The method for preparing the pharmaceutical composition for treating allergic rhinitis comprises the following steps of: extracting the periplaneta Americana extractive and the effective components of the ephedra, and mixing to prepare the medicine. The preparation method of the invention is simple, gives full play to the periplaneta Americana extractive, and effectively improves the healing effect of allergic rhinitis; and the pharmaceutical composition is a new medicament worth of promoting, is convenient to use and has little toxic and side-effect.

Description

Pharmaceutical composition of a kind of treatment of allergic rhinitis and preparation method thereof
Technical field
The present invention relates to medical technical field, be specifically related to pharmaceutical composition of a kind of treatment of allergic rhinitis and preparation method thereof.
Background technology
It is documented that periplaneta americana is the insecticide of volume maximum in the Blattidae, originates in South America, periplaneta americana is traditional Chinese crude drug, is used as medicine its property plug salty in the mouth with dry and bright adult, poisonous, acid is arranged, functions such as dissipating blood stasis, removing food stagnancy, detoxifcation, diuretic, detumescence are arranged; Curing mainly infantile malnutrition, tonsillitis, health enclosed mass, carbuncle skin ulcer swells and ache and Scolopendra, venom etc.
Along with science and technology constantly develops, after years of research and found that in recent years the periplaneta americana epidermis contains sclerotin and chitin, elements such as bromine, zinc, nickel, violent, potassium, calcium, titanium, chlorine, sulfur, silicon, aluminum, magnesium; Muscle hydrolysis 13 seed amino acids; Its alcohol extract has the obvious suppression effect to cancerous cell, and cardiovascular disease is had tangible curative effect.In addition, health storage vitamin B 1, B 2, nicotinic acid and ascorbic acid etc., lymph contain trehalose, trehalase, glycoprotein, inositol, protocatechuic acid Fructus Vitis viniferae glycoside etc.All contain ergothioneine, 1-methyl-2-pyridinium carboxylate, trigonelline, glycine, betanin, anus alkali, trimethylamine, adenine etc.Clinical main application has: treat infantile malnutrition, control the carbuncle pyogenic infections from tumour or sore, control the Scolopendra wound, control innominate toxic swelling, control the worm venom.But also have periplaneta americana and medical herbs compatibility auxiliary treatment colon cancer.American-cockroach-extract can be controlled hepatitis B, and extract A T-2 preparation can cure mainly primary hepatocarcinoma, cardiovascular disease etc.
Notification number is CN 100525781C, name is called " American-cockroach-extract; contain pharmaceutical composition of this extract and preparation method thereof " and publication number is CN1943600A, it is two with the American-cockroach-extract relevant patent documentations of applicant in application in 2006 that name is called " pharmaceutical composition and the new purposes thereof that contain periplaneta americana and ethanol extraction thereof ", it discloses the preparation method and the part medical usage of American-cockroach-extract, in recent years, along with the further research to American-cockroach-extract, American-cockroach-extract has obtained further development in purposes pharmaceutically.
Allergic rhinitis is allergic rhinitis (allergic rhintis) again, is the allergic disease of nasal membrane, and can causes multiple complications.Sickness rate has rising to warm up in recent years.Allergic rhinitis is morbidity easily in the winter time generally, and the branch of long-term property, seasonality is arranged.Seasonal allergic rhinitis then is the outbreak in season, how in spring, morbidity in autumn.Classical symptom is that nasal obstruction, rhinocnesmus, headache, paroxysmal sneeze are shown effect continuously, a large amount of water sample nasal mucus and olfactory disorder etc.Badly influence patient's the quality of life so that the health status of whole machine body, also have influence on patient's doings and physical work.For example the allergic rhinitis outbreak time is difficult to the work of concentrating one's energy, if attend a meeting or in other public arenas outbreaks, also can bring embarrassed sensation to the people.The expert points out that allergic rhinitis should be treated as early as possible, otherwise can cause allergic asthma.
The allergic rhinitis common method of treatment has: 1, avoid therapy; 2, pharmacotherapy; 3, intranasal spray; 4, nasal injection method; 5, electricity burns or cryotherapy; 6, laser therapy; 7, hyposensitization; 8, hands art; 9, traditional Chinese medical science intranasal point medicine method.
At present, doctor trained in Western medicine is many to the many employings of the treatment of allergic rhinitis with antihistamine drug for oral administration, the interim inhibition of corticosteroids medicine, as oral western medicine, oral hormone, externally used solution lotion, Emulsion, mud cream, oil preparation, ointment, Emulsion, liniment, tincture and plaster etc.The corticosteroids medicine is used in long-time or heavy dose of external, can addiction cause drug dependence, and modal is that sb.'s illness took a favorable turn after the medication, in case after the drug withdrawal, the agents area primary affection increases the weight of.After again with hormone, above-mentioned sb.'s illness took a favorable turn or disappearance; As drug withdrawal again, knock-on property is sent out again, and than more serious in the past.
In sum, existing medicine still has unsatisfactory part for treatment of allergic rhinitis.For this reason, the invention provides a kind of new pharmaceutical composition that is used for the treatment of allergic rhinitis.
Summary of the invention
The objective of the invention is to: overcome above-mentioned deficiency of the prior art, a kind of pharmaceutical composition and preparation method thereof of treatment of allergic rhinitis of effective raising cure rate is provided.
Purpose of the present invention is achieved through the following technical solutions: a kind of pharmaceutical composition of treatment of allergic rhinitis is provided, it is characterized in that: the main component of described pharmaceutical composition and mass parts thereof are such as shown in down: 1~2 part of American-cockroach-extract; 4~18 parts in Herba Ephedrae.
The proportioning of one of preferred version of the pharmaceutical composition of above-mentioned treatment of allergic rhinitis is: 1 part of American-cockroach-extract; 8 parts in Herba Ephedrae.

The pharmaceutical composition of treatment of allergic rhinitis provided by the present invention can be made various ways such as tablet, suppository, capsule, is beneficial to satisfy different patients' medication custom.
The clinical testing data of allergic rhinitis cure rate:
One, patient's classified data:
Allergic Rhinitis 99 examples meet diagnostic criteria.Be divided into treatment group and matched group at random, 52 examples are organized in treatment, male's 28 examples, women's 24 examples, 16~40 years old age; Matched group 47 examples, male's 24 examples, women's 23 examples, 16~40 years old age.Two groups of patient ages, sex and courses of disease are learned processing by statistics, and difference does not have the significance meaning, has comparability.
Two, Therapeutic Method:
The treatment group: get tablet according to drug prepared of the present invention, oral, once two, twice on the one.
Matched group: chlorphenamine, oral, once two, twice on the one.
Three, curative effect comparative result:
Table 1 is depicted as two groups of curative effects relatively, and wherein 52 examples are organized in treatment, cure 48 examples, and cure rate is 92.31%, and total effective rate is 100%; Matched group 47 examples are cured 35 examples, and cure rate is 74.47%, and total effective rate is 95.75%.Table 2 is depicted as two groups of 7 days curative effects relatively, treats in 7 days, and treatment group cure rate is 78.85%, and the matched group cure rate is 51.06%.This shows that treatment group curative effect obviously is better than matched group.(n number of delegates in table 1 and the table 2)
