[0036] Embodiment 1-11 preparation technology:

[0037] (a) Preparation of edoxaban solid dispersion: the weight component ratio of edoxaban tosylate, poloxamer and sodium lauryl sulfate is 1:1.5:0.5. Take edoxaban toluenesulfonate, add 10 times the amount of ethanol with a mass fraction of 80%, and ultrasonically assist in dissolving to obtain a homogeneous solution; take another poloxamer in an evaporating dish, heat it in a water bath, and pour it into toluene after it is completely melted Add edoxaban sulfonic acid solution, add sodium lauryl sulfate, stir evenly, evaporate the solvent, condense and stir the resulting mixture to solidify, dry, pulverize, and sieve;

[0038] (b) Preparation of the immediate-release layer: pass the edoxaban toluenesulfonate solid dispersion, the disintegrating agent and the filler in the prescribed amount through an 80-mesh sieve and mix uniformly, add magnesium stearate and mix uniformly to ob...

Abstract

The invention belongs to the technical field of drug sustained-release preparations, and in particular relates to a sustained-release preparation containing edoxaban and a preparation method thereof. The sustained-release preparation is composed of an immediate-release layer and a sustained-release layer, wherein the immediate-release layer is mainly composed of edoxaban solid dispersion, a disintegrant, a filler, and a lubricant; the sustained-release layer is mainly composed of edoxaban bulk drug, sustained-release release materials, fillers, lubricants and binders. The present invention provides an edoxaban-containing drug with excellent controlled release effect and high dissolution stability by optimizing the type and proportion of the filler, the sustained-release material, and the preparation method of the edoxaban solid dispersion in the optimized process. The sustained-release preparation solves the problems of poor release effect and low dissolution rate of the edoxaban sustained-release preparation.

Description

technical field [0001] The invention belongs to the technical field of drug sustained-release preparations, and in particular relates to a sustained-release preparation containing edoxaban and a preparation method thereof. Background technique [0002] Thrombosis has gradually become a common disease that threatens human health, especially in patients with cardiovascular and cerebrovascular thrombosis, its morbidity, disability and mortality are high. Thrombosis can cause stenosis and occlusion of the vascular lumen, leading to ischemia and infarction of major organs, thereby causing various diseases, such as myocardial infarction, ischemic cerebral infarction, and venous thromboembolism. [0003] The chemical name of Edoxaban is N-(5-chloro-2-pyridyl)-N'-[(1S,2R,4S)-4-[(dimethylamino)formyl]-2-[[4, 5,6,7-Tetrahydro-5-methylthiazolo[5,4-C]pyridin-2-yl)formyl]amino]cyclohexyl]oxalamide p-toluenesulfonate monohydrate, structural formula as follows: [0004] [0005] Edox...
