雷公藤合剂是我院治疗类风湿性关节炎的一种复方液体制剂,1981年通过湖北省科技成果鉴定,在临床应用十几年,治疗患者十多万人,疗效显著。但由于该制剂为粗品中药液体制剂,稳定性较差,特别是贮存一段时间后澄明度与卫生学存在一定问题。为此,我们在对雷公藤合剂进行工艺改进的同时,进行了剂型改造,在不改变原处方及提取工艺的情况下,将其制成冲服颗粒剂,取得满意的效果。现将雷公藤合剂及冲剂的制备与质量标准介绍如下。
Leigongteng Mixture is a compound liquid preparation for treating rheumatoid arthritis in our hospital. It passed the scientific and technological achievements appraisal in Hubei Province in 1981. It has been used clinically for more than 10 years and treats more than 100,000 patients. The curative effect is remarkable. However, because the preparation is a crude Chinese medicine liquid preparation, the stability is poor, and there are certain problems in clarity and hygiene after a certain period of storage. For this reason, we have made improvements to the formulation of the Tripterygium wilfordii mixture while improving the dosage form. Without changing the original prescription and the extraction process, we have made it into a granule for flushing to achieve a satisfactory result. The preparation and quality standards of Leigongteng mixture and granules are described below.
