中药浸膏片:骨刺片、半浸膏片、银翘解毒片等。在按《中国药典》(1977版)所规定方法测定崩解时限过程中有以下因素影响到崩解时限。在测定崩解时限时,由于中药浸膏片接触水后,片剂表面就被一层粘性极大的稠膏所包裹,因而使毛细管阻塞,阻止水份的进一步渗入。在崩解仪玻管上下运动中,被测定的五片片剂就有极大可能相互粘结。由于被测定片剂互相粘结而使表面积减少,因而延长崩解时限。同时,崩解后往往呈粘稠浆状,不能顺利地通过筛网,故崩解时间有不同程度的延长。
Chinese medicine extract tablets: bone puncture tablets, semi-paste tablets, Yinqiaojiedu tablets. The following factors influence the disintegration time limit in the measurement of the disintegration time limit according to the method prescribed in the Chinese Pharmacopoeia (1977 edition). In the determination of the disintegration time limit, since the Chinese medicine extract tablet is exposed to water, the tablet surface is covered with a thick sticky thick paste, thereby blocking the capillaries and preventing further infiltration of water. In the up and down movement of the disintegrator tube, the five tablets to be tested are highly likely to adhere to each other. Due to the adhesion of the tablets to be measured, the surface area is reduced, so that the disintegration time limit is prolonged. At the same time, after the disintegration, it tends to be thick paste and cannot smoothly pass through the screen, so the disintegration time is prolonged in different degrees.
