【摘要】：目的:制備兩性霉素B脂質體并對其藥動學進行研究。方法:采用有機溶劑注入法制備兩性霉素B脂質體,用微射流進行整粒,用動態(tài)光散射法測定粒徑,采用Ultrafree-CL離心超濾管分離游離兩性霉素B(F-AMB)與復合兩性霉素B(L-AMB)檢測包封率,用Wistar大鼠進行藥動學研究。結果:兩性霉素B脂質體平均粒徑為(115±20)nm;包封率99.9%;大鼠靜脈注射,實驗藥與Amphotec汶的Cmax,AUC0~168 h和AUC0~∞無顯著性差異(P0.05)。結論:采用有機溶劑注入法制備兩性霉素B脂質體具有較高包封率,在大鼠體內的藥動學特征與Amphotec汶一致。
[Abstract]:Objective: to prepare amphotericin B liposome and study its pharmacokinetics. Methods: amphotericin B liposomes were prepared by organic solvent injection. The entrapment efficiency of free amphotericin B (F-AMB) and compound amphotericin B (L-AMB) was determined by Ultrafree-CL centrifugation ultrafiltration tube. The pharmacokinetics of Wistar rats was studied. Results: the mean particle size of amphotericin B liposomes was (115 鹵20) nm; entrapment efficiency 99.9, and there was no significant difference in Cmax,AUC0~168 h and AUC0~ 鈭，
