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: Acne vulgaris (commonly called acne) is the most prevalent skin complication of different causes with a higher prevalence in adolescents. Topical administration is used as first-choice therapy in mild acne, whereas for moderate and severe acne, systemic administration is required in addition to topical therapy. Mechanisms by which treatments act are: normalizing shedding into the pore to prevent obstruction, destruction of P.acnes, suppression of inflammation, and hormonal management. Objective: This review focuses on the novel drug delivery systems displaying a strong ground for topical treatment of acne in order to enhance the therapeutic performance of the topical antiacne agents with improved patience compliance and a concomitant reduction in the side effects. Method: This literature review was obtained from electronic search on Pubmed, Google Scholars, Researchgate, Scimago, CABI, DOAJ, CiteFactor, GLOBAL HEALTH, Universal Impact Factor, Hinari among many others and also search was conducted on individual journals and manuals. Conclusion: Amongst various novel drug delivery systems, vesicular carriers like liposomes and niosomes, micro sponges, microemulsions, solid lipid nanoparticles, hydrogels, emulsifier-free formulations, fullerenes and aerosol foams have been reported as novel topical administration of antiacne drugs. Liposomes have been extensively explored and their ability to optimize and improve topical therapy has been proved by several clinical trials. Microemulsions, microsponges, solid lipid nanoparticles and hydrogels also exhibit a tremendous potential for commercialization.

The application of nanotechnology indrug delivery systems (DDS) has been researched widely and seen an advancementover the past three decades. Since the 1970s, nanoparticles were primarilyutilised in vaccine deliveries and cancer chemotherapy. In more recent years,they have been found to hold promises for broader applications such as inproteins and therapeutic gene delivery systems. To date, there have been only ahandful of nanocarrier-loaded drugs commercialised into the pharmaceuticalmarket. More research is thus needed to facilitate a breakthrough of theseproducts into the current market. This mini-review mainly focuses on four typesof commonly utilised organic nanocarriers including micelles, compactpolymerics, solid-lipid nanoparticles and liposomal vesicles and discusses theprogress and some challenges associated with these nanoparticles (NP).

Numerous attempts have been made to improve the bioavailability from ocular drug delivery systems and to prolong the residence time of drugs applied topically onto the eye. Conventional ocular drug delivery systems such as eye drops and ointments are inefficient, whereas, systemic administration requires high doses which may result in significant toxicity. Therefore, a need arises to develop novel drug delivery carrier systems capable of increasing ocular bioavailability and decreasing both local and systemic cytotoxicity. Nanotechnology is expected to revolutionize ocular drug delivery. Solid lipid nanoparticles (SLNs) introduced in 1991 represent an alternative carrier system to traditional colloidal carriers, such as emulsions, liposomes and polymeric micro- and nanoparticles. SLNs do not show biotoxicity as they are prepared from physiological lipids and are ideal ocular drug delivery systems as they can enhance the corneal absorption of drugs and improve the ocular bioavailability of both hydrophilic and lipophilic drugs. SLNs have another advantage of allowing autoclave sterilization, an indispensible step in the formulation of ocular preparations. In this review a special attention has been given to the nature of lipids and surfactants commonly used for SLNs production. This article also reviews in detail the various fabrication methods, characterization, sterilization, and stabilization techniques for SLNs. In-vitro and in-vivo methods to study the drug release profile from SLNs have also been mentioned. A summary of previous studies involving the use of SLNs in ocular drug delivery is provided, along with a critical evaluation of SLNs as a potential colloidal ocular drug delivery system.

Antimicrobial resistance is one of the biggest threats to global health as current antibiotics are becoming useless against resistant infectious pathogens. Consequently, new antimicrobial strategies are urgently required. Drug delivery systems represent a potential solution to improve current antibiotic properties and reverse resistance mechanisms. Among different drug delivery systems, solid lipid nanoparticles represent a highly interesting option as they offer many advantages for nontoxic targeted drug delivery. Several publications have demonstrated the capacity of SLNs to significantly improve antibiotic characteristics increasing treatment efficiency. In this review article, antibiotic-loaded solid lipid nanoparticle-related works are analyzed to summarize all information associated with applying these new formulations to tackle the antibiotic resistance problem. The main antimicrobial resistance mechanisms and relevant solid lipid nanoparticle characteristics are presented to later discuss the potential of these nanoparticles to improve current antibiotic treatment characteristics and overcome antimicrobial resistance mechanisms. Moreover, solid lipid nanoparticles also offer new possibilities for other antimicrobial agents that cannot be administrated as free drugs. The advantages and disadvantages of these new formulations are also discussed in this review. Finally, given the progress of the studies carried out to date, future directions are discussed.
