Abstract

The invention relates to the technical field of medicines, in particular to a gliclazide sustained-release capsule and a preparation process thereof. The content filled in the capsule is gliclazide micro-pills of which the surfaces are coated with sustained-release film coatings, and the gliclazide micro-pills are prepared from the following raw materials in portion by weight: 30 to 35 portions ofgliclazide, 30 to 50 portions of microcrystalline cellulose, 40 to 60 portions of lactose, and 30 to 70 portions of water. The sustained-release film coatings are prepared from the following raw materials in portion by weight: 5 to 20 portions of EudragitRS100, 10 to 40 portions of EudragitRL100, 10 to 40 portions of talc powder, and 1,000 portions of 95 percent ethanol solution. The method for preparing the gliclazide sustained-release capsule comprises the following steps: firstly, crushing the gliclazide; secondly, taking a proper amount of the gliclazide powder according to a gliclazide micro-pill formula to perform pelletizing so as to obtain the gliclazide micro-pills; and thirdly, coating the gliclazide micro-pills. The gliclazide sustained-release capsule can well control the in vivo release rate of the gliclazide and is safe and long-acting.

Description

(1) Technical field: [0001] The invention relates to the technical field of medicine, in particular to gliclazide sustained-release capsules and a preparation process thereof. (two) background technology: [0002] Diabetes mellitus is an endocrine and metabolic disease caused by insufficient insulin secretion and decreased sensitivity of target cells to insulin, resulting in metabolic disorders of sugar, protein, fat, water, and electrolytes. Commonly used oral hypoglycemic drugs include sulfonylureas and biguanides, among which sulfonylureas are the earliest discovered and widely used hypoglycemic drugs, and Gliclazide is the most commonly used. Gliclazide is the second-generation sulfonylurea hypoglycemic drug, and is currently the largest-selling sulfonylurea hypoglycemic drug. colored crystals. Its chemical name is 1-(3-azabicyclo[3.3.0]octyl)-3-p-toluenesulfonylurea, molecular formula: C 15 h 21 N 3 o 3 S, the structural formula is: [0003] [0004] Gliclazid...
