Abstract

The invention discloses an amplified production method of a Regadenoson injection. The method comprises the following steps: (1) preparing a 15%-35% by mass propylene glycol aqueous solution and heating the solution to 60-75 DEG C or adding propylene glycol into water for injection at 60-75 DEG C to be dissolved to prepare a 15%-35% by mass propylene glycol aqueous solution, then adding Regadenoson to be mixed and dissolved at 60-75 DEG C, then successively adding and dissolving disodium hydrogen phosphate, sodium dihydrogen phosphate and edetate disodium, mixing till disodium hydrogen phosphate, sodium dihydrogen phosphate and edetate disodium are fully dissolved, replenishing water for injection to a constant volume to obtain a medicine liquid; and (2) filtering and canning the prepared medicine liquid, and then sterilizing the medicine liquid to obtain the Regadenoson injection. The process disclosed by the invention solves the problem that the medicine liquid is exposed in a naked environment for a relatively long time. The medicine liquid with high quality is prepared according to a correct feeding sequence, the laboratory experiment is transferred to amplified production in a workshop, and the sterile level of the product is improved; the preparation process has the advantages of being mild in condition, simple and rapid to operate, low in cost, stable in property of medicine liquid, high in quality standard and suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of biomedicine, in particular to a preparation method of Regadeson injection and its enlarged production. Background technique [0002] Regadeson, also known as adenosine, trade name: LEXISCAN, common name for injection: REGADENOSON, molecular formula: C 15 H 18 N 8 O 5 ·H 2 O, molecular weight: 408.37, its structural formula is: [0003] [0004] Regadeson Injection was first launched in the United States by Astellas in 2008, and has grown by 100% every year since its launch, and has now reached a steady annual sales volume of US$500 million. [0005] Nuclide myocardial perfusion imaging (MPI) is recognized as an accurate non-invasive imaging technique for the diagnosis of coronary heart disease and risk stratification of coronary heart disease. It is divided into two types: rest and stress. Stress MPI needs to meet the load standard and inject myocardial perfusion imaging agent before conducting the test. C...
