1、 双黄连颗粒剂制备工艺的研究摘要 研究目的：研究双黄连颗粒剂制备的现代化工艺，并对其所制备的双黄连颗粒进行质量考察，以确定制备工艺的科学性和合理性。 研究方法： 在本文的研究中，首先确定双黄连颗粒制备的处方用药量（金银花260g,黄芪260g,连翘520g,三者的用药比例符合1:1:2)。再深入研究金银花、黄芪、连翘的提取工艺和浓缩工艺，从而得到药物清膏约为160g(相对密度为1.22-1.26）。双黄连颗粒剂所选用的辅料为糊精和蔗糖，分别选取药物（清膏）：蔗糖：糊精不同的浓度配比，通过颗粒剂的制备工艺制备不同的双黄连颗粒，通过颗粒的疏松性状、吸湿性、溶化性、口感进行评价，筛选合理的药物（清膏
2、）：蔗糖：糊精的配比浓度。同时对颗粒剂采用不同温度的烘箱进行干燥，通过干燥时间和成粒状态两个指标，测定颗双黄连颗粒烘干的最佳温度。对制成的双黄连颗粒进行崩解时间和含水量的检测，和通过中试工艺进行验证批量生产的可行性。研究结果：1. 3号颗粒（辅料配比为1:3.8:0.6）综合评定效果最为理想，颗粒性状疏松、而吸湿性在2天符合颗粒制剂的要求，溶化性为溶液澄清（药物的溶化性效果理想），口感为甜（符合矫味剂的特点）。2. 60和70烘干后，整粒效果最为理想，颗粒都能达到疏松状态，可直接过筛，然而60的烘干时间为48h,时间过长，从大批量工艺生产和效率的角度考虑，选择70作为颗粒制备的最好烘干温度。3
3、. 3号颗粒和4号颗粒的含水量明显低于1号颗粒和2号颗粒，即3号颗粒和4号颗粒的防潮性明显强于1号颗粒和2号颗粒。而3号颗粒在崩解时间上为2.8分钟， 明显强于4号颗粒的4.6min,因此，可以确定辅料配比（药物：蔗糖：糊精）为1:3.8:0.6。4. 三批中试样品在水分、性状、溶化性、粒度和含量上都符合双黄连颗粒制剂的标准和规定。研究结论：1.双黄连颗粒制剂的合适辅料配比（药物：蔗糖：糊精）为1:3.8:0.6。2.从大批量工艺生产和效率的角度考虑， 70作为双黄连颗粒制备的最好烘干温度。3.本文以1:3.8:0.6的辅料配比，制备的双黄连颗粒中试试验效果理想，性状稳定，工艺简单，符合大批量
