Abstract

A slowly-or controllably-releasing semi-solid medicine for treating diabetes B is proportionally prepared from glipizide and slowly-releasing semi-solid skeleton carrier.

Description

technical field [0001] The invention relates to a sustained and controlled release semi-solid matrix preparation composition containing glipizide. Background technique [0002] Glipizide, white, odorless and tasteless, insoluble in water and ethanol, pKa is 5.9. Its English name is Glipizide, and its chemical name is 1-cyclohexyl-3-{4-[2-(5-methylpyrazine-2-amide)-ethyl]benzenesulfonyl}urea. Its structural formula is as follows: [0003] [0004] Molecular formula: C 21 h 27 N 5 o 4 S, molecular weight: 445.54 [0005] Glipizide is a second-generation sulfonylurea oral hypoglycemic drug, which can promote the secretion of insulin by pancreatic β cells and enhance the effect of insulin on target tissues; it can also stimulate pancreatic α cells to inhibit glucagon secretion. Inhibit liver glycogen breakdown, promote muscle utilization and consumption of glucose. Clinically, it is mainly used for patients with mild to moderate non-insulin-dependent diabetes mellitus...
