    [摘要] 目的:研制盐酸地匹福林眼用凝胶剂。 方法:建立高效液相色谱法测定制剂的含量及体外释药量,采用透析膜扩散法进行处方的体外释药实验,应用离体角膜进行体外渗透实验。 结果:亲水凝胶材料含量越小,盐酸地匹福林从凝胶基质中释放越快,凝胶体外释药符合一级释放动力学方程,离体角膜渗透行为符合一级释放规律。 结论:盐酸地匹福林眼用凝胶达到了延迟释放的目的。

    [Abstract] Objective: To study dipivefrin hydrochloride ophthalmic gel-forming solution. Methods: The release test of formation was conducteded by using permeable membrane. The content and the release amount of dipivefrin hydrochloride from the gel base were determined by high performance liquid chromatography. The cornea permeation test of formulation was studied by using rabbit corneas. Results: The formulation release behavior in vitro followed the first-order kinetic equation. The permeabilities of dipivefrin hydrochloride were raised significantly with the less amount of polymer in the formulation. The formulation permeation behavior in vitro followed the first-order kinetic equation. Conclusion: Dipivefrin ophthalmic gel-forming has longer release time than that of eyedrops.
