Abstract

The invention relates to a composite gel film agent, which is characterized in that sodium carboxymethyl cellulose and other gels are compounded into film agent matrix. The composite gel film agent has the following advantages that the film agent has hemostasis function, has the function of inhibiting bacteria growth, is more stable, can slowly and durably release components of drug so as to improve curative effect, is convenient to use because the gel film agent can quickly absorb water (tissue fluid) in the anus, vagina or uterus, nasal cavity and auditory meatus to expand and dissolve to generate biological adhesion so that the gel film agent is adhered to the cavity and the film agent drug solution is not easy to flow out and a barrier does not need to be placed at the vagina or the anus due to no outflow, has no stimulation, can be biodegradable in vivo, has no residue or toxic and side effects, and is accepted more easily by a patient under the condition of enhancing curative effect.

Description

technical field [0001] The invention relates to a composite gel film capable of carrying multiple medicines, which is composed of sodium carboxymethyl cellulose and other gels. Background technique [0002] At present, there are two types of film-forming materials commonly used as drug carriers, natural and synthetic polymers. Natural ones include starch, dextrin, cellulose, gelatin, gum arabic, agar, alginic acid, etc.; synthetic polymers include cellulose derivatives, polyvinyl alcohol, polyvinylpyridine, etc. Due to the single composition, there are inevitably disadvantages such as insufficient strength and toughness, too high or too low viscosity, too fast or too slow decomposition, etc. [0003] Usually the used medicament of various medicines for external use is mostly the form of liquid medicine, tincture, ointment. Not only is it inconvenient to store and carry, but also the clothes are polluted and part of the medicament is lost due to the need to smear on the aff...
