Chemically, benzoylecgonine is the benzoate ester of ecgonine. It is a primary metabolite of cocaine, [1] and is pharmacologically inactive. [2] It is the corresponding carboxylic acid of cocaine, its methyl ester. It is formed in the liver by the metabolism of cocaine by hydrolysis, catalysed by carboxylesterases, and subsequently excreted in ...
It is structurally similar to cocaine, which is the methyl ester of benzoylecgonine. Cocaethylene is formed by the liver when cocaine and ethanol coexist in the blood. [ 1 ] In 1885, cocaethylene was first synthesized (according to edition 13 of the Merck Index ), [ 2 ] and in 1979, cocaethylene's side effects were discovered.

A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test , are often grouped together into one test panel called a blood panel or blood work .
A drug test (also often toxicology screen or tox screen) is a technical analysis of a biological specimen, for example urine, hair, blood, breath, sweat, or oral fluid/saliva—to determine the presence or absence of specified parent drugs or their metabolites.
