Abstract

The invention discloses a levocetirizine dihydrochloride granule and preparation and detection methods thereof. The specification of the levocetirizine dihydrochloride particle is 2.5 mg, and milk sugar is used as filling agent. The levocetirizine dihydrochloride granule dispenses with the process of disintegration of tablets and capsules in a human body, the degree of dispersion in the human bodyis superior to the tablets and the capsules, and the absorption is faster than the tablets, the capsules and dispersible tablets; and the flowability, the dispersibility and the adhesiveness are better than the dispersible tablets, the granule is convenient to take, the mouthfeel is easier to adjust, and the curative effect of the medicine can be guaranteed to be better played.

Description

technical field [0001] The invention relates to a granule, in particular to a levocetirizine hydrochloride granule and a preparation method and a detection method thereof. Background technique [0002] Levocetirizine hydrochloride is a new generation of high-efficiency non-sedating antihistamines, which is the R-isomer of cetirizine hydrochloride. 1 The receptor affinity is twice that of cetirizine, which is highly selective for peripheral H 1 receptor antagonists. In January 2001, levocetirizine hydrochloride tablets were first listed in Germany, and then in the UK, for the treatment of seasonal and perennial allergic rhinitis caused by histamine, itchy eyes and skin, and chronic idiopathic urticaria. measles. At present, the solid preparations on the domestic market include levocetirizine hydrochloride tablets, levocetirizine hydrochloride capsules and levocetirizine hydrochloride dispersible tablets, with a specification of 5 mg. However, the listed formulations of le...
