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.

Robert Werdehausen et al.
Anesthesiology, 116(1), 147-158 (2011-12-03)
Lidocaine exerts antinociceptive effects when applied systemically. The mechanisms are not fully understood but glycinergic mechanisms might be involved. The synaptic glycine concentration is controlled by glycine transporters. Whereas neurons express two types of glycine transporters, astrocytes specifically express glycine

A fast liquid chromatography-tandem mass spectrometry with electrospray ionization method was developed and validated for simultaneous quantification of lidocaine and its active metabolite MEGX in 10 μL of plasma of neonates with seizures. The sample preparation consists of an easy

The dynamic liver function test based on the hepatic conversion of lidocaine to monoethylglycinexylidide (MEGX) can complement established static liver function tests if prognostic information is of particular interest. Because of its ease of use and rapid turnaround, the MEGX
