ABSTRACT
The paper studies the kinetics of alkaline hydrolysis and stability under non-isothermal conditions of heptacainium chloride and carbisocainium chloride in the medium of aqueous-ethanolic solution of sodium hydroxide c = 0.1 mol/l and buffer solutions of values of pH 7.0 and pH 8.0. The results of the study of the kinetics of hydrolysis by means of a non-isothermal test - rate constants and activation energy values served as the basis for exact evaluation of the stability of these potential pharmaceuticals. The objective of the paper links up with the previous studies of these substances.
