Abstract

The invention relates to a hydrochloric acid levocetirizine orally disintegrating tablet and a preparation method thereof. The hydrochloric acid levocetirizine orally disintegrating tablet is obtained by directly pressing principal medicine and accessories. The tablet of the invention can be dissolved fast in a mouth cavity and has no grit feeling and high biological availability, which takes effect fast and can have curative effect faster.

Description

technical field [0001] The invention provides a levocetirizine hydrochloride orally disintegrating tablet and a preparation method thereof, belonging to the technical field of pharmaceutical preparations. Background technique [0002] Levocetirizine non-sedating antihistamine, in 2001, levocetirizine hydrochloride tablets have been listed in Germany and the United Kingdom. Levocetirizine hydrochloride is mainly used for the treatment of seasonal and perennial allergic rhinitis, itchy eyes and skin, and chronic idiopathic urticaria caused by histamine. The affinity of the R-isomer of cetirizine hydrochloride to the H1-receptor (K1=3.2nmol / L) is twice that of cetirizine (K1=6.3nmol / L), which is a highly selective peripheral H1-receptor Body antagonist, is a drug with dual anti-allergic effects, its anti-allergic effect is stronger than other second-generation antihistamines, levocetirizine is one of the optical isomers of cetirizine hydrochloride (L-body ), is the active ing...
