摘要
目的:建立酮洛芬贴片体外透皮释放方法学。方法:采用HPLC法测定释放液中酮洛芬的含量,测定条件:Diamonsilc18色谱柱(150mm×4.6mm,5μm),流动相为pH3.5磷酸盐缓冲液.乙腈.水(2:53:45),检测波长为253nm,流速为1.0mL·min-1,柱温25℃。以裸鼠皮肤为实验皮肤,采用Frans扩散池方法进行三批酮洛芬贴片样品的体外透皮实验。结果:在该HPLC条件下,酮洛芬与其他杂质分离良好,进样量在0.509~40.72μg·mL-1时,酮洛芬浓度与峰面积呈良好的线性关系(r=0.9999),回收率为101.09%,RSD为1.23%。三批酮洛芬贴片样品的透皮释放速率分别为18.157,17.973,20.001gg·cm-2.h-1,药物透皮释放符合零级动力学过程。结论:本文建立的酮洛芬贴片体外透皮释放方法简便,重现性好,可以用于控制产品质量。
Objective: To establish a test method for transdermal release of ketoprofen patch. Methods: An HPLC method was used to determine the content of ketoprofen. A Diamonsil C18 cohmm (150 mm ×4.6 mm, 5μm) was used for separation, the mobile phase consisted of phosphate buffer solution (pH3.5)-acetonitrile-water (2 : 53 : 45) at the flow rate of 1.0 mL. min-~, and the detection wavelength was set at 253 nm, column temperature was 25 ~C. The in vitro transdermal test was performed using nude mice skin and Frans diffusive pool, and three batch samples were verified by this method. Results: Ketoprofen was separated well from other impurity in this chromatogram condition. The calibration curve was linear in the range of 0.509 - 40.72 μg-mL-1 (r = 0.999 9). The average recovery was 101.09% and the RSD was 1.23%. The transdermal release rates of ketoprofen in three batches of patches were 18.157, 17.973 and 20.001μg·cm2.h-1, respectively. The release of ketoprofen patch followed zero order kinetic model. Conclusion: The method was simple and reproducible, which can be used to control product quality.
