摘要
目的：研究不同基质阿昔洛韦（ＡＣＶ）外用制剂的药物溶出度，为开发新的ＡＣＶ外用制剂提供依据。方法：用固体药物溶出试验仪测定３种基质、５个浓度的试样，比较各自的单位面积释药量（Ｍ）及累积释药百分率（Ｑ）。结果：Ｍ值随主药浓度增加而增加，Ｑ随主药浓度增加而降低；药物溶出速率：凝胶剂＞霜剂＞乳剂型软膏，凝胶剂的溶出速率是霜剂的２倍。结论：ＡＣＶ凝胶的药物溶出优于霜剂和乳剂型软膏。
OBJECTIVES: To study the dissolution amounts of aciclovir (ACV) from differently based preparations and provide the evidence for the developement of new preparation of ACV. METHOD: The dissolution tester was applied for the quantitative determination of ACV released from 3 based formulations and 5 concentrations samples. The release amount per unit area (M) and the accumulative release percentage (Q) were compared respectively. RESULTS: The value for M was raised with the increase of the concentration of aciclovir in preparations, and for Q was reduced. The release rates of the aciclovir gel were at least two times faster than the creams and the ointment. CONCLUSION: The drug dissolution from ACV gel was better than the creams and the ointment. 10 g·kg-1 ACV in prearation was the suitable concentration.
