FIELD: medicine, pharmaceutics.
SUBSTANCE: group of inventions refers to medicine, particularly to ophthalmology. An aqueous liquid ophthalmic composition contains hyaluronic acid in the concentration of 0.05-0.4% or its pharmaceutically acceptable salt, and additionally contains gluconic acid and its salt with a metal, but does not contain chlorhexidine or its salt. A method for improving the viscosity stability of the aqueous eye-drop ophthalmic composition containing hyaluronic acid is conditioned by introducing gluconic acid and its salt with the metal.
EFFECT: invention provides slowed-down viscosity reduction of the aqueous ophthalmic composition.
