双氯芬酸钠-β-环糊精包合物的研制

 目的：制备双氯芬酸钠-β-环糊精包合物考察其有关性质。方法：采用共沉淀法制备双氯芬酸钠-β-环糊精包合物。结果：经UV，IR，DSC及相溶解度图法鉴定，表明双氯芬酸钠与β-环糊精确已形成包合物，含量测定证明包合物主、客分子比为1：1。结论：双氯芬酸钠-β-环糊精包合物可明显提高双氯芬酸钠的溶解度、溶出速度，并减小其对胃粘膜的刺激性。

The preparation of inclusion compound of diclofenac sodium-β-cyclodextrin

OBJECTIVE: To prepare the inclusion compound of diclofenac sodium (DFS)-β-cyclodextrin (β-CD) and investigate its properties. METHOD: The inclusion compound of DFS-β-CD was prepared by the co-precipitation method. RESULTS: The inclusion compound of DFS-β-CD was confirmed by UV absorption spectrum, IR absorption spectroscopy, differential scanning calorimetry (DSC) and phase solubility diagram. Meanwhile, the content analysis of the inclusion compound showed that the molecular ratio of DFS to β-CD was 1∶1. CONCLUSION: The soluability and dissolution rate of DFS were increased and its irritation to stomach was reduced when the drug was included by β-CD.
