Abstract: This review describes the use of Lipid-based Nanocarriers (LNCs) for the parenteral delivery of pharmaceutical actives. Firstly, the two generation of LNCs such as ‘‘solid lipid nanoparticles’’ (SLNs) and ‘‘nanostructured lipid carriers’’ (NLCs) are explained in term of preparation, characterization and stability. Although the use of LNCs through parenteral administration has shown many benefits, their use is limited by opsonization, an immune process that causes their short half-life (3-5 min). Therefore, many strategies are discussed to realize “stealth” systems suitable for parenteral administration. Successfully, the requirements and applications of parenteral lipid nanoparticles are reviewed for the delivery of natural compounds, synthetic drugs and genetic materials. In the last period, the latter application has been a remarkable interest due to the numerous benefits of mRNA vaccines to fight the Covid-19 pandemic.

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.

Injection Process

Solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) have emerged as potential drug delivery systems for various applications that are produced from physiological, biodegradable, and biocompatible lipids. The methods used to produce SLNs and NLCs have been well investigated and reviewed, but solvent injection method provides an alternative means of preparing these drug carriers. The advantages of solvent injection method include a fast production process, easiness of handling, and applicability in many laboratories without requirement of complicated instruments. The effects of formulations and process parameters of this method on the characteristics of the produced SLNs and NLCs have been investigated in several studies. This review describes the methods currently used to prepare SLNs and NLCs with focus on solvent injection method. We summarize recent development in SLNs and NLCs production using this technique. In addition, the effects of solvent injection process parameters on SLNs and NLCs characteristics are discussed.

Background:The high molecular weight and increasing lipophilicity drug face many problems starting from the drug development to formulation and conduction of pharmacological, toxicological and pharmacokinetic studies to its biological application. To overcome this problem, a different formulation of nano-sized drugs was developed recently. The use of Solid lipid nanoparticles (SLNs) and Nanostructured lipid carriers (NLCs) offers new insight into the formulation of the poorly soluble drug.Objective:The study aimed to investigate the literature with regard to the development of SLNs and NLCs for lipid-based nano drug delivery of poorly soluble drugs, with a view to identifying the factors influencing the optimization of the formulation of SLNs and NLCs and strategies to decrease the use of organic solvent during the preparation.Results:This review highlights the simple and easily scaled-up novel lipid nanoparticles (SLNs and NLCs) and their factors to be considered in the formulation for the proper selection of excipients. Also, this review summarizes the research findings reported by the different researchers regarding the principle formulation components, different preparation techniques, characterization, and toxicology of lipid nanoparticles.Conclusion:The SLNs/NLCs make this drug delivery system as one of the promising delivery systems, and safe colloidal lipid carriers for the delivery of poorly soluble drug and will be a solution to the formulation scientist for the solubility and permeability problem associated with the drugs to assure its good bioavailability.

Background: The clinical efficacy of the topical tretinoin is widely studied and has been well established for many therapeutic interventions, among some, photoaging, acne, and melasma. However, the side effects, mainly cutaneous irritation, erythema, xerosis and peeling, remain major obstacle to the patient compliance. Besides, the insight regarding the drug delivery profile is essential to understand the therapeutic action of the drug. Methods: Through bibliographic research in databases we highlight further advances and an update on tretinoin delivery systems such as liposomes, niosomes, solid lipid nanoparticles, nanostructured lipid carriers, cyclodextrins, nanostructured polymers and other technological systems that reduce its side effects and improve the permeation profile to potentiate efficacy and drug safety on the skin. Results: Pharmaceutical preparations were developed and evaluated for permeability in in vitro models using pig ear, snake, mouse and human skin, and potential for irritation was also verified using release systems for tretinoin and compared to available commercial formulations. Overall results indicated the composition, charge and size of the system influences the tretinoin delivery, modulating the type of release and its retention. Small unilamellar vesicles promoted greater cutaneous delivery of tretinoin. Negative charge, for both liposomes and niosomes, can improve pig skin hydration as well as the tretinoin retention. The quantity of solid lipids and the type of oil used in the composition of solid lipid nanoparticles and nanostructured lipid carriers affected percutaneous drug delivery. Conclusion: As evident from the literature, the tretinoin technological delivery systems consist an innovative and potential management for increasing the patient compliance presenting safety and efficacy.
