Possible Interaction: Cocaine and Benzoylecgonine



Research Papers that Mention the Interaction

COC contamination with higher CE, BE or NCOC content produced significantly higher concentrations (P = 0.0001) of all analytes.
Journal of analytical toxicology  •  2012  |  View Paper
After a single injection of h2E2 (120 mg/kg) and cocaine hydrochloride (0.56 mg/kg), the concentration of cocaine and BE excreted into the urine of rats decreased by 92% and 91%, respectively, from vehicle controls.

In fact, benzoylecgonine can last in the body for a very long time (a few days) and, thus, is responsible for the long-term toxicity of cocaine and a commonly used marker for drug addiction diagnosis in pre-employment drug tests.
ACS chemical biology  •  2016  |  View Paper
These observations are consistent with an inhibition in vivo of esteratic metabolism of cocaine to benzoylecgonine , resulting in higher cocaine levels and metabolism through alternative pathways.

Concentrations (ng/mL) of cocaine (249.30) and BZE (137.90) were higher when both substances were detected together than when detected alone.

If hands were washed prior to giving a fingerprint, BZE was detected only after the administration of cocaine.

Conclusions—Both cocaine and metabolites benzoylecgonine and cocaethylene induced endothelial VWF secretion, possibly explaining thrombotic risk after cocaine ingestion.
Arteriosclerosis, thrombosis, and vascular biology  •  2013  |  View Paper
If both substances were found (mean COC concentration 0.836 mg/L) the concentration of BZE was significantly higher (mean 0.669 mg/L) compared to cases with a single detection of BE (mean 0.209 mg/L) (p=0.001).

Half lives of cocaine and BE were strongly correlated (Spearman rank rho=0.73; P<0.001).

Moreover, the unpredictable extraction rate of both analytes, along with the hydrolysis of cocaine into BE significantly affects tissue concentrations, thus complicating the interpretation of quantitative results.
