Application

MEGX has been used in an approach to improve the yield of N-dealkylated lidocaine.

Biochem/physiol Actions

MEGX is generated by hepatic cytochrome P-450 system upon oxidative de-ethylation. Measurement of MEGX by immunoassay contributes to liver function test. MEGX possesses antiarrhythmic action and therefore extends lidocaine effect.
Monoethylglycinexylidide (MEGX) is an active metabolite of lidocaine.
