目的 采用国家药品监督管理局发布的指导原则对不同企业格列吡嗪控释片仿制制剂及其参比制剂的乙醇剂量倾泻情况进行对比研究.方法 采用高效液相色谱法测定格列吡嗪控释片仿制制剂及其参比制剂在不同乙醇浓度中的体外释放行为,绘制溶出曲线,采用溶出相对变化率来评价乙醇对药物释放的增速作用,并通过计算相似因子(f2)评价不同制剂体外释放的相似性.结果 随着乙醇浓度的升高,在5%、20%乙醇溶液中仿制制剂与参比制剂的体外释放量几乎无变化,在40%乙醇中释放量均出现了一定的升高,但其相似因子f2 均未低于50,与无乙醇的盐酸介质释放特性相似,同时仿制制剂体外释放行为与参比制剂相似.结论 仿制制剂符合一致性评价质量标准.0%～40%浓度的乙醇对格列吡嗪控释片的体外释放行为无显著性影响,推测制剂中的亲水性辅料及独特的双层渗透泵结构是消除乙醇剂量倾泻影响的关键因素,对格列吡嗪与酒精饮料同服的合理用药与安全风险预测具有一定的参考价值.
Objective To comparatively study the alcohol-induced dose dumping in glipizide controlled-release tablets from different manufacturers and their reference formulation according to the National Medical Products Administration(NMPA)guidelines.Methods The in vitro release of glipizide from generic and reference formulations at different concentrations of ethanol was examined using high-performance liquid chromatography(HPLC).Dissolution profiles were meticulously generated,and the relative change in the rate of dissolution due to ethanol was used as an index to assess its effect on drug release kinetics.Additionally,the similarity in in vitro release patterns across various formulations was quantitatively evaluated by calculating the similarity factor(f2).Results It was observed that the in vitro release profiles of generic formulations and the reference formulation underwent minimal changes at ethanol concentrations of 5%and 20%,with a noticeable increase at 40%ethanol,much like the release observed in a hydrochloric acid medium without ethanol(f2＞50),indicating that the in vitro release behavior of the generic formulations closely paralleled that of the reference formulation.Conclusion The generic formulations meet the quality standards for consistency evaluation.Ethanol concentrations ranging from 0%to 40%do not significantly affect the in vitro release behavior of glipizide controlled-release tablets.The presence of hydrophilic excipients and the unique push-pull osmotic pump structure within the formulation may play critical roles in mitigating the risk of alcohol-induced dose dumping.These findings can help predict appropriate dosing and assess the safety risk associated with consuming glipizide alongside alcoholic beverages.
