Abstract

The invention discloses a dissolution method of tablets containing (+)-1-(3-Ethoxy-4-methoxyphenyl)-2-(methylsulfonyl) ethylamine N-acetyl-L-leucine salt. According to the technical scheme, a lauryl sodium sulfate aqueous solution with the concentration being 0.1%-1.0% is used as dissolution media, the dissolution temperature is 37 DEG C, a paddle method is used by 50-75 r / min, ultraviolet spectrophotometry is adopted, and the absorption degree is determined at 230 nm. Through the method, the dissolution behavior and the preparation mass of a reaction preparation can be reflected objectively. Meanwhile, the invention discloses a preparation technology of the tablets. The preparation technology includes the steps of sieving, mixing, dry granulating, total blending, tabletting, coating and packaging for being put in storage. The sticking problem of the tablets and the problem of being poor in content uniformity in the production process can be well solved.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to a tablet dissolution test method with phosphodiesterase-4 (PDE-4) inhibitory effect. Background technique: [0002] Psoriasis, commonly known as psoriasis, is a chronic inflammatory skin disease with a long course of disease and a tendency to relapse, and some cases are almost unhealed throughout life. Psoriasis can be found all over the world, the highest prevalence in Europe is Denmark (2.9%) and the Faroe Islands (2.8%), and the average prevalence in Northern Europe is about 2%. The prevalence of psoriasis in the United States based on the demographic survey is between 2.2% and 2.6%, and there are about 150,000 newly diagnosed cases every year. The prevalence of psoriasis in Asia is low, with a prevalence of about 0.3% in demographic surveys. [0003] Apremilast is a small molecule phosphodiesterase 4 (PDE4) inhibitor that has specific effects on cyclic adenosi...
