effects of cocaine, an...
متن کاملDisposition of cocaine and its metabolites in human sweat after controlled cocaine administration.
BACKGROUND Sweat testing is a noninvasive technique for monitoring drug exposure in treatment, criminal justice, and employment settings. METHODS We evaluated cocaine excretion in 9 participants' sweat after they received 3 low doses (75 mg/70 kg) of cocaine HCl subcutaneously within 1 week and, 3 weeks later, 3 high doses (150 mg/70 kg). Six additional participants completed portions of the ...
متن کاملCocaine, nicotine, caffeine, and metabolite plasma concentrations in neonates.
The objective of this study was to measure the umbilical cord plasma levels of cocaine, nicotine, caffeine, and their metabolites. Thirty-six neonates at risk for prenatal cocaine exposure were prospectively enrolled. Umbilical cord plasma was analyzed by gas chromatography-mass spectroscopy for cocaine, cocaethylene, benzoylecgonine (BZE), nicotine, cotinine, and caffeine. Eighteen neonates we...
متن کاملCorrelation of saliva cocaine levels with plasma levels and with pharmacologic effects after intravenous cocaine administration in human subjects.
The behavioral and physiologic effects of single, intravenous bolus doses of cocaine in 5 male human subjects were correlated with cocaine levels in saliva and blood. All measures were performed under double-blind conditions. Two test doses of cocaine (15 mg and 40 mg) and one placebo test dose were administered to each subject in a random, cross-over design. Each test day was separated by a mi...
متن کاملIntravenous self-administration of morphine and cocaine: a comparative study.
The aim of the present study was to estimate differences between patterns of morphine and cocaine use in Sprague-Dawley rats. This was done by first developing a set of conditions under which both drugs would be consistently self-administered over time. Subsequently rats were studied in groups of three, with only one rat actively self-administering morphine or cocaine while others two receiving...
