Abstract

The present invention relates to one new kind of medicine composition containing levocetirizine (or its pharmaceutically acceptable salt) and pseudoepherine (or its pharmaceutically acceptable salt). The medicine composition is pressed into double layer including the first layer containing levocetirizine (or its pharmaceutically acceptable salt) in the amount for resisting allergy effectively and the second layer containing pseudoepherine (or its pharmaceutically acceptable salt) in the amount as effective decongestant for nose. The medicine composition is used in treating seasonal and perennial allergic rhinitis.

Description

technical field [0001] The invention relates to a double-layer sustained-release oral composition. One layer contains the non-sedating antihistamine levocetirizine (or a pharmaceutically acceptable salt thereof) and the other layer contains the nasal decongestant pseudoephedrine (or a pharmaceutically acceptable salt thereof). The one containing levocetirizine (or its pharmaceutically acceptable salt) is the immediate release layer, and the one containing pseudoephedrine (or its pharmaceutically acceptable salt) is the slow release layer. Background technique [0002] Levocetirizine (or its pharmaceutically acceptable salt) is first listed in Germany, and then listed in the United Kingdom, Belgium, France and other countries. Clinically used for the treatment of various allergic diseases caused by histamine, such as seasonal and perennial allergic rhinitis, EP058146, WO9406429, US5698558, etc. have described the antiallergic effects of levocetirizine. Levocetirizine has a ...
