Figure imgf000020_0003
从上面的实施例及有关物质的测定结果可以看出,在添加了抗氧 剂后, 含雷沙吉兰的贴片、 凝胶、 软膏、 乳膏、 巴布剂、 膜剂、 喷雾 剂获得了出乎意料的热稳定性,这对组合的储存有着很大的益处。相 对于 CN101032474和 CN101606923A中描述的体系而言, 稳定性较 好、制备更简便,而且对于 CN101606923A,对皮肤的粘附性能更好。 尤其是贴片, 加入抗氧剂作为稳定剂后, 对基质的选材不苛刻, 材料 易得,且对皮肤的粘性更好,不易脱落,且能保持较高的累积渗透量。 本发明的药用组合物因选材不苛刻, 材料易得, 也可降低生产成本, 工业操作简便。 以上通过举例说明的方式描述了本发明。但是, 应当理解, 本发 明绝不仅仅限于这些具体实施方式。普通技术人员可以对本发明进行 各种修改或变动, 而这些修改和变动都属于本发明的保护范围。
