摘要
目的对布洛芬原位凝胶剂进行体外溶蚀和释放度考察,探索处方中布洛芬与PVP K30的最佳比例。方法采用无膜溶出法,根据公式凝胶累积溶蚀百分率=(W1-Wt)/(W1-W0)来计算溶蚀率;根据标准曲线,利用峰面积计算药物累积释放率。结果当布洛芬∶PVP K30=1∶1时,制成的凝胶的性质最好。随着时间的递增,凝胶的溶蚀率和释放率显著增加。结论布洛芬凝胶剂具有良好的缓释效果。
Objective The erosion and dissolution for in-situibuprofen was studied in order to optimize the ratio of ibuprofen and PVP K30 in the prescription.Method The membrane-free method was used.The erosion rate was calculated according to the formula,cumulative erosion percentage=（W1-Wt）/（W1-W0）.The drug cumulative release rate was calculated by using the peak area according to the standard curve.Results When the proportion of ibuprofen and PVP K30 was 1∶1,the ratio of erosion and release increased significantly with the increase of time.Conclusion The in situibuprofen gels showed excellent sustained release characteristics.
