Abstract

The invention provides a compound preparation consisting of calcium rosuvastatin and a fenofibric acid choline salt time-selecting osmotic pump controlled release tablet and a preparation method thereof. The compound preparation structurally comprises the following components from inside to outside in sequence: a tablet chip consisting of a medicine containing layer and a boosting layer, a controlled release coating for a medicine release hole, a calcium rosuvastatin quick release layer and a protective gastric soluble thin film coating. The preparation method comprises the following steps of: (1) preparing the medicine containing layer; (2) preparing the boosting layer; (3) pressing the tablet chip; (5) coating a control release coating; (6) punching the coating tablet; (6) coating the calcium rosuvastatin quick release layer; and (7) coating the protective gastric soluble thin film coating.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations. More specifically, the present invention relates to a time-selective osmotic pump controlled-release tablet of rosuvastatin calcium and fenofibric acid choline salt and a preparation method thereof. Background technique: [0002] In recent years, with the improvement of people's living conditions and changes in eating habits, the incidence of hypercholesterolemia and mixed dyslipidemia has gradually increased. Hypercholesterolemia and mixed blood lipid abnormalities are the main causes of atherosclerosis, which in turn cause cardiovascular and cerebrovascular diseases, including coronary heart disease, stroke, myocardial infarction, etc., which seriously endanger human health. Among various diseases, the morbidity and mortality of cardiovascular and cerebrovascular diseases rank first. [0003] In the blood lipid composition, cholesterol and triglyceride are the main causes of atheros...
