Application

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

Biochem/physiol Actions

Lidocaine metabolite
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.

Lidocaine has cardiovascular and neurologic toxicity, which is dose-dependent. Due to CYP3A4-involved metabolism, lidocaine may be prone to drug-drug interactions. Given statins have the possibility of combination with lidocaine in the clinic, we established in vitro models to assess the
