Problems solved by technology

In the prior art, the research on glucocorticoid drugs is relatively extensive. For example, Chinese patent document CN101273970A discloses a microemulsion for the nasal cavity of glucocorticoid anti-inflammatory drugs, which consists of an oil phase, an aqueous phase, an emulsifier and an emulsifying agent. It is a transparent or translucent, low-viscosity, isotropic uniform oil-water mixing system formed spontaneously in an appropriate proportion of the agent. It is also a kinetically and thermodynamically stable system. The purpose of its research is to overcome the physical instability of the water-suspension nasal spray problems, making the liquid medicine system more uniform and the dosage more accurate, but it does not consider the adverse reactions after use
In addition, the Chinese patent document CN108283621A discloses a nasal nano-preparation mometasone furoate liquid crystal gel nanoparticles, which has high drug encapsulation rate, sustained release time and improved absorption rate, without considering the effect of the added excipients on patients after use adverse reactions

The invention discloses a medicine for treating allergic rhinitis, which comprises 0.04%-0.08% mometasone furoate, 0.5%-0.8% glycerin, 1.5%-2.0% sesame oil, 0.1%-0.5% chloride Sodium, 0.5-1.5% mixture of carboxypropylcellulose, hydroxyethylmethylcellulose and microcrystalline cellulose, 2%-3% mixture of Tween 80 and lecithin, 0.05-0.1% peppermint oil, Appropriate amount of sodium citrate buffer, add water for injection to 100%. Experiments show that the medicament of the present invention can effectively treat allergic rhinitis and effectively reduce the incidence of adverse reactions.

Description

technical field [0001] The invention belongs to the field of pharmaceutical composition preparations, and in particular relates to a pharmaceutical composition for treating allergic rhinitis and a preparation method thereof. Background technique [0002] Allergic rhinitis (allergic rhinitis, AR), also known as allergic rhinitis, is an allergic disease of the nasal mucosa. It is characterized by increased nasal mucosal reactivity. Itching, some with hyposmia, nearly 40% of allergic rhinitis patients can be combined with bronchial asthma, and can also be accompanied by pulmonary symptoms such as wheezing, coughing, shortness of breath and chest tightness, which directly affect the quality of life, sleep quality and mood of patients And work efficiency, etc., bring a heavy mental and psychological burden to patients, affecting the normal life of patients. At present, patients with allergic rhinitis account for 20%-30% of the total population in the world. In recent years, the ...
