Description
Technical field:
The present invention relates to the pharmaceutical composition and the application thereof of a kind of people of being used for the treatment of or mammal oral ulcer, relate in particular to a kind of oral cavity sticking tablet
Background technology:
Oral ulcer also is recurrent aphtha, is commonly called as aphtha, is a kind of common oral mucosa membrane disease.Recurrent oral ulceration refers to that specially a class is agnogenio, repeatedly outbreak but self limiting, isolated that produce, circular or oval-shaped ulcer are arranged.Be recurrent aphtha (aphtha is the meaning of Greek " scorching hot and ulcer ") or recurrent aphtha etc. again.Size, the depth and number difference according to the ulcer performance can be divided into three types again clinically: the light-duty oral ulcer of recurrent, recurrent stomatitis ulcer and mikulicz's ulcer.
Recurrent oral ulceration is one of modal disease in the diseases of oral mucosa, among people's all one's life, oral ulcer does not take place almost, just has the people to take place once in a while, has the people frequently to show effect; And about people of about 20% suffers from oral ulcer in various degree, and child, between twenty and fifty people and old people can be taken place, and it is fallen ill and does not have obvious relation season.Oral ulcer can betide any position of oral mucosa, and pinhead-sized dots in red appears in pathological changes initial stage mucous hyperemia, rubescent, edema, and the scorching hot discomfort of local sense has violent spontaneous pain; Stimulation such as hot and cold, sour, sweet all makes pain increase the weight of, and can show effect repeatedly.Though oral ulcer be oral disease, can spontaneous recovery because morbidity is frequent, the state of an illness increases the weight of gradually, brings and have a strong impact on for people's work, life.Recurrent oral ulceration cause of disease complexity is still not really clear and definite so far.Modern medicine is then thought: the variation of viral infection, bacterial infection, digestive system disease and dysfunction, hormonal change, spiritual neural factor, inherited genetic factors, immunologic function, and lack trace element zinc, ferrum, folic acid, vitamin B2, B6, B12 etc. in other factors such as the human body and can cause oral ulcer.
The present external used medicine of treatment oral ulcer, it is a variety of to comprise that Chinese medicine and western medicine has, the Chinese medicine class have with Borneolum Syntheticum, Indigo Naturalis, etc. be XILEI SAN, BINGPENG SAN, the pearl Huang of the main component infantile malnutrition powder such as loose that disappears, but this dosage form inconvenience when using is scattered and disappeared very soon behind the coating with saliva.Western medicine has gargarism, ointment, reaches the membrane of some medicines etc., main active component is the glucocorticoid that has based on dexamethasone, dexamethasone acetate, based on the antibiotic of metronidazole etc., based on the vitamin medicaments of vitamin B group, with lidocaine hydrochloride, tetracaine hydrochloride local anesthetic of representative etc.Wherein, most widely used with the Therapeutic Method of topical application glucocorticoid again.Disclose a kind of dexamethasone acetate plaster and preparation method thereof (i.e. " meaning can be pasted ", Shenzhen Mrs's Pharmaceutical is produced) as Chinese patent CN00132507.3, formed by a kind of adhered layer and a kind of fluid-tight protective layer of pastille.Dexamethasone acetate can play antiphlogistic effect, can promote ulcer surface to shrink, and quickens ulcer healing, yet because glucocorticoid has side effect, even topical application also is easy to generate systemic side effects when life-time service, i.e. the inhibition of hypothalamus-hypophysis-adrenal gland (HPA) axle.And used the plasticizer of harmful dioctyl phthalate as protective layer according to the described stickup tablet of this patent; each sticking tablet contains dioctyl phthalate up to 0.8mg; though this phthalic ester plasticizer acute toxicity is very little; yet; studies show that phthalic ester plasticizer exists very big chronic toxicity to human health; even zooscopy result both domestic and external shows the low dosage phthalic ester plasticizer, also can be to the nerve of animal, reproductive system especially male reproductive system toxigenicity.And from January 16th, 2007, European Union also implemented in EU countries about the instruction (2005/84/EC number instruction) of restriction toy and child care products phthalate (ester) content.According to this instruction, for toy and child care products, the content of phthalate (ester) all must not surpass 0.1%, and the potential hazard of the plasticizer of phthalate to the health existence is described thus from the side.Yet, open that upright superfine (plasticizer is preferred in the osmosis type acrylic resin coated slow release film, Acta Pharmaceutica Sinica, 2001,36 (12): 937-941) reported because the water-insoluble physical property of plasticizer of phthalate ideal plasticizer when being considered in the prior art prepare the waterproof coating.
At present the nontoxic plasticizer of generally acknowledging mainly contains just own ester etc. of citric acid ester plasticizer, epoxy soybean oil, trimellitic acid esters plasticizer, tetraoctyl 1,2,4,5-benzenetetra-carboxylate, diethylene glycol dibenzoate, DOTP, decanedioic acid two, wherein is most widely used with citric acid ester plasticizer again.And above-mentioned several plasticizer is mainly used in the purposes such as packing of food and medicine in the prior art, and does not use it for the report of plasticizer in the medicine coating.
Momestasone furoate (CAS:83919-23-7, Mometasone Furoate) is a kind of new external, the nonfluorinated class of the development and production of U.S. Schering Plough company, but contain " potent " glucocorticoid hormone preparation of halogen, at first went on the market in the U.S. in 1987.It has the chlorine atom on 9 and 21 of corticosteroid hormone structure, on 17 (2 ') position a furoate (also can be described as heterocycle) is arranged.Its chemical structural formula is: two chloro-11 β of 9 α-21-, 17 α-two hydroxy-16 alpha--methyl-pregnane-1,4-diene-3,20-diketone-17 (2 ') furoate.Be widely used in airway disorders such as treatment dermatosis, asthma, allergic rhinitis, main dosage form has 0.1% momestasone furoate emulsifiable paste (trade name " Eloson ", Schering Plough production) and 0.05% and 0.1% nasal spray (trade name " nasonex, Schering Plough production).And momestasone furoate powder spray (trade name " Asmanex ", Schering Plough production).Yu Ruiyao (momestasone furoate pharmacological characteristics and treatment dermatosis clinical efficacy, 1999 the 8th the 8th phases of volume of Chinese Journal of New Drugs) reported that the effect celestone-V of momestasone furoate is strong 4～6 times, patient or healthy volunteer's in vivo test have been shown less inhibition hpa axis.
