目的 比较研究格列美脲片仿制药与参比制剂的溶出行为,利用计算机模拟技术对两种制剂进行虚拟生物等效性评价。方法 通过测定格列美脲在不同pH介质中的溶解性与平行人工膜(PAMPA)渗透性,分析研究了药物的生物药剂学特征;绘制药物制剂在多种介质中的溶出曲线,比较研究格列美脲片仿制药与参比制剂的溶出行为一致性;基于制剂的溶出曲线数据,利用计算机技术模拟研究格列美脲片体外溶出与体内吸收的相关性,并对两种制剂进行虚拟生物等效性评价。结果 格列美脲的溶解性随pH值的升高而增大;渗透性随pH值的升高而降低;格列美脲片在pH 1.2与pH 5.0的介质中溶出小于10%;在pH 6.0～7.4、FaSSIF与FeSSIF介质中主成分有不同程度的溶出(20%～90%);格列美脲片在FaSSIF中的体外溶出与体内吸收之间显示出较高的相关性。结论 格列美脲的生物药剂学分类为BCS Ⅱ类,即低溶解度,高渗透性药物;格列美脲片的溶出量随着介质pH值的升高而增多,溶出速率随着介质pH值的升高而加快。制剂在pH 1.2、pH 6.0、pH 6.8与pH 7.4介质中的溶出曲线可作为格列美脲片的特征溶出曲线。仿制药与参比制剂体外溶出行为相似,虚拟生物等效性研究结果显示,两种制剂生物等效(n=24)。本实验可以为药物制剂的处方筛选、生物药剂学分类判定与生物等效性风险评价提供参考。
Abstract
OBJECTIVE To study and compare the dissolution behaviors of glimepiride tablets from two manufacturers, and investigate the correlation between dissolution and absorption. METHODS The solubility and permeability of glimepiride in different pH media were determined, and the biopharmaceutical characteristics of glimepiride tablets were studied and analyzed. The dissolution curves of glimepiride tablets in different media were plotted by the second dissolution method. The dissolution behaviors of glimepiride tablets from two manufacturers were studied and compared. Based on the data of dissolution curves in vitro, the correlation between dissolution and absorption of glimepiride tablets was studied by computer simulation. The virtual bioequivalence study of the two preparations was evaluated in silico. RESULTS The solubility of glimepiride increased with the increase of pH value; the permeability decreased with the increase of pH value; the dissolution of glimepiride tablets was less than 10% in the media of pH 1.2 and pH 5.0; the dissolution of principal components in the media of pH 6.0-7.4, FaSSIF and FeSSIF ranged from 20% to 90%; the dissolution and absorption of glimepiride tablets in FaSSIF showed high correlation. CONCLUSION Glimepiride is classified as a BCS Ⅱ class drug (low solubility and high permeability drugs).The dissolution amount and rate of glimepiride tablets increase with the increase of pH value of the medium. The dissolution curves of glimepiride tablets in media of pH 1.2, pH 6.0, pH 6.8 and pH 7.4 could be used as the characteristic dissolution curves of the preparation. The reference preparation A and generic preparation B of glimepiride tablets are similar in dissolution behavior and shows bioequivalence in the virtual bioequivalence study (n=24). This study can provide reference for drug formulation screening, biopharmaceuticals classification determination and bioequivalence risk assessment.
