隨著我國藥品研發(fā)與生產(chǎn)行業(yè)的不斷發(fā)展，以及相關(guān)法律法規(guī)與檢查機(jī)制的逐步完善，原料、輔料及成品的粉體性質(zhì)逐漸被重視，尤其是在吸入制劑領(lǐng)域，粒度分布作為粉體重要性質(zhì)之一，對于產(chǎn)品的質(zhì)量和性能起著至關(guān)重要的作用。檢測粒度分布的方法種類繁多，對常見幾種檢測方法進(jìn)行比較研究，介紹粒度檢測在口服吸入制劑研發(fā)中的重要性。

Along with the continuous development of pharmaceutical research and manufacturing industry in China, as well as the gradual improvement of relevant laws and regulations and inspection mechanism, the powder properties of raw materials, excipients and finished products are gradually valued by researchers, especially in the field of inhalation preparations, particle size distribution, as one of the important qualities of powder, plays an important role in the quality and performance of products. There are many methods to detect the particle size distribution. In this paper, several common detection methods are compared, and the importance of particle size detection in the development of oral inhalation preparations is introduced.
