Tetracaine HCl Basic Information:
Pharmaceutical-Grade Anesthetic Purity HCl Powder, CAS 136-47-0: Tetracaine, Lidocaine
Lidocaine Hydrochloride undergoes rapid metabolism in the liver, with its metabolites and the unchanged drug predominantly excreted via the kidneys. The biotransformation process entails oxidative N-dealkylation, ring hydroxylation, amide bond cleavage, and conjugation. N-dealkylation, a primary biotransformation pathway, produces metabolites such as monoethylglycinexylidide and glycinexylidide. These metabolites exhibit pharmacological/toxicological actions akin to, though milder than, Lidocaine Hydrochloride. Around 90% of the administered Lidocaine Hydrochloride is excreted as various metabolites, with under 10% excreted unchanged. The major urinary metabolite is a conjugate of 4-hydroxy-2,6-dimethylaniline.
