Problems solved by technology

However, the existing preparation process is still complicated. When preparing the drug, the applicant found that there is a serious sticking phenomenon in the tableting process, which is prone to separation and streaks, and the compression performance and stability need to be solved.
In addition, when fillers, disintegrants, and lubricants are used as excipients, they cannot interact well and achieve full effect, resulting in the addition of a large amount of excipients in order to improve the processing technology, thereby affecting the dissolution of the drug. and other properties, and in the preparation process and the use of organic solvents in the preparation process, there are risks of explosion and environmental pollution in actual production

Abstract

The invention relates to the technical field of pharmaceutical solid oral preparations and specifically relates to a cetirizine hydrochloride tablet and a preparation method thereof. The cetirizine hydrochloride tablet is prepared by using the following method: dissolving cetirizine hydrochloride into a povidone aqueous solution; then, carrying out wet granulation on cetirizine hydrochloride and microcrystalline cellulose to obtain a cetirizine hydrochloride pretreated particle; and finally, uniformly mixing and tabletting the cetirizine hydrochloride pretreated particle and pharmaceutically available auxiliary materials, wherein the weight ratio of cetirizine hydrochloride to the microcrystalline cellulose is 1:1 to 1:15.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical solid oral preparations, in particular to a cetirizine hydrochloride tablet and a preparation method thereof. Background technique [0002] Cetirizine hydrochloride is a second-generation H1 antihistamine, a long-acting and selective oral potent antiallergic drug. H1 receptor antagonists have good anti-allergic effects, and are often used for allergic rhinitis, allergic skin itching, conjunctivitis, etc. [0003] Currently, cetirizine hydrochloride is mainly in the form of tablets, which are highly acidic. Direct tableting or ordinary wet granulation is prone to sticking, and it is prone to esterification and degradation reactions with excipients under hot and humid conditions. [0004] Existing patents such as CN103340865A, CN104800178B, etc. disclose the preparation method of cetirizine hydrochloride tablets, which mainly avoids the direct contact of cetirizine hydrochloride with the ext...
