Abstract

The invention relates to a preparation for treating allergic rhinitis. The preparation is prepared by pressing a quick release layer and a sustained-release layer into bilayer tablets and coating, wherein the quick release layer consists of the following components in percentage by mass: 1 to 10 percent of levocetirizine hydrochloride, 1 to 15 percent of disintegrating agent, 0.5 to 3 percent of lubricating agent, 0 to 8 percent of adhesive and the balance of filler; the sustained-release layer consists of the following components in percentage by mass: 20 to 30 percent of pseudoephedrine hydrochloride, 50 to 60 percent of sustained-release framework material, 0.5 to 3 percent of lubricating agent, 0 to 8 percent of adhesive and the balance of filler; and the mass ratio of the levocetirizine hydrochloride to the pseudoephedrine hydrochloride is 1:48. The sustained-release tablets for treating the allergic rhinitis have bright and clean surfaces, and the release behavior of the main medicine pseudoephedrine hydrochloride of the sustained-release tablets has high consistency with that of American marketed medicine cetirizine hydrochloride and pseudoephedrine hydrochloride sustained-release tablets through detection; and the dissolution rate of the main medicine levocetirizine hydrochloride of the sustained-release tablets in 30 minutes is over 90 percent, so that the sustained-release preparation for treating the allergic rhinitis has high bioavailability, a good absorption effect, comprehensive and effective clinical curative effects, small side effects and ideal safety.

Description

technical field [0001] The invention relates to a medicine for treating rhinitis, in particular to a medicine preparation for treating allergic rhinitis and a preparation method thereof, belonging to the technical field of medicines. Background technique [0002] Histamine-mediated perennial or seasonal allergic rhinitis with symptoms including nasal congestion, sneezing, rhinorrhea, itchy nose, palate, and throat, itchy, watery, and red eyes, nasal pain, headache, loss of sense of smell, and Chronic pharyngitis, recurrent nasal cavity and sinus infections, etc., are conditions with a very high incidence. Epidemiological studies show that: 20%-30% of young people suffer from allergic rhinitis, and the incidence of allergic rhinitis among adults over 30 years old is about 2 / 3. Allergic rhinitis not only seriously affects the health and quality of life of patients, but also causes a heavy economic burden to families and society. The annual direct and indirect medical expenses...
