Abstract

A desloratadine syrup preparation mainly comprises desloratadine, sucrose, a pH adjusting agent, a stabilizer, and a flavoring or antiseptic, wherein desloratadine exists in a hydrochloride form. The pH value of the syrup preparation is 4.0-7.0. The desloratadine syrup preparation has the advantages of fast effectiveness, strong effect, no toxicity to the heart, less drug interaction, and no food taboo.

Description

technical field [0001] The invention relates to a desloratadine syrup preparation and a preparation method thereof, belonging to syrup medicaments and a preparation method thereof. Background technique [0002] Desloratadine is a non-sedating long-acting histamine antagonist with potent and selective antagonism on peripheral H1 receptors. Literature reports have confirmed that desloratadine has the advantages of anti-allergic, antihistamine, and anti-inflammatory three-in-one; after oral administration, desloratadine is effectively excluded from the central nervous system (CNS), so it can be selected Sexually blocks peripheral histamine H1 receptors. A large number of in vitro (mainly human tissue cells) and in vivo studies have shown that this product has the advantages of rapid onset of action, strong potency, no cardiotoxicity, few drug interactions, and no food contraindications. [0003] The dosage forms of desloratadine clinical selection include tablet, dispersible ...
