硬脂酸是一種優良的光滑剂,但難於研成細粉,一般使用為藥片的光滑劑時須溶解於乙醚中,再噴於颗粒上;但乙醚容易挥發,處理不便,且其成本較高,故多將硬脂酸製成鎂鹽或鈣鹽以供使用,京滬各大藥廠,製片時已普遍採用其鎂鹽。作者也感到硬脂酸用乙醚或热酒精等溶解後,用霧化器噴於顆粒上,待溶媒揮發後壓片的方法不方便,成本較高。但所採 Stearic acid is an excellent smoothing agent, but it is difficult to develop into fine powder. Generally, when used as a smoothing agent for tablet, it must be dissolved in ether and sprayed on the particles. However, ether is easily volatilized, inconvenient to handle, and its cost is lower. High, so many stearic acid made of magnesium or calcium salt for use, Beijing and Shanghai major pharmaceutical companies, the film has been widely used when its magnesium salt. The authors also felt that stearic acid was dissolved with ether or hot alcohol and sprayed on the particles with an atomizer. After the solvent was volatilized, the tableting method was inconvenient and costly. But what
