Problems solved by technology

Patent WO2009061713 discloses an oral preparation containing compound 1, which is prepared by dry granulation process, and the obtained preparation can achieve a dissolution rate of more than 70% in 20 minutes, but this method does not disclose specific technical parameters (such as granulation technology, large sheet density, etc.), and it does not imply that the control of specific technical parameters is conducive to the improvement of the technology level; in fact, for the preparation of compound 1, the same qualified dissolution rate of the preparation can correspond to different preparation processes, although different Preparations with qualified dissolution performance can be prepared by any preparation process, but it is still necessary to optimize the process level through the adjustment of technical parameters, so as to simplify the process and improve product quality (such as pass rate, etc.)

According to the present invention, by controlling the bulk density during a dry granulation process within a specific range, the granulation level of the dry granulation is improved, the preparation process is optimized, the preparation quality is improved, and the obtained product is suitable for the clinical application compared to the product prepared in the prior art.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to an oral preparation for treating cardiovascular diseases and a preparation method thereof. Background technique [0002] The prevalence of risk factors for cardiovascular disease in my country is obvious. With the development of society and economy, the national lifestyle has undergone profound changes, especially the aging of the population and the acceleration of urbanization. The prevalence of risk factors for cardiovascular disease in China is on the rise. , leading to a continuous increase in the incidence of cardiovascular disease. Overall, the prevalence and mortality of cardiovascular diseases in my country are still on the rise, and the number of patients with cardiovascular diseases will continue to grow rapidly in the next 10 years. At present, the death caused by cardiovascular disease accounts for the first place in the total death of urban and rural reside...
