Epinephrine in anaesthesia

drug delivery

ALEXYS Analyzer with DECADE Elite

 

A number of aneastetics such as bupivacaine, lidocaine, prilocaine and articaine use epinephrine as additive. It is a vasoconstrictor to retain the anestetic effect. Articaine in combination with epinephrine is used as an anesthetic for dental procedures in a number of European countries, US and Canada. Like other local anesthetic drugs, articaine causes a transient and completely reversible state of anesthesia (loss of sensation). The U.S. Pharmacopoeia monograph for Articaine Hydrochloride and Epinephrine injections describes a method for the analysis of the Epinephrine contents and organic impurity analysis. The ALEXYS Analyzer for Epinephrine in anesthetics is in compliance with all USP and EP requirements.
