Abstract

The invention discloses an oral preparation composition prepared by being matched with an alkaline compound taken as a stabilizing agent in cetirizine. The stability of an oral preparation added with the stabilizing agent is greatly improved.

Description

technical field [0001] The invention provides a pharmaceutical composition capable of improving the stability of cetirizine preparations, and relates to the technical field of improving the drug stability of cetirizine preparations. Background technique [0002] Cetirizine (cetirizine) is a long-acting peripheral histamine H1 receptor antagonist. Pharmacological experiments show that it has high pharmacological activity on allergic rhinitis, asthma caused by pollen, chronic urticaria and some other physical urticaria. At the same time, the penetration of the blood-brain barrier is reduced, and the side effects on the central nervous system are reduced. [0003] As reported in the literature "Research on the Interaction of Cetirizine Hydrochloride and Excipients" (Zhang Ziran, Jiang Lingtao. Huaxi Pharmaceutical Journal. 2002, 17(5): 394-395): due to the high chemical Activity, there are a variety of excipients that cannot tolerate their chemical activity under high tempera...
