Problems solved by technology

[0005] At present, the clinically used sulfadiazine silver and sulfadiazine zinc preparations are mainly creams, ointments, powders, and suspensions that are currently prepared and used in clinical practice. These preparations have certain defects, such as: drug penetration Poor ability, insufficient wound moisturizing ability, strong irritation during administration, short duration of drug effect, difficult to control the dosage, excessive local drug may cause skin rash, dermatitis, muscle pain and even subtoxicity and many other problems

Abstract

The invention discloses a suspension preparation of temperature change painless nano sulfadiazine metallic compound hyaluronic acid. The formula comprises a sulfadiazine metallic compound, a hyaluronic acid substance, an analgetic, a dispersing agent aid, a suspension aid and water, wherein the sulfadiazine metallic compound comprises sulfadiazine silver and sulfadiazine zinc; the hyaluronic acid substance is sourced from biological fermentation and animal tissue extraction and the like and can be hyaluronic acid or hyaluronate or crosslinked hyaluronic acid or crosslinked hyaluronate; the analgetic comprises ropivacaine, bupivacaine, levobupivacaine, lidocaine and other local anesthetics or combination of the local anesthetics; the dispersing agent aid comprises chlorhexidine, Tween series, oleic acid or sodium oleate; the suspension aid can comprise glycerinum, celluloses, poloxamer series and hyaluronic acid substances. The suspension preparation is mainly used for burn, scald or the surface of a wound caused by explosion or anabrosis, has the main clinical characteristics that pain is rapidly relieved, the surface of the wound is subjected to rapid film formation and rapid healing of the wound is promoted, and the conventional main administration modes refer to spraying, smearing and coating.

Description

technical field [0001] The invention relates to a class of sulfadiazine metal compounds, especially the formulation of temperature-variable painless nanometer sulfadiazine silver or sulfadiazine zinc hyaluronic acid suspension preparation. The painless nanometer sulfadiazine metal compound hyaluronic acid suspension preparation is mainly used It is used for recovery treatment of open wounds caused by burns, scalds, explosions and mechanical injuries such as abrasions. Background technique [0002] Burns, scalds, explosions or mechanical injuries cause the skin surface to be damaged and lose its ability to protect tissues, creating convenient conditions for bacterial infection, and the exudation of a large amount of interstitial fluid provides a good environment for bacterial proliferation. If the treatment of the injured part is not timely, it will easily lead to a series of pathophysiological changes of the wound, making the injury more complicated and serious, thus increas...
