Enhanced Oral Bioavailability Through Nanoparticle- Based Solid Lipid Carrier: A Novel Approach To Drug Deliver

Solid lipid nanoparticles (SLNs) offer promising properties for drug delivery due to their use of physiologically acceptable lipids. These nanoparticles are particularly notable for their versatility in encapsulating a wide range of substances, including labile compounds like proteins and peptides, as well as lipophilic and hydrophilic drugs. SLNs are beneficial in drug delivery systems as they provide protection against degradation, both in vitro and in vivo. This protective capability is crucial for maintaining drug stability and efficacy. Additionally, SLNs can regulate drug release and target specific areas, enhancing the therapeutic impact of the medication. One of the key advantages of SLNs is their nanometer-scale size, which contributes to their ability to improve the oral bioavailability of poorly soluble drugs. By improving solubility and stability, SLNs can significantly enhance the therapeutic efficacy of such medications. The review explores the various aspects of SLNs, including their in vivo behavior, which involves understanding how they interact within the body and their ultimate fate. It also delves into the Physico-chemical characteristics of SLNs, such as size, surface properties, and drug loading capacity, which are critical for their performance. Additionally, the review discusses the lymphatic mechanism through which SLNs are transported and absorbed, highlighting their potential for targeted delivery. Finally this review covers the fabrication techniques used to produce SLNs, providing insight into the methods that optimize their performance for therapeutic applications.
