Abstract

The invention discloses a Febuxostat capsule drug combination and a preparation method thereof. The Febuxostat capsule drug combination is characterized in that: ingredients for preparing 1000 capsules are as follows: 80-120g of Febuxostat, 120-180g of lactose (MeggleC80), 20-30g of microcrystalline cellulose (JRS12), 10-15g of croscarmellose sodium, and 1-1.5g of magnesium stearate. The invention also relates to the preparation method of the Febuxostat capsule drug combination, comprising the steps of: respectively drying the raw materials and the auxiliary materials at 80 DEG C for 3 hours, evenly mixing in equal proportion, and filling in capsules. The Febuxostat capsule prepared by the prescription and the preparation method provided by the invention has the advantages of good fluidity, good dissolution, small quality difference, high bioavailability, and good curative effect.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a pharmaceutical composition containing febuxostat as an active ingredient and a preparation method thereof. Background technique [0002] Febuxostat, its chemical name is: 2-(3-cyano-4-isobutoxyphenyl)-4-methyl-5-thiazolecarboxylic acid. Molecular formula: C16H16N2O3S, molecular weight: 316.37. Its structural formula is as follows: [0003] . [0004] Pharmacological type: a new generation of xanthine oxidase inhibitors. [0005] Mechanism of action: Febuxostat is a 2-arylthiazole derivative that achieves its therapeutic effect by selectively inhibiting oxidases by lowering serum uric acid levels. [0006] Indications: Febuxostat Tablets is a xanthine oxidase (XO) inhibitor for the long-term treatment of hyperuricemia in gout patients. It is not recommended to use febuxostat tablets for the treatment of asymptomatic hyperuricemia. [0007] Usage and d...
