Storage method

This product should be sealed and stored in a cool, dry place.

Synthesis method

1. Chloroacetyl chloride method

2,6-Dimethylaniline undergoes chloroacetylation with chloroacetyl chloride, then condenses with diethylamine, and then acidifies to form a salt to obtain lidocaine.

2. Diethylaminoacetic acid methyl ester method

In the presence of sodium methoxide, 2,6-dimethylaniline and N,N-diethylaminoacetic acid methyl ester are condensed, It is then acidified to form a salt to obtain the product.

Purpose

Widely used for topical anesthesia, infiltration anesthesia, conduction anesthesia, and epidural anesthesia. It is also an important drug in the treatment of sudden arrhythmias.
