Abstract

The invention discloses a fexofenadine hydrochloride tablet and a preparation method thereof. The preparation is prepared from solid dispersion and pharmaceutical acceptable auxiliary materials by the procedures of evenly mixing and directly tabletting, wherein the solid dispersion is obtained by dissolving fexofenadine hydrochloride and citric acid into ethanol, drying and removing ethanol. According to the tablet disclosed by the invention, the dosage of a disintegrating agent is reduced under the premise of ensuring that the drug is rapidly dissolved out; the production cost is reduced; meanwhile, the fexofenadine hydrochloride tablet is simple in preparation technology, and good in surface after accelerated inspection.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to a fexofenadine hydrochloride tablet and a preparation method thereof. Background technique [0002] Fexofenadine hydrochloride is a second-generation H1 receptor antagonist, which can selectively block H1 receptors, has good antihistamine effect, has no anticholinergic and antiadrenaline effects, so it has no sedative effect and others It acts on the central nervous system and cannot pass through the blood-brain barrier. Fexofenadine hydrochloride can also inhibit the release of inflammatory substances from human nasal epithelial cells, and also inhibit the expression of ICAM-1 in epithelial cells. It is suitable for the treatment of seasonal allergic rhinitis, chronic idiopathic urticaria and other diseases. Its chemical name is α,α-dimethyl-4-[1-hydroxy-4-[4-(hydroxybenzhydryl)-1-piperidinyl]-butyl]-phenylacetic acid hydrochloride. At present, fexofenadine hydr...
