用喘咳合剂治疗慢性支气管炎,在附属中医院临床应用已经多年,被认为是确有疗效的制剂。由于有文献[《中草药通讯》1977年10期]提出麻黄与黄芩两味药的有效成分——麻黄碱及黄芩甙配伍会产生沉淀以及汤剂煎煮使用不便和冲剂不能按中医辨证加减药物的问题,我们采用了喷雾干燥技术,制备一种新型的中药粉剂。这种粉剂用水冲化即为汤剂,具有速溶、卫生、生产简便等优点,本试验还证 Treating chronic bronchitis with a mixture of asthma and cough has been used for many years in clinical hospitals affiliated with TCM, and it is considered to be a curative agent. Because of the literature [Chinese Herbal Medicine Newsletter, Issue 10, Issue 1977], it is proposed that the combination of ephedrine and astragalus, the active ingredients of ephedra and astragaloside, will cause sedimentation, and the inconvenience caused by decoction and granules may not be added or subtracted according to TCM syndrome differentiation. For the problem, we adopted a spray drying technique to prepare a new type of Chinese medicine powder. The powder is decocted with water, which has the advantages of instant dissolving, sanitation, and simple production.
