目的:制备美洛昔康凝胶剂,并建立其质量控制方法。方法:拟定处方组成及制备工艺;采用紫外分光光度法测定美洛昔康含量。结果:美洛昔康的线性范围为2.4～19.2μg·ml~(-1);平均回收率为100.1%;脚为0.3%(n=5)。结论:该凝胶剂制备工艺简单,含量测定方法准确可靠,重复性好,可用于该制剂的质量控制。
Objective: To prepare meloxicam gel and to establish its quality control method. Methods: To formulate the prescription composition and preparation process; to determine the content of meloxicam by ultraviolet spectrophotometry. Results: The linear range of meloxicam was 2.4 ~ 19.2μg · ml ~ (-1), the average recovery was 100.1% and the foot was 0.3% (n = 5). Conclusion: The preparation method is simple, the content determination method is accurate and reliable, and the repeatability is good. It can be used for the quality control of the preparation.
