Cocaine/analogs & derivatives* Cocaine/urine; Cold Temperature; Drug Stability; Humans The excretion kinetics of cocaine (C) and its two major metabolites, benzoylecgonine (BZ) and ecgonine methyl ester (EME), were determined by collecting all urine for 30 h from 5 cocaine users (subjects C, D, E, F, and G) given bolus doses followed by exponential cocaine infusions that delivered doses of 253 (subject C), 444 (subjects D, E, and Cocaine, a naturally occurring alkaloid obtained from the South American shrub Erythroxylum coca, is rapidly metabolized by cholinesterases to ecgonine methyl ester and benzoylecgonine that are excreted in urine. Both immunoassay screening and GC/MS confirmation procedures target benzoylecgonine. In this study, 25 postmortem urine specimens testing positive, for cocaine and ecogonine methyl ester (EME) by full scan electron impact gas chromatography/mass spectrometry, were used to evaluate the stability of EME in refrigerated and frozen conditions. benzoylecgonine (BZE) and ecgonine methyl ester (EME) in human urine has been established.

Both compounds remain detectable 4-6 times longer than COC in urine and plasma. Studying the causative factors, which alter the pharmacological and toxicological effects of COC, is of sig- nificant clinical importance.

Pseudoecgonine methyl ester and ecgonine methyl ester are formed as artifacts from the effect of sodium bicarbonate and methanol in the injection port of a gas chromatograph.

A rapid, rugged, and highly specific assay for the quantitation of cocaine (COC) and especially its primary metabolites benzoylecgonine (BZE) and ecgonine methyl ester (EME) in human urine … Urine or plasma or serum is spiked with deuterated internal standards cocaine-d3, benzoylecgonine-d3, ecgonine methyl ester-d3, and cocaethylene-d3 and buffered with phosphate buffer. The drugs in the sample are extracted by cation-exchange solid phase extraction. In this study, 25 postmortem urine specimens testing positive, for cocaine and ecogonine methyl ester (EME) by full scan electron impact gas chromatography/mass spectrometry, were used to evaluate the stability of EME in refrigerated and frozen conditions. After an initial quantitation (t = 0), these specimens were split and stored at either 4 degrees C or -20 degrees C.

The two major urinary metabolites of cocaine are benzoylecgonine (BE) and ecgonine methyl ester (EME). The major advantage of BE screening is that many commercial immunoassays are designed to detect BE. On the other hand, EME is more amenable to gas chromatographic screening. Ecgonine is suggested to be a promising marker of cocaine (COC) ingestion. A combined mass spectrometry (MS) and tandem MS (MS/MS) method was developed to simultaneously determine ecgonine and seven other metabolites of cocaine in human urine and whole blood with ultra-high-pressure liquid chromatography coupled with quadrupole time-of-flight mass spectrometry.
