Abstract

The invention relates to a medicine for treating allergic rhinitis. The medicine comprises the following raw materials according to parts by weight: 90-110 parts of fumarate rupatadine, 100-130 parts of pregelatinized starch, 30-50 parts of microcrystalline cellulose, 20-30 parts of hydroxypropyl methylcellulose solution of 3 percent, 3-6 parts of sodium carboxymethyl starch and 0.2-2 parts of magnesium stearate. The medicine has simple recipe, reasonable composition of the raw materials and proper proportion, and the dissolution degree is enhanced to more than 90 percent from 70 percent; and the effective components can be farthest absorbed by a human body, and a favorable therapeutic effect is achieved.

Description

(1) Technical field [0001] The invention relates to a medicine for treating allergic rhinitis and a preparation method thereof. (2) Background technology [0002] Allergic diseases are common and frequently-occurring diseases, especially allergic rhinitis. At present, the medicines for the clinical treatment of allergic rhinitis in my country mainly include antihistamines chlorpheniramine (chlorpheniramine), astemizole (astemizole), terfenadine (Mintel), cetirizine (Centirizine). Temin), loratadine (Kemineng), etc., there are relatively few varieties. Among them, chlorpheniramine has a strong sedative effect and can cause drowsiness and fatigue; astemizole and Mitel can cause severe cardiotoxicity. Cetirizine and loratadine have gradually occupied the market due to their low cardiotoxicity and few side effects, replacing chlorpheniramine, astemizole, and Mitel. However, antihistamines generally have the problems of large side effects and unsatisfactory curative effects. ...
