Embodiment Construction

[0034] The present invention is further described below.

[0035] Pour the film material onto a pre-sterilized glass plate coated with a layer of liquid paraffin, spread it flat to form a film, and dry it at 45°C to 55°C or dry it naturally to make a film, and it can be dried until it does not stick to hands.

[0036] The thickness of the compound double-layer sustained-release drug film made by the method of the present invention is about 2-3 millimeters, and the size of the small pieces divided into can be 6 millimeters square, and the size of the small pieces can also be determined as required.

[0037] In "Spread the film-forming material slurry prepared by the same method above on the above-mentioned drug film, the thickness of the film-forming material slurry and the drug film is approximately the same, and form a film after drying", "the film-forming material slurry prepared by the same method above "Membrane material slurry" refers to:

[0038] According to "making th...

Abstract

The invention provides a preparation method of a compound double-layer sustained release emulsion for treating diseases of oral mucosa made from the following raw materials: borneol, calculus bovis artifactus, tindazole tinidazole, dyclonine hydrochloride, Tween-80, glycerol, saccharin sodium, sodium carboxymethyl cellulose (CMC-Na), polyvinyl alcohol PVA17-18 etc. The compound double-layer sustained release emulsion has heat-cleaning and detoxifying, swelling-dispersing and ache-relieving, bacteria-resisting and inflammation-diminishing, putridity-impelling and tissue regeneration-promoting, ulcer face and lesion place-effectively protecting and curing functions, shortens course of the disease, overcomes deficiencies of single-layer emulsion of Chinese medicine or western medicine, is durable with obvious curative effect. When a double-layer emulsion is compared with a single-layer emulsion, medicine is released from a single layer in the single-layer emulsion and from double layers in the double-layer emulsion, thus medicine locally contacts the lesion places, the medicine flowing outside is decreased and foreign odour of medicine in oral cavity is decreased. The compound double-layer sustained release emulsion is made by combining advantages of Chinese medicine and western medicine which are rationally matched, has low dosage, direct effect, convenient use, quick effect, low side effect, determined and good curative effect.

Description

technical field [0001] The invention provides a preparation method of a sustained-release medicinal film, in particular a preparation method of a compound double-layer sustained-release medicinal film for treating oral mucosal diseases. Background technique [0002] Oral mucosal ulcer diseases are clinical frequently-occurring diseases, especially recurrent aphthous ulcer is the most common oral mucosal disease, and the prevalence rate is as high as about 20%. The disease recurs periodically, with obvious burning pain, which affects the patient's language, diet, and mood, and the burden of thought is heavy. Some patients have "cancer fear", which seriously affects the work, study and daily life of the patient. The etiology of the disease is complex, and there are obvious individual differences. There are many research reports on its pathogenic factors, but there is no unified conclusion yet. Since the etiology of recurrent aphthous ulcer is still unclear, although there ar...
