影响葛根总黄酮生物粘附片体外释放度的因素研究
Experimental Study on the Factors Affecting in Vitro Dissolubility of Total Puerariae Flavones Bioadhesive Tablets
【摘要】 目的 :探讨影响葛根总黄酮生物粘附片释放度的主要因素。方法 :以羟丙基甲基纤维素 (HPMC)与卡波姆 (CP)为生物粘附材料和骨架材料、乳糖为致孔剂制备葛根总黄酮生物粘附片 ;采用转篮法测定释放度 ,以0 1mol/LHCl为溶出介质 ,转速为100r/min ,测定累积释放度 ,同时考察HPMC用量、CP用量、致孔剂种类、乳糖用量、压片颗粒大小、介质 pH等因素对释放度的影响。结果与结论 :HPMC用量、CP用量、致孔剂种类、乳糖用量、压片时颗粒大小、介质 pH等因素对生物粘附片溶出均有明显影响
【Abstract】 OBJECTIVE:To study the main factors affecting in vitro dissolubility of total puerariae flavones(TPF)bioadˉhesive tablets.METHODS:Using HPMC,Carbopol(CP934NP)as bioadhesive and base materials,lactose as porogenic agent to prepare bioadhesive tablets;Basket-rotating method was adopted to determine the dissolubility while0.1mol/L HCl was used as dissolution medium,Rotational speed was100r/min.The accumulated dissolution was detected and the influence of the amount of HPMC,CP,kind of porogenic agent,amount of lactose,size of granules in pressed tablets and medium pH on dissolubility was observed.RESULTS&CONCLUSION:The amount of HPMC,CP and lactose,kind of porogenic agent,size of granules in tablets and medium pH can affect the dissolubility of bioadhesive tablets.
