本文描述了迄今为止开发的用于眼部局部给药的药物形式,即滴眼液、软膏、原位凝胶、插入物、多室给药系统和具有生物粘附特性的眼科药物形式。到目前为止,许多研究表明,新的和更复杂的眼科药物形式比传统药物具有优势,能够通过降低药物形式对人眼防御机制的敏感性,延长药物与角膜的接触时间,增加药物通过眼睛复杂解剖结构的渗透,以及提供药物在眼组织中的控制释放等方式提高活性物质的生物利用度。这可以减少药物的使用频率。本文的其余部分描述了各种眼科药物形式的体外和体内推荐研究,以便从期望的性质和患者的依从性角度评估该形式是否可接受。
This paper describes hitherto developed drug forms for topical ocular administration, that is, eye drops, ointments, in situ gels, inserts, multicompartment drug delivery systems, and ophthalmic drug forms with bioadhesive properties. Heretofore, many studies have demonstrated that new and more complex ophthalmic drug forms exhibit advantage over traditional ones and are able to increase the bioavailability of the active substance by, among others, reducing the susceptibility of drug forms to defense mechanisms of the human eye, extending contact time of drug with the cornea, increasing the penetration through the complex anatomical structure of the eye, and providing controlled release of drugs into the eye tissues, which allows reducing the drug application frequency. The rest of the paper describes recommended in vitro and in vivo studies to be performed for various ophthalmic drugs forms in order to assess whether the form is acceptable from the perspective of desired properties and patient's compliance.
