摘要

The present invention relates to a novel liquid composition comprised of piroxicam or its pharmaceutically acceptable salt (a non-steroid anti-inflammatory drug) and hyaluronic acid or its pharmaceutically acceptable salt (used for treatment of degenerative arthritis). Specifically, the invention provides a highly physicochemically stable liquid injection, comprising piroxicam and hyaluronic acid as active ingredients and &bgr;-cyclodextrin or its derivative and polyethylene glycol as additives to enhance its physicochemical stability, and the preparation method thereof. Therefore, the novel composition and the formulation method thereof provided by the present invention may be used to produce a liquid injection composition of piroxicam and hyaluronic acid.
