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. To ascertain the merits …

The metabolism is dominated by hydrolytic ester cleavage, so the eliminated metabolites consist mostly of benzoylecgonine (BE), the major metabolite, and other significant metabolites in lesser amounts such as ecgonine methyl ester (EME) and ecgonine.

Cocaine hydrochloride is rapidly metabolized to two inactive metabolites called benzoylecgonine and ecgonine methyl ester.
