SLNs and NLCs have remarkably wide range of properties which make them useful for several potential applications in drug delivery, clinical medicine, and research, as well as in parenteral, dermal, pulmonary and topical delivery of drugs. The unique size-dependent properties of the solid lipid nanoparticles make them at the forefront of the rapidly developing field of nanotechnology offering development of new therapeutics having reduced toxic side effects and increased treatment efficacy.
SLNs and NLCs are very attractive drug delivery candidates, primarily due to their relatively stable constituents and probable ease of drug encapsulations. The incorporation of drugs into nanocarriers like SLNs and NLCs for several levels of drug targeting offers good potential in gene transfer, cosmetic and food industry with great promise for reaching the goal of controlled and site-specific drug delivery. Lipid nanoparticle drug delivery technology presents considerable opportunities for improving medical therapeutics, but the technology's potential remains unrealized.
The review has focused on the various effective delivery routes and strategies for SLNs and NLCs, and their applicability in the encapsulation of therapeutics. Number of research works has been successfully carried out in this area. It would result in a simultaneous improvement in the quality, efficacy, and safety profile of drugs.
However, because of mentioned limitations and difficulties related to them, the total number of products on the market is still limited. Although the concept of PEGylation to increase half-life of nanoparticles revolutionized the nanoparticle-mediated drug-delivery field, significant improvements are warranted in this area.
固体脂质纳米粒(SLNs)和纳米结构脂质载体(NLCs)具有极为广泛的特性,这使得它们在药物递送、临床医学、研究以及药物的肠胃外、皮肤、肺部和局部递送等多个潜在应用领域中十分有用。固体脂质纳米粒独特的尺寸依赖性特性使其处于快速发展的纳米技术领域前沿,为开发具有降低毒副作用和提高治疗效果的新型疗法提供了可能。
SLNs和NLCs是极具吸引力的药物递送候选物,主要是由于其成分相对稳定且药物包封可能较为容易。将药物掺入SLNs和NLCs等纳米载体中以实现多个层面的药物靶向,在基因转移、化妆品和食品工业中具有良好潜力,有望实现可控和位点特异性药物递送的目标。脂质纳米粒药物递送技术为改善医学治疗提供了相当多的机会,但该技术的潜力尚未得到充分发挥。
本综述聚焦于SLNs和NLCs的各种有效递送途径和策略及其在治疗剂包封中的适用性。该领域已成功开展了多项研究工作。这将同时提高药物的质量、疗效和安全性。
然而,由于上述与之相关的局限性和困难,市场上的产品总数仍然有限。尽管聚乙二醇化以延长纳米粒半衰期的概念彻底改变了纳米粒介导的药物递送领域,但该领域仍需取得显著进展。
