Problems solved by technology

[0010] However, this patent uses copovidone as a matrix polymer, but copovidone has a relatively high cost and narrow acquisition channels, which is not conducive to large-scale industrial production. At the same time, copovidone is not commonly used in preparations. The 2010 edition " The Chinese Pharmacopoeia is not included in the Pharmacopoeia, lacking certain security
Compared with copovidone, povidone not only has a wide source and low cost, and is included in the 2010 edition of "Chinese Pharmacopoeia", but there is a fatal defect in preparing solid dispersions with povidone as the matrix polymer, namely Under accelerated test conditions, the dissolution rate gradually decreases with time, and a specific crystal form appears. Table 12 and paragraph 0217 on page 28 of the patent CN102238945A disclose the defect of povidone, which affects the stability of olaparib preparations. It has caused an impact, which is not conducive to the preservation of the preparation

preparation example Construction

[0053] According to the preparation scheme of the present invention, those skilled in the art can choose the melt extrusion method, spray drying method and solvent evaporation method that have been matured in the art to prepare the olaparib solid dispersion, and can also be prepared according to the three methods described in the present invention. A kind of preparation scheme is prepared, and the method is as follows:

[0054] 1. Melt extrusion method

[0055] Take the prescribed amount of olaparib and povidone, add part of the lubricant, mix well, and put the mixture in a twin-screw extruder to extrude the mixture. During the extrusion process, apply a vacuum to the extrusion barrel to remove the melt The extrudate is calendered by passing it through two counter-rotating calender rolls, followed by cooling before grinding to obtain a solid dispersion.

[0056] 2. Spray drying method

[0057] Dissolve the Olaparib and povidone in the prescribed amount in an organic solvent ...

Abstract

The invention relates to the field of a pharmaceutical preparation, and in particular discloses an olaparib solid dispersion preparation and a preparation method thereof. The olaparib solid dispersion preparation consists of olaparib, povidone, a special lubricating agent, a special disintegrating agent and a thinner. According to the olaparib solid dispersion preparation disclosed by the invention, povidone, replacing the existing copovidone, is used as a matrix polymer, and appropriate auxiliary materials are added, so that the povidone, as the matrix polymer of the olaparib solid dispersion preparation, is wide in source, low in cost and clear in quality standard in accordance with Chinese Pharmacopoeia; meanwhile, the dissolution effect, bioavailability and stability of the preparation are guaranteed; and the industrial production of the olaparib solid dispersion preparation is facilitated.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to an olaparib solid dispersion preparation and a preparation method thereof. Background technique [0002] Olaparib, chemically known as 4-[3-(4-cyclopropanecarboxy-piperazine-1-carboxy)-4-fluoro-benzyl]-2H-phenazin-1-one, can be used to provide poly- ADP-ribose polymerase (PARP) inhibition. This effect can be used in the treatment of cancers, such as breast or ovarian cancer, which can be particularly effective in the treatment of cancers whose cells are defective in the homologous recombination (HR)-dependent DNA double bond break (DSB) repair pathway, such as BRCA1+ and / or BRCA2+ve cancer. [0003] 4-[3-(4-cyclopropanecarboxy-piperazine-1-carboxy)-4-fluoro-benzyl]-2H- Phenazin-1-one, which has the following structure: [0004] [0005] Olaparib is a drug with low solubility and low bioavailability. Ordinary preparations cannot improve the dissolution rate and b...
