摘要
目的:采用半固体骨架技术提高黄豆苷元的体外溶出度。方法:采用熔融法制备黄豆苷元半固体骨架胶囊,比较不同载体材料聚氧乙烯(40)硬脂酸酯(S-40)、泊洛沙姆、聚乙二醇(PEG)4000,不同含药量(2%、4%、6%),表面活性剂吐温-80不同用量(15%、20%、25%、30%)对其体外溶出度的影响并与市售胶囊进行比较。结果:上述3种影响因素中溶出度较优的选择为采用S-40为载体,含药量为2%,吐温-80用量20%。所制胶囊体外溶出速率快于市售胶囊。结论:半固体骨架技术能够提高难溶性药物黄豆苷元的体外溶出度。
OBJECTIVE: To enhance the dissolution of daidzein by semisolid matrix technique. METHODS : Semi - solid matrix capsules were prepared by fusion method. The influences of different carriers including polyoxyethylene (40), stearate (S- 40), poloxamer, and polyethylene glycol (PEG) 4000, drug contents (2%, 4%, and 6%), contents of surfactants- tween 80 (15%, 20%, 25%, and 30% ) on the dissolution in vitro were analyzed and which were compared with the common capsules sold in the market. RESULTS: Optimal dissolution was obtained when the condition of the above three factors was as follows: the carrier was S- 40; the drug content = 2%, and the content of twieen- 80 : 20%. The dissolution rate of the capsule prepared in this condition was higher than that of the common capsule. CONCLUSION: The in vitro dissolution rate of daidzein (which is hard to dissolve) could be enhanced by semi- solid matrix technique.
