Comparison of physico-chemical characteristics of some articaine-containing anesthetics used in stomatology

Abstract

The article presents the results of the comparative determination of the quality of four articainecontaining anesthetics. The studies were conducted using high performance liquid chromatography (to determine the content of the active substance and impurities), nuclear magnetic resonance (for the determination of optical isomers (enantiomers)) and potentiometry (to adjust the pH of the drug solution). It was found that the studied drugs do not differ in the quantitative content of the active substance - articaine - and correspond to the requirements of the regulatory documents. The analysis showed the difference in the qualitative and quantitative content of the impurities. It was found that all the samples contained articaine as an equimolar mixture of R/S enantiomers. The pH of the aqueous solutions of the articaine-containing anesthetics varies from 3.37 to 3.96.
