在中药片剂生产中,常遇到有粘性或引湿性较强的药物。尤其在制作新的片剂品种时,虽对处方内不同性质的药物按制作要求做了不同处理。但在压片时,仍可引起粘冲现象。下面介绍压片粘冲的简易解决方法。把已制成的粘冲颗粒,再次放入烘箱内用低温烘干。压片前,根据粘冲的不同程度,用不同浓度的乙醇喷在颗粒上。一般情况下,以用手将颗粒握成团,手指轻压即散裂为度。经过酒精喷洒后的颗粒,压片时一般不会再出现粘冲的现象。乙醇浓度一般为30~50%。粘性大的颗粒,浓度应高些。反之浓度低一些。用乙醇喷洒,一次不宜过多。如仍有粘冲
In the production of traditional Chinese medicine tablets, drugs with strong stickiness or moisturizing ability are often encountered. In particular, in the preparation of new tablet varieties, different treatments for different types of drugs within the prescription have been processed according to production requirements. However, sticking may still occur during tablet pressing. Here’s a simple solution for sticking. The made sticky granules are put into an oven again and dried at a low temperature. Before tableting, different concentrations of ethanol are sprayed on the granules according to different degrees of sticking. Under normal circumstances, the particles are held together by hand, and the finger is lightly pressed, ie, spalled into degrees. Particles that have been sprayed with alcohol do not generally exhibit sticking. The ethanol concentration is generally 30-50%. For sticky particles, the concentration should be higher. On the contrary, the concentration is lower. Spray with ethanol, one should not be too much. If there is still sticking
