A kind of external preparation for the treatment of hemorrhoid
Technical field
The invention belongs to medical art, relate to a kind of pharmaceutical composition for the treatment of hemorrhoid, particularly relate to a kind of external preparation for the treatment of hemorrhoid.
Background technology
Hemorrhoid are a kind of common property, multiple characteristic of disease anal and intestinal disease, hemorrhoid are under rectum end mucosa and under anal canal skin, the soft vein agglomerate expanded and flexing is formed occurs venous plexus, main clinical manifestation for having blood in stool, pain, edema, falling inflation, pruritus, secretions increase and the symptom such as to deviate from, relevant research shows, the sickness rate of China's hemorrhoid is about 46%, reach 70% in some district, sickness rate that is American-European, Japan Data investigation is about 40%-60%.Having blood in stool, deviating from and the symptoms such as pain appears because of hemorrhoid in many patients, has had a strong impact on life, working and learning, so there is the exploitation of the hemorrhoid treating medicine of good result to have great importance.
The method of current treatment hemorrhoid mainly contains Drug therapy, surgical ligation and injection treatment.Anorectal educational circles of China has held the sick symposium of national hemorrhoid in April, 2000 in Chengdu, to explicitly pointing out in the new definition of hemorrhoid " objects of all treatments are not eliminate hemorrhoid bodies; but eliminate symptom; and the symptom removing hemorrhoid is more meaningful than change hemorrhoid body size, should be considered the standard of therapeutic effect ".These new treatment concept make the Therapeutic Principle of hemorrhoid clear, and the non-operative treatment importance that especially basic pharmaceutical is treated is appeared suddenly.Now mostly the suggestion of scholar be more than ninety percent hemorrhoid patients can adopt non-operative treatment, only need surgical intervention less than the hemorrhoid patients of 10%.Reason is Drug therapy energy reducing swelling and alleviating pain, relief of symptoms, turn avoid the pain of operation and the complication of injection treatment, so most people is applicable to Drug therapy.Medicine at present for hemorrhoid mainly contains antibiotics, hemorrhage and Chinese patent medicine, front two class medicines often take stopgap measures refractory this, recurrence probability is large, of long duration often can worsen.In addition, at present drug treatment takes for oral administration or topical patch to need systemic Absorption to treat relieving constipation medicine in addition clinically, this kind of drug main will rely on softening stool, the impact of stool to anus blood stasis is reduced during defecation, thus alleviate the misery of hemorrhoid patients, but the basic state of an illness that this kind of medicine does not change hemorrhoid patients does not change the cause of disease in other words conj.or perhaps, and in fact the state of an illness is under development.
