The synthesis, application and therapeutic perspectives of medicinal plants-based solid lipid nanoparticles: a comprehensive review

Abstract

Lipid-based drug carriers have gained massive amounts of interest in the last two-decade period as a way to deliver drugs that are not particularly water-soluble. Pharmaceutical uses of lipid nanocarriers include carrying and administering a wide range of therapeutic ingredients. Solid lipid nanoparticles (SLNs) were designed and formulated to rise above the disadvantages of existing colloidal systems, including microemulsions, liposomes and polymeric nanoparticles, by offering benefits such as a favorable release profile and targeted medication distribution while having great physical integrity. We sought to evaluate the recent findings on the current issue to provide a comprehensive perspective of the subject utilizing an extensive literature search to pinpoint the latest scientific reports on this subject. The focus of this paper is on the research employing SLNs for delivery of medicinal plants and testing them in vitro and in vivo. There are a number various standard variables affecting the release of compounds from SLNs throughout all administration routes. Further, the current paper comprehensively elucidates assorted prospects of SLNs. Next, the investigated SLNs encapsulating herbal compounds in scientific articles are reviewed in details. As many herbal compounds are hydrophobic substances, the SLNs encapsulating them can be beneficial in various therapeutic applications. The most studies herbal compounds are Curcumin, followed by Silibinin and Artemisinin.
