Abstract

The invention relates to a gliclazide sustained-release tablet which specifically comprises gliclazide, a skeleton material, a diluent and a pore-foaming agent, and the skeleton material is methacrylic acid copolymer. The gliclazide sustained release tablet provided by the invention has relatively stable dissolution and release properties, does not have a burst release phenomenon, and has a dissolution curve consistent with that of commercially available drugs; meanwhile, the gliclazide sustained release tablet disclosed by the invention has better quality stability, simple preparation process, low production cost and is suitable for industrial large-scale production.

Description

technical field [0001] The invention relates to a sustained-release tablet for treating diabetes, in particular to a sustained-release tablet of gliclazide, and a preparation method of the sustained-release tablet. Background technique [0002] Diabetes has become one of the five diseases with the highest morbidity and mortality in the world, especially in developing countries such as China and Africa. Once diabetes is not well controlled, it will cause complications, leading to failure and lesions in the kidneys, eyes, feet and other parts, and it cannot be cured. Commonly used oral hypoglycemic drugs include sulfonylureas and biguanides. Gliclazide is a commonly used sulfonylurea hypoglycemic drug. Gliclazide has a stronger effect, and its mechanism is to selectively act on Pancreatic β cells promote insulin secretion and increase insulin release after eating glucose, inhibiting glycogen production and output. It has hypoglycemic effect on adults with diabetes, and can r...
