Solid lipid nanoparticles (SLN) have emerged as a next-generation drug delivery system with potential applications in pharmaceutical field, cosmetics, research, clinical medicine and other allied sciences. Recently, increasing attention has been focused on these SLN as colloidal drug carriers for incorporating hydrophilic or lipophilic drugs. Proteins and antigens intended for therapeutic purposes may be incorporated or adsorbed onto SLN, and further administered by parenteral routes or be alternative routes such as oral, nasal and pulmonary. The obstacles associated with conventional chemotherapy may be partially overcome by encapsulating them as SLN. The present review focuses on the utility of SLN in terms of their advantages, production methodology, characterization and applications. If properly investigated, SLNs may open new vistas in therapy of complex diseases.DOI: http://dx.doi.org/10.3329/icpj.v1i11.12065 International Current Pharmaceutical Journal 2012, 1(11): 384-393

Glioblastoma multiforme (GBM) is the most common and malignant type of brain tumor. In fact, tumor recurrence usually appears a few months after surgical resection and chemotherapy, mainly due to many factors that make GBM treatment a real challenge, such as tumor location, heterogeneity, presence of the blood-brain barrier (BBB), and others. Solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) represent the most promising carriers for therapeutics delivery into the central nervous system (CNS) owing to their inherent ability to cross the BBB. In this review, we present the main challenges in GBM treatment, a description of SLNs and NLCs and their valuable role as drug carriers in GBM treatment, and finally, a detailed description of all modification strategies that aim to change composition of SLNs and NLCs to enhance treatment outcomes. This includes modification of SLNs and NLCs to improve crossing the BBB, reduced GBM cell resistance, target GBM cells selectively minimizing side effects, and modification strategies to enhance SLNs and NLCs nose-to-brain delivery. Finally, future perspectives on their use are also be discussed, to provide insight about all strategies with SLNs and NLCs formulation that could result in drug delivery systems for GBM treatment with highly effective theraputic and minimum undesirable effects.

Background: The oral application of drugs is the most popular route through which the systemic effect can be achieved. Nevertheless, oral administration is limited by difficulties related to physicochemical properties of the drug molecule, including low aqueous solubility, instability, low permeability, and rapid metabolism, all of which result in low and irregular oral bioavailability. Objective: The enhancement of oral bioavailability of drug molecules with such properties could lead to extreme complications in drug preparations. Oral lipid based nanoparticles seems to possess extensive advantages due to their ability to increase the solubility, simplifying intestinal absorption and decrease or eradicate the effect of food on the absorption of low soluble, lipophilic drugs and therefore improving the oral bioavailability. Method: The present review provides a summary of the general theory of lipid based nanoparticles, their preparation methods as well as their oral applications. Moreover, the oral drug delivery challenges are discussed. Results: According to this review, the most frequent types of lipid-based nanoparticle, the solid lipid nanoparticles and nanostructured lipid carriers are potent oral carriers due to their ability to penetrate the oral drug adsorption barriers. Moreover, such lipid nanoparticles can be beneficial drug carriers against cardiovascular risk disorders as diabetes, hypertension etc. Conclusion: In this review, the most current and promising studies involving Solid Lipid Nanoparticles and Nanostructured Lipid Carriers as oral drug carriers are reported aiming to assist researchers who focus their research on lipid based nanoparticles.

Over the last few years, there has been a significant consideration of solid lipid nanoparticles (SLNs) as an alternative method to other colloidal dispersion methods for drug delivery. Special consideration has been given to the use of SLNs as a drug carrier in recent years. SLNs are aqueous dispersions in which the colloidal particles consist of solid lipids that are biodegradable. As a result of their physical stability, the protection of the entrapped drug from decomposition, the provision of controlled drug release, and the exceptional acceptability, SLNs have several advantages over other drug carriers. This article focuses on the techniques of SLNs preparation and characterization, the effect of formulation variables on SLNs properties, the routes of administration, and the pharmaceutical applications. The data used for this review was collected by searching on Google Scholar and PubMed using the following keywords during the period from 2010 to date.

The objective of present investigation was to enhance brain penetration of Lamivudine, one of the most widely used drugs for the treatment of AIDS. This was achieved through incorporating the drug into solid lipid nanoparticles (SLN) prepared by using emulsion solvent diffusion technique. The formulations were characterized for surface morphology, size and size distribution, percent drug entrapment and drug release. The optimum rotation speed, resulting into better drug entrapment and percent yield, was in the range of 1000-1250 r/min. In vitro cumulative % drug release from optimized SLN formulation was found 40-50 % in PBS (pH-7.4) and SGF (pH-1.2) respectively for 10 h. After 24 h more than 65 % of the drug was released from all formulations in both mediums meeting the requirement for drug delivery for prolong period of time.

One of the situations in the treatment of disease is the delivery of efficacious medication of appropriate concentration to the site of action in a controlled and continual manner. Nanoparticle represents an important particulate carrier system, developed accordingly. Nanoparticles are solid colloidal particles ranging in size from 1 to 1000 nm and composed of macromolecular material. Nanoparticles could be polymeric or lipidic (SLNs). Industry estimates suggest that approximately 40% of lipophilic drug candidates fail due to solubility and formulation stability issues, prompting significant research activity in advanced lipophile delivery technologies. Solid lipid nanoparticle technology represents a promising new approach to lipophile drug delivery. Solid lipid nanoparticles (SLNs) are important advancement in this area. The bioacceptable and biodegradable nature of SLNs makes them less toxic as compared to polymeric nanoparticles. Supplemented with small size which prolongs the circulation time in blood, feasible scale up for large scale production and absence of burst effect makes them interesting candidates for study. In this present review this new approach is discussed in terms of their preparation, advantages, characterization and special features.
