Problems solved by technology

[0003] Cetirizine hydrochloride tablets have been on the market for more than 30 years. The preparation process includes wet granulation, dry granulation and direct compression process (requires pretreatment of cetirizine hydrochloride), but the die corrosion has not been completely overcome in the production process. And sticky punching problems, while the process is cumbersome, the process quality is not easy to control

Abstract

The invention relates to the technical field of pharmacy, and discloses a cetirizine hydrochloride tablet and a preparation method thereof, the cetirizine hydrochloride tablet comprises cetirizine hydrochloride and porous silicon; the weight ratio of cetirizine hydrochloride to porous silicon is 1: (3-5); the cetirizine hydrochloride tablet also comprises microcrystalline cellulose, and the weight ratio of cetirizine hydrochloride to microcrystalline cellulose is 1: (2-6); the microcrystalline cellulose is one or a combination of microcrystalline cellulose 102 and microcrystalline cellulose 112. According to the invention, the production operation procedure is simplified, the addition of auxiliary materials is reduced, the process quality control difficulty is reduced, and industrial mass production is facilitated.

Description

technical field [0001] The invention relates to the technical field of pharmacy, in particular to a cetirizine hydrochloride tablet and a preparation method thereof. Background technique [0002] Cetirizine hydrochloride is an oral selective histamine H1 receptor antagonist. No obvious anticholinergic and anti-serotonin effects, less central inhibitory effect; used to treat allergy-related diseases, relieve the following symptoms: allergic rhinitis (including seasonal persistent allergic rhinitis and perennial persistent allergic rhinitis) and chronic idiopathic urticaria. The dosage form of this drug is mainly oral solid, and because it has a strong pungent smell, the dosage form is mainly tablets. [0003] Cetirizine hydrochloride tablets have been on the market for more than 30 years. The preparation process includes wet granulation, dry granulation and direct compression process (requires pretreatment of cetirizine hydrochloride), but the die corrosion has not been com...
