Problems solved by technology

Although chlorhexidine and its salt have good bactericidal effect at the concentration of 0.2% or more, because chlorhexidine and its salt water solution are not good, its aqueous solution stability is poor, and chlorhexidine and its salt often can be separated out when temperature lowers, Moreover, chlorhexidine and its salt are substances with a very bitter taste, and the concentration of 0.05% has a very bitter and unacceptable taste, which seriously affects the compliance of its use

Abstract

The invention relates to a chlorhexidine and oligochitosan-containing pharmaceutical composition, wherein the mass proportion of the chlorhexidine to oligochitosan is (0.1-1):1, the chlorhexidine comprises chlorhexidine acetate, chlorhexidine gluconate, chlorhexidine hydrochloride or chlorhexidine citrate, and the molecular weight of the oligochitosan is less than 5,000. The invention further relates to an application of the pharmaceutical composition in preparing a skin or object surface sanitizer, an application of the pharmaceutical composition in preparing an air-atomizing sanitizer, an application of the pharmaceutical composition in preparing an oral cavity sanitizer, an application of the pharmaceutical composition in preparing a vaginal irrigation solution, or an application of the pharmaceutical composition in preparing vaginal gels. According to the chlorhexidine and oligochitosan-containing pharmaceutical composition, the oligochitosan plays a role in obviously improving the antibacterial action of the chlorhexidine.

Description

technical field [0001] The invention relates to the field of medical products, specifically, the invention relates to a composition comprising chlorhexidine and chitosan oligosaccharide, and its application in disinfection and antibacterial, especially in daily health care. Background technique [0002] Chlorhexidine is a kind of surfactant, which has a fairly strong broad-spectrum antibacterial effect and is effective against a variety of bacteria. It has an antibacterial effect at a low concentration and a bactericidal effect at a high concentration. The commonly used salts of chlorhexidine are: : Acetate (chlorhexidine acetate), hydrochloride (chlorhexidine hydrochloride), citrate (chlorhexidine citrate), gluconate sugar salt (chlorhexidine gluconate). Although chlorhexidine and its salt have good bactericidal effect at the concentration of 0.2% or more, because chlorhexidine and its salt water solution are not good, its aqueous solution stability is poor, and chlorhexidi...
