Embodiment 1

[0022]

[0023] Preparation:

[0024] (1) Preparation of bedaquiline solid composition:

[0025] (i) fumaric acid and hypromellose were added to 220mL of ethanol aqueous solution containing 80% ethanol and dissolved to make a mixed solution;

[0026] (ii) In the bedaquiline fumarate of 38 μm in the particle diameter d0.9 placed in the fluidized bed, spray the above-mentioned mixed solution, granulate, dry, and granulate to obtain the bedaquiline solid composition , wherein, the weight ratio of particles with a particle size smaller than 150 μm in the solid composition is 60% (w / w).

[0027] (2) Preparation of bedaquiline preparation:

[0028] The bedaquiline pharmaceutical preparation is obtained by mixing the above-mentioned bedaquiline solid composition with lactose, sodium carboxymethyl starch and magnesium stearate and pressing into tablets.

Embodiment 2

[0030]

[0031] Preparation:

Description

technical field [0001] The invention relates to a pharmaceutical preparation for treating pulmonary tuberculosis, specifically bedaquiline pharmaceutical preparation, and a preparation method of the pharmaceutical preparation. Background technique [0002] Bedaquiline Fumarate (Bedaquiline Fumarate) is a new type of drug for the treatment of multidrug-resistant tuberculosis developed by Janssen Pharmaceuticals, a subsidiary of Johnson & Johnson. In December 2012, FDA approved bedaquiline fumarate tablets to be launched in the United States. At present, the drug has been marketed in many countries around the world, including the United States, Europe, and Japan. In November 2016, the National Medical Products Administration (NMPA) approved the import and marketing of bedaquiline fumarate tablets in my country. The drug is a diarylquinoline anti-mycobacterial drug. It is suitable for the treatment of adults (≥18 years old) with multidrug-resistant tuberculosis (MDR-TB), and t...
