Abstract

The invention discloses a posaconazole liquid suspension and a preparation method thereof. The raw materials are posaconazole, a microcrystalline cellulose-carboxymethylcellulose sodium compound, a nonionic surfactant, a buffer solution, dimeticone, sodium benzoate, titanium dioxide, high fructose syrup and a pharmaceutically acceptable liquid carrier; and wherein the pharmaceutically acceptable liquid carrier is purified water and glycerin. The posaconazole liquid suspension has the advantages of high stability, good reappearance between batches, and difficult settlement, and the preparation method has the advantages of simple process and easy industrialization.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a posaconazole liquid suspension and a preparation method thereof. Background technique [0002] Posaconazole, chemical name 4-[4-[4-[4-[[(3R,5R)-5-(2,4-difluorophenyl)-5-(1,2,4-triazole -1-ylmethyl)oxolan-3-yl]methoxy]phenyl]piperazin-1-yl]phenyl]-2-[(2S,3S)-2-hydroxypentan-3- Base]-1,2,4-triazol-3-one, whose structural formula is shown in formula I, is a drug for the prevention or treatment of fungal infections, a broad-spectrum antifungal drug developed by Schering-Plough, and its trade name is Noxafi. It was launched in Germany for the first time in December 2005, and was launched in the United States and the United Kingdom in 2006. So far, it has been listed in more than 60 countries or regions around the world. [0003] [0004] Posaconazole is indicated for the treatment of a variety of invasive fungal infections in adults who are intolerant or refractory to amphoter...
