Problems solved by technology

[0007] In order to solve the problem of release decline caused by membrane aging of choline fenofibrate film-controlled enteric-coated sustained-release pellets prepared by coating with water dispersion, the present invention provides a release that can always maintain a stable release rate within the validity period. High-performance membrane-controlled choline fenofibrate enteric-coated sustained-release pellets and capsules, which are characterized in that the core of the pellets contains low-substituted hydroxypropyl cellulose with high water-swellability, and the sustained-release coating is swollen by water absorption Membrane deformation, which counteracts membrane aging

Abstract

The invention relates to a choline fenofibrate film-controlled enteric slow-release pellet capsule. A slow-release film of the choline fenofibrate film-controlled enteric slow-release pellet utilizes Eurdragit RS 30D as a film-formation material. A pellet core of the choline fenofibrate film-controlled enteric slow-release pellet contains low-substituted hydroxypropyl cellulose having high expansibility, and also contains a pharmaceutically acceptable common excipient for the slow-release pellet, wherein preferably, the excipient comprises microcrystalline cellulose, and the pellet core comprises 10 to 40wt% of the low-substituted hydroxypropyl cellulose. The slow-release film comprises Eurdragit RS 30D, triethyl citrate as a plasticizer and talcum powder as an antiplastering aid, wherein preferably, a ratio of urdragit RS 30D to triethyl citrate to talcum powder is 30: 3: 4 and a film weight increasing ratio is in a range of 20 to 38%. The choline fenofibrate film-controlled enteric slow-release pellet comprises the pellet core containing low-substituted hydroxypropyl cellulose having high water expansibility and thus after absorbing water, the choline fenofibrate film-controlled enteric slow-release pellet expands so that the slow-release film is stretched; the thickness of the slow-release film is reduced; the water-permeable micropore size is increased; and permeability is improved and the permeability reduction caused by film aging is counteracted. Therefore, in middle and later stages, the choline fenofibrate film-controlled enteric slow-release pellet release rate is basically constant; in the last stage, residues are less; and stable release performances can be kept in the period of validity.

Description

technical field [0001] The invention relates to a choline fenofibrate membrane-controlled enteric-coated sustained-release pellet capsule, in particular to a choline fenofibrate membrane-controlled enteric-coated sustained-release capsule containing low-substituted hydroxypropyl cellulose The micropill capsule belongs to the field of pharmaceutical preparations. Background technique [0002] Choline fenofibrate is a lipid-lowering drug that degrades fat and triglycerides in plasma by activating peroxisome proliferator-activated receptor α (PPAR-α), activating lipolytic enzymes and reducing the synthesis of apolipoprotein CIII The clearance is significantly increased, thereby exerting a lipid-lowering effect. It is used in combination with statins to treat mixed dyslipidemia; single drug is used to treat severe hypertriglyceridemia, etc. The basic clinical requirement for this type of drug is that it can control symptoms for a long time. [0003] The solubility of choline ...
