reference example 1

[0042] Prescription (per 1000 bottles):

[0043] Mi Platinum

[0044] It can be prepared with reference to Chinese patent ZL02818527.7: take the prescribed amount of tert-butanol, add the prescribed amount of rice platinum, heat to 30-40 degrees, mix until the drug is completely dissolved, and adjust the water content of the solution under the monitoring of a Karl-Hugh moisture analyzer. To 1.5mg / mL, use a 0.22μm filter membrane to perform sterile filtration to obtain the intermediate of miplatin preparation.

Abstract

The present invention provides a miriplatin lyophilized preparation and a preparation method thereof, wherein the miriplatin lyophilized preparation adopts a tert butyl alcohol-ethanol-water ternary system during a preparation process, and the vacuum degree is controlled to more than 500 Pa during sublimation drying. According to the miriplatin lyophilized preparation of the present invention, the particle size distribution is uniform, and the number of the particles with the extreme small particle size is almost minimal while the number of the particles with the large particle size is less; with the preparation method of the miriplatin lyophilized preparation, the strictly limited waste content in the prior art is avoided, such that the preparation production is convenient, and the production cost is significantly reduced; and with the control of the vacuum degree during the freeze drying process, the eruption phenomenon is effectively eliminated, and it is ensured that the product with the good appearance quality is obtained.

Description

technical field [0001] The invention relates to a freeze-dried preparation of miplatin and a preparation method thereof, belonging to the field of pharmaceutical preparations. Background technique [0002] Miriplatin, the chemical name is (SP-4-2)-[(1R,2R)-1,2-cyclohexanediamine-N,N']bis(tetradecanoic acid-O)platinum, It is a new fat-soluble platinum anti-tumor drug developed by Sumitomo Corporation of Japan. Its monohydrate was approved for marketing in Japan in 2009. It is mainly used for the treatment of liver cancer clinically. Its structural formula is shown in formula Ⅰ: [0003] [0004] Metaplatin is soluble in chloroform and dichloromethane, slightly soluble in ethanol, and almost insoluble in water. Due to the extremely poor solubility of miplatin in water, it is technically difficult to develop lyophilized formulations. [0005] Studies have shown that suspending miplatin in iodized oil, a peripheral embolic agent, the formed miplatin-iodol can not only embol...
