Problems solved by technology

[0014] The present invention aims at the fact that fenofibrate is an insoluble drug with low solubility in water and is difficult to be absorbed by the body, resulting in poor bioavailability, and the traditional preparation method has many restrictions on the process and excipients, resulting in the problem that it is difficult to control the quality of the drug in production. Propose a kind of high dissolution rate fenofibrate tablet and preparation method thereof

Abstract

The invention discloses a high-dissolubility fenofibrate tablet and a preparation method thereof. The high-dissolubility fenofibrate tablet is prepared by coating a fenofibrate raw material with docosahexaenoic acid-beta-cyclodextrin, performing spray-drying and mixing and directly tabletting with auxiliary materials. By adopting the preparation method disclosed by the invention, the problems that by using a conventional method, the dissolubility is low and the bioavailability is poor as the mass of medicines is hard to control are solved; and compared with a conventional direct tabletting and wet-method pelleting process, the preparation method has the advantages that the dissolubility of medicines is effectively improved, the medicines are relatively good in dissolubility effect and the bioavailability is improved.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and relates to a solid oral preparation, in particular to a high-dissolution fenofibrate tablet and a preparation method thereof. Background technique [0002] Fenofibrate (Fenofibrate, FNB) is a clofibrate blood lipid regulator, its molecular formula is C20H21ClO4, its molecular weight is 360.84, its chemical name is 2-methyl-2-[4-(4-chlorobenzoyl)phenoxy Base] isopropyl propionate is a white or off-white crystalline powder, odorless and tasteless. It was first used clinically in 1975, mainly for the treatment of hyperlipidemia with unsatisfactory diet control therapy in adults. It is to reduce glycerol One of the first-choice drugs for triglycerides. Its effect of lowering triglycerides and mixed hyperlipidemia is more obvious than that of cholesterol. At the same time, it can also reduce blood uric acid levels. It also has a good effect on the treatment of type 2 diabetes and metabol...
