Ezetimibe, simvastatin and nicotinic acid compound preparation and preparation method of ezetimibe, simvastatin and nicotinic acid compound preparation

The invention belongs to the field of pharmaceutical preparations and particularly relates to a compound preparation which takes ezetimibe, simvastatin and nicotinic acid as effective components and has the effects of reducing blood pressure and blood lipid and a preparation method of the compound preparation. The compound preparation is a sustained release tablet. Aiming at the problems of poor water solubility of the ezetimibe, unstability of the simvastatin to acid and oxygen, and the like, the preparation method of the compound preparation adopts a melt extrusion technology for improving the dissolution rate of the ezetimibe, and adopts a cladding membrane technology for enhancing the stability of the simvastatin in a body so as to give full play to the efficacy of all components of the compound preparation and have the best synergy effect. The specific process comprises the steps of preparing the nicotinic acid into a tablet core as a sustained release part, spraying an isolating layer on the tablet core, then spraying the simvastatin and the ezetimibe on an outer layer of the sustained release part as a quick release layer, and then carrying out film coating on the quick release layer. The compound preparation provided by the invention is mainly applied to the treatment or prevention of diseases and indications associated with heart and cerebral vessels.

Application of nicotinic acid in preparation of drug for relieving mammary gland fibrosis of dairy cows through GPR109A receptors

ActiveCN113564221AAlleviate fibrosis tendencyMitigation protectionOrganic active ingredientsCompound screeningDiseasePhysiology
The invention discloses an application of nicotinic acid in preparation of a drug for relieving mammary gland fibrosis of dairy cows through GPR109A receptors. The application comprises the following steps that S1, GPR109A receptor expression difference conditions are analyzed in mammary glands of normal dairy cows and fibrosis-prone dairy cows through in-vivo and in-vitro experiments, and it is determined that the GPR109A receptors are highly expressed in the mammary glands of the dairy cows with mammary gland fibrosis; and S2, fibrosis phenotypes in mammary epithelial cells of the dairy cows are detected, specifically, the change conditions of TGF-beta 1, alpha-SMA, Collagen2 and E-cadherin in the mammary epithelial cells of the dairy cows are specifically and correspondingly detected after the nicotinic acid is relieved. According to the application of nicotinic acid in preparation of the drug for relieving mammary gland fibrosis of the dairy cows through the GPR109A receptors, a brand-new relieving strategy for the mammary gland fibrosis tendency of the dairy cows is formulated, and the relieving effect of nicotinic acid on the mammary gland fibrosis tendency of the dairy cows is comprehensively evaluated by collecting normal mammary gland tissues and mammary gland fibrosis mammary gland tissues, separating primary mammary gland epithelial cells of the dairy cows and utilizing a molecular biology method. Nicotinic acid can effectively reduce rise of fibrosis phenotypes in mammary gland epithelial cells, so that the purpose of preventing the occurrence of mammary gland fibrosis diseases is achieved.
