Problems solved by technology

At present, the in vitro dissolution rate of ordinary tablets is only about 83% in 30 minutes, and its dissolution rate is relatively poor, which affects the efficacy of voglibose to varying degrees.
The absorption of the drug mainly depends on the dissolution rate of the drug. Although the existing tablet preparation technology disclosed i...

Abstract

The invention discloses a voglibose tablet capable of being quickly dissolved out and a preparation method of the voglibose tablet, and belongs to the technical field of pharmaceutical preparations. According to the voglibose tablet, firstly, a solid dispersion of voglibose and a carrier material is prepared by adopting a solvent method and a spray drying technology, and then the solid dispersion is uniformly mixed with a filling agent, a disintegrating agent and a lubricating agent and is directly tableted. According to the voglibose tablet prepared by the method, the dissolution rate and the content uniformity are improved, meanwhile, the quality is stable and controllable, and the voglibose tablet is suitable for industrial large-scale production.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a rapidly dissolving voglibose tablet and a preparation method thereof. Background technique [0002] Diabetes is a series of clinical syndromes caused by absolute or relative insufficiency of insulin in the body. The main clinical manifestations of diabetes are polydipsia, polyuria, polyphagia and weight loss, as well as high blood sugar and high urine sugar. Improper treatment can also cause many serious complications, such as cardiovascular disease, retinopathy, chronic renal failure, etc. . [0003] At present, the drugs on the market for the treatment of diabetes are mainly sulfonylureas, biguanides and α-glucosidase inhibitors. However, sulfonylureas are easy to cause persistent hypoglycemia, biguanides can cause severe gastrointestinal reactions and liver and kidney damage, while α-glucosidase inhibitors have fewer adverse reactions except...
