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.

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.

LP28530-1 Ecgonine methyl ester Ecgonine methyl ester (EME) is a major metabolite of cocaine, a wide spread illicit drug of abuse. [PMID: 7876811] Source: Regenstrief LOINC, PMID: 7876811. Fully-Specified Name Component Ecgonine methyl ester Property PrThr Time Visit Copyright Clearance Center. Abstract. The two major urinary metabolites of cocaine are benzoylecgonine (BE) and ecgonine methyl ester (EME).

Using this method, sample preparation consisted of a … Cocaine and its metabolites have also been detected in sweat. In contrast to urine, sweat primarily contains the parent drug, cocaine, and ecgonine methyl ester in much higher concentrations as compared to benzoylecgonine [81,82]. Kacinko et al.

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.

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.
