Metabolite Identification
Common Name3-Hydroxymonoethylglycinexylidide
Description3-Hydroxymonoethylglycinexylidide, also known as 3-OH-megx, belongs to the class of organic compounds known as alpha amino acid amides. These are amide derivatives of alpha amino acids. Lidocaine is used topically to relieve itching, burning and pain from skin inflammations, injected as a dental anesthetic or as a local anesthetic for minor surgery. 3-Hydroxymonoethylglycinexylidide is a very strong basic compound (based on its pKa). 3-Hydroxymonoethylglycinexylidide is a metabolite of lidocaine. In humans, 3-hydroxymonoethylglycinexylidide is involved in lidocaine (local anaesthetic) metabolism pathway. Lidocaine, Xylocaine, or lignocaine is a common local anesthetic and antiarrhythmic drug.
