METHOD FOR SUPPRESSING DECREASE IN VISCOSITY OF AQUEOUS LIQUID AGENT Russian patent published in 2016 - IPC A61K31/436 A61K31/728 A61K9/08 A61K47/18 

FIELD: pharmaceutics.

SUBSTANCE: invention relates to pharmaceutical industry, means for suppressing decrease over time in the viscosity of an aqueous liquid agent, which contains hyaluronic acid or a pharmaceutically acceptable salt thereof, and this method is characterized by blending pranoprofen or a pharmaceutically acceptable salt thereof into the aqueous liquid agent, where concentration of hyaluronic acid or a pharmaceutically acceptable salt in the aqueous solution is 0.001~1.0 % and where addition of pranoprofena or its pharmaceutically acceptable salt is performed so, that concentration of hyaluronic acid or a pharmaceutically acceptable salt in the aqueous solution is 0.001~1.0 %.

EFFECT: invention ensures maintenance of stable viscosity liquid aqueous agent, which contains hyaluronic acid or a pharmaceutically acceptable salt thereof, due to suppression of reducing viscosity for a long time.
