Problems solved by technology

However, on the one hand, the micronization process has high requirements on equipment, and the producer needs a high investment. On the other hand, the micronization process also requires high levels of personnel operation. Static electricity is easily generated during the operation process, which poses a great safety hazard. Moreover, improper operation will easily lead to the phenomenon of rising impurities in raw materials due to frictional heat generation, resulting in a great waste of raw materials
In addition, in the preparation process of the glimepiride dispersible tablet in this patent application, the equal-volume incremental method is also used for material mixing, which is cumbersome to operate and not convenient for industrial production and application.

Abstract

The invention discloses a glimepiride dispersible tablet. After filling agent lactose contained in the prescription is screened by a 150-mesh sieve, micronization treatment does not need to be carried out to the basic remedy, glimepiride, the dissolution rate at the time of 15 minutes can reach above 90 percent, all indexes meet the medical standard, and the stability is good. The invention also discloses a preparation method of the dispersible tablet, which has no special requirement on equipment, and is simple in operation and suitable for industrial production and application.

Description

technical field [0001] The invention belongs to the technical field of medicine and relates to a pharmaceutical preparation and a preparation method thereof, in particular to a dispersible tablet of glimepiride and a preparation method thereof. Background technique [0002] Diabetes is a metabolic disorder that causes carbohydrate metabolism disorders due to hypofunction of pancreatic islets. Patients not only suffer from the disease itself, but also often suffer from its complications. According to relevant statistics, there are more than 80 acute or chronic complications caused by diabetes in the heart, brain, liver, lung, kidney, eyes, limbs, skin, nerves, etc., which seriously affect the daily life of patients and cause great pain to patients physically and mentally. . [0003] Glimepiride is a new third-generation sulfonylurea hypoglycemic drug, suitable for type Ⅱ diabetic patients whose blood sugar cannot be controlled by simple diet control and exercise. The drug p...
