Problems solved by technology

[0004] Nateglinide is a poorly soluble drug. When capsules or tablets filled with the original drug of nateglinide are taken orally, satisfactory dissolution cannot be carried out due to poor disintegration, and as a result, the quick effect of nateglinide cannot be exerted. , the effect of lowering the blood sugar level in a short period of time, in order to bring into play the unique drug effect of nateglinide, it is necessary to make the drug release from only concentrated to realize vegetarianism, thus the present invention is proposed

Abstract

The invention relates to a compound nateglinide valsatan medicinal composition, which is a dual-layer tablet and comprises a first layer of nateglinide and a second layer of valsatan, wherein the first layer is delivered from a self-soluble tablet to be immediately released; and the second layer is released from a self-disintegration or corroded tablet matrix.

Description

technical field [0001] The invention relates to a compound nateglinide valsartan pharmaceutical composition, a double-layer tablet and a preparation method thereof. Background technique [0002] Nateglinide, Nateglinide, chemical name: N-(trans-4-isopropylcyclohexyl-1-formyl)-D-phenylalanine, this product is a derivative of D-phenylalanine, It belongs to non-sulfonylurea hypoglycemic drugs, and its mechanism of action is mainly to block the opening of ATP-sensitive potassium channels in islet cells by binding to sulfonylurea receptors on islet B cells, resulting in depolarization of the cell membrane and opening of calcium channels. Promote insulin secretion. This product is a new type of mealtime blood sugar regulator, which can effectively control the postprandial blood sugar level. It has the characteristics of fast onset, short action time, low incidence of cardiovascular side effects and hypoglycemia. Oral absorption of this product is rapid. Healthy volunteers take 2...
