However, the micropellet process requires fluidized bed bottom spray coating technology, multiple coatings on the micropellets, long processing time, the prepared suspension is not conducive to patients taking, and the dosage is not easy to control
[0007] None of the above information mentions fenofibric acid and its physiologically acceptable salt common tablet and its preparation method
Although the dissolution rate can be improved by using wet granulation process, the related substances are relatively high

Description
technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to a pharmaceutical composition containing fenofibric acid and a preparation method of tablets thereof. Background technique [0002] Fenofibric acid (English name FenofibricAcid), its chemical name is: 2-[4-(4-chlorobenzoyl)phenoxy]-2-methylpropionic acid. Molecular formula: C 17 h 15 ClO 4 , molecular weight: 318.75, its structural formula is as follows: [0003] [0004] Fenofibric acid is a second-generation phenoxyaromatic acid drug used to treat hypercholesterolemia and hypertriglyceridemia. It is the metabolite and active ingredient of fenofibrate in the human body. Therefore, it has better bioavailability than fenofibrate, and the bioavailability is not affected by food. [0005] Chinese patent CN102172347A discloses a preparation process of fenofibric acid enteric-coated sustained-release capsules. By granulating and pressing tablets to form microtable...
