Polymer derivative of -diethylaminoethyl ester of p-aminobenzoic acid with celluloseglycolic acid, method of producing and application thereof

摘要

A novel substance, viz., the salt of &bgr;-diethylaminoethyl p- aminobenzoate with celluloseglycolic acid has the following general formula: ##STR1## WHERE X STANDS FOR THE DEGREE OF SUBSTITUTION RANGING FROM 75 TO 100PPN STANDS FOR THE DEGREE OF POLYMERIZATION RANGING FROM 30 TO 120.PPA method of producing said compound comprises reacting &bgr;-diethylaminoethyl p-aminobenzoate with celluloseglycolic acid in an aqueous medium, whereupon the final product is isolated.PP The aforementioned compound, viz., the salt of &bgr;-diethylaminoethyl p-aminobenzoate with celluloseglycolic acid is the active principle of a local anesthetic drug. The proposed drug finds application in medical practive as an anesthetic in infiltration, conduction or spinal anesthesia, as well as in surface anesthesia.
