Abstract

The invention discloses an oral tablet containing gliclazide and colesevelam hydrochloride and a preparation method of the oral tablet. The oral tablet comprises a quick release layer and a slow release layer, wherein a layer of coating is arranged out the slow release layer; the quick release layer comprises the following components in parts by weight: colesevelam hydrochloride, a quick release layer filling agent, and a disintegrating agent; the slow release layer comprises the following components in parts by weight: gliclazide, a slow release layer filling agent, magnesium stearate, hydroxy propyl cellulose and povidone. The preparation method of the oral tablet comprises the following steps: A preparing the quick release layer: screening various components of the quick release layer, mixing evenly, directly tabletting powder, and prepressing or carrying out once compression molding; B preparing the slow release layer; C forming the tablet: wrapping the coating outside the slow release layer, and carrying out compression molding together with the quick release layer. Compared with the prior art, the oral tablet is capable of playing a synergistic effect of medicines, achieves relatively good effects, is applied to correction of metabolic syndrome of patients with diabetes, and is beneficial to reduction of hyperlipidemia long-term risk of the patients with diabetes.

Description

technical field [0001] The invention relates to the field of medicine, in particular to an oral tablet containing gliclazide and colesevelam hydrochloride and a preparation method thereof. Background technique [0002] Gliclazide biguanide hypoglycemic drugs can increase the concentration of insulin by stimulating pancreatic β cells, so as to achieve the purpose of hypoglycemic. Colesevelam hydrochloride, as a non-absorbable polymer lipid-lowering drug, can bind to bile acid in the intestine and significantly reduce the reabsorption of the latter, and the depletion of bile acid will increase the conversion of cholesterol into bile acid. Therefore, colesevelam hydrochloride can be used to reduce the concentration of cholesterol. It can reduce the concentration of low-density cholesterol (LDL-C) by 15%-18%, and increase the concentration of high-density lipoprotein (HDL-C) by 3%. [0003] At present, the medical field has not used colesevelam hydrochloride and gliclazide to p...
