摘要
背景:药物毒性和无效是药物治疗失败的常见问题。针对这些问题,人们开展了大量的研究工作,目的是设计新的给药剂型,特别是纳米粒子系统。这些系统的设计是为了在减少副作用的同时,增加将治疗分子运送到所需部位的数量。为了实现这一目标,纳米载体必须主要表现出合适的药物载体化能力和药物分子的受控生物命运。只有纳米医学的智能设计才能完成这些基础。方法:本综述旨在探讨纳米医学制备中应考虑的重要基础。这包括治疗剂、成像剂、纳米载体和功能化结构。特别讨论了如何控制纳米医学在体内的命运的高潜力制造方法的解释和汇编。最后,还讨论了一些基于纳米技术的药物给药系统,以促进纳米医学的发展.结果:基于纳米技术的药物给药系统在被动靶向和主动靶向以及药物药效学和药代动力学特征的改善方面表现出了显著的效果。多功能纳米载体的概念为最大限度地提高治疗分子的有效性、安全性和监测治疗分子的生物学命运提供了一种革命性的药物传递方法。结论:纳米药物可提高治疗分子的疗效,降低其毒副作用。同时,还需要进一步的研究工作,以正确地优化(并定义)这些纳米药物的有效性、纳米毒性、体内命运和可行性,从临床前的角度来看,这些纳米药物实际上是有希望的。

摘要: Background: Drug toxicity and inefficacy are commonly experienced problems with drug therapy failure. To face these problems, extensive research work took place aiming to design new dosage forms for drug delivery especially nanoparticulate systems. These systems are designed to increase the quantity of the therapeutic molecule delivered to the desired site concurrently with reduced side effects. In order to achieve this objective, nanocarriers must principally display suitable drug vehiculization abilities and a controlled biological destiny of drug molecules. Only the intelligent design of the nanomedicine will accomplish these fundamentals.
Methods: The present review article is dedicated to the discussion of the important fundamentals to be considered in the fabrication of nanomedicines. These include the therapeutic agent, the imaging agent, the nanocarrier and the functionalization moieties. Special consideration is devoted to the explanation and compilation of highly potential fabrication approaches assisting how to control the in vivo destiny of the nanomedicine. Finally, some nanotechnology-based drug delivery systems, for the development of nanomedicine, are also discussed.
Results: The nanotechnology-based drug delivery systems show remarkable outcomes based on passive and active targeting as well as improvement of the drug pharmacodynamic and pharmacokinetic profiles. Multifunctional nanocarrier concept affords a revolutionary drug delivery approach for maximizing the efficacy, safety and monitoring the biological fate of the therapeutic molecule.
Conclusion: Nanomedicines may enhance the efficacy of therapeutic molecules and reduce their toxic effects. Meanwhile, further research works are required to rightly optimize (and define) the effectiveness, nanotoxicity, in vivo destiny and feasibility of these nanomedicines which, from a preclinical standpoint, are actually promising.
