Résumé :
Psoriasis is a chronic inflammatory autoimmune disorder that moderately affects social and interpersonal relationships. Conventional treatments for psoriasis have certain problems, such as poor drug penetration through the skin, hyper-pigmentation, and a burning sensation on normal and diseased skin. Colloidal drug delivery systems overcome the pitfalls of conventional approaches for psoriasis therapeutics and have improved patient safety parameters, compliance, and superior effectiveness. They also entail reduced toxicity. This comprehensive review’s topics include the pathogenesis of psoriasis, causes and types of psoriasis, conventional treatment alternatives for psoriasis, the need for colloidal drug delivery systems, and recent studies in colloidal drug delivery systems for the treatment of psoriasis. This review briefly describes colloidal drug delivery approaches, such as emulsion systems—i.e., multiple emulsion, microemulsion, and nano-emulsion; vesicular systems—i.e., liposomes, ethosomes, noisomes, and transferosomes; and particulate systems—i.e., solid lipid nanoparticles, solid lipid microparticles, nano-structured lipid carriers, dendrimers, nanocrystals, polymeric nanoparticles, and gold nanoparticles. The review was compiled through an extensive search of the literature through the PubMed, Google Scholar, and ScienceDirect databases. A survey of literature revealed seven formulations based upon emulsion systems, six vesicular drug delivery systems, and fourteen particulate systems reported for antipsoriatic drugs. Based on the literature studies of colloidal approaches for psoriasis management carried out in recent years, it has been concluded that colloidal pharmaceutical formulations could be investigated broadly and have a broad scope for effective management of many skin disorders in the coming decades.

Résumé :
Solid lipid nanoparticles (SLNs) are nanocarriers developed as substitute colloidal drug delivery systems parallel to liposomes, lipid emulsions, polymeric nanoparticles, and so forth. Owing to their unique size dependent properties and ability to incorporate drugs, SLNs present an opportunity to build up new therapeutic prototypes for drug delivery and targeting. SLNs hold great potential for attaining the goal of targeted and controlled drug delivery, which currently draws the interest of researchers worldwide. The present review sheds light on different aspects of SLNs including fabrication and characterization techniques, formulation variables, routes of administration, surface modifications, toxicity, and biomedical applications.

Résumé :
AbstractThe advancement of research in colloidal systems has led to the increased application of this technology in more effective and targeted drug delivery. Nanotechnology enables control over functionality parameters and allows innovations in biodegradable, biocompatible, and stimuli-responsive delivery systems. The first closed bilayer phospholipid system, the liposome system, has been making steady progress over five decades of extensive research and has been efficient in achieving many desirable parameters such as remote drug loading, size-controlling measures, longer circulation half-lives, and triggered release. Liposome-mediated drug delivery has been successful in overcoming obstacles to cellular and tissue uptake of drugs with improved biodistributionin vitroandin vivo. These colloidal nanovehicles have moved on from a mere concept to clinical applications in various drug delivery systems for antifungal, antibiotic, and anticancer drugs.

Résumé :
Colloidal particulate carrier systems are the systems which carry particulates in a nanometre size. These systems are substantially effective for transportation and distribution of variety of loaded drugs to desired site and increase efficacy and decrease toxicity, to provide therapeutic activity in a controlled manner for a prolonged period of time. One such new emerging colloidal systems is proniosomes which has capacity to improve the bioavailability and also permeation of drugs across the stratum corneum to provide a controlled release action and reduce toxic effects associated with drugs. These are the dry formulations of water-soluble non-ionic surfactant coated carrier systems which immediately on hydration form niosomes. They have the capacity to overcome the various problems associated with niosomes and liposomes, like instability, transportation, distribution, storage and dosing. They offer versatile drug delivery concept for both hydrophilic and hydrophobic drugs. They have the capacity to deliver drugs effectively through different routes at specific site to achieve controlled release action. This review concentrates on preparation, characterization, components, structure, types, evaluation parameters, proniosomes in drug delivery and targeting, toxicities associated with proniosomes, proniosomes versus niosomes, clinical applications, mechanism of vesicle formation in proniosomes and future trends associated with it. Also, drug delivery via different routes, such as oral, parenteral, topical and transdermal, ocular, vaginal, mucosal, pulmonary and intranasal were discussed.

Résumé :
60%-70% Several drugs can be administered orally as liquids, capsules, tablets, or chewable tablets because the oral route is the most convenient, safest and less expensive. The important challenge in the oral drug delivery is the growth of novel approaches to approve absorption of poorly permeable drugs across the intestinal permeability. The Biopharmaceutics Classification System (BCS) categorized based on their solubility and permeability. The BCS Class III, Class IV with low permeability across the biological membranes with low bioavailability. While these drugs are pharmacologically effective, poor absorption due to low permeability becomes the rate-limiting step to improve oral bioavailability. Various approaches for improving the permeability include physical, chemical, colloidal carriers and other methods such as prodrugs, permeation enhancers, ion-pairing, nanoencapsulation and combination/hybridization of one or more traditional approaches to improve drug permeability for better absorption. Among many advantages over other routes of administration 3 crucial ones are avoiding metabolism in liver, minimal negative effects and increased bioavailability.This article discusses the commonly various strategiesand various approaches for improving the permeability of BCS Class III and Class IVdrugs to enhance bioavailability.

Castro-Lopez, Vanessa. « Colloidal microgels as (trans)dermal drug delivery systems ». Thesis, University of Greenwich, 2005. http://gala.gre.ac.uk/6230/.

Texte intégral
Résumé :
In this study microgels have been used as novel drug carriers (i.e. a novel controlled drug delivery system) for either dermal or transdermal delivery. The experiments conducted in this project were, firstly, to investigate the uptake and release of model compounds with different physico-chemical properties (i.e. solubility and logKoct/w) to and from two colloidal gel systems. Secondly, the permeation of model compounds across a model skin membrane (silicone membrane), and human epidermis was investigated. The first part of the project was to co-synthesise temperature-sensitive colloidal microgels particles based on a co-polymer of poly(N-isopropylacrylamide) (90%)-co-butyl acrylate (10%) (NIPAM/BA) (90/10)(w/w)%, in the presence of and in the absence of ibuprofen (IBU), methyl paraben (MP), and propyl paraben (PP), by a surfactant-free emulsion polymerisation (SFEP) in water. Physico-chemical properties of the microgels were determined using different techniques including photon correlation spectroscopy (PCS), transmission electron microscopy (TEM), nuclear magnetic resonance (NMR spectroscopy), and turbidimetric analysis (UV-vis). The uptake and release of the model compounds to and from colloidal microgel particles was controlled by the solubility and logKoct/w of the drugs. Their subsequent permeation across a model silicone membrane and human skin, were investigated over a range of temperatures (292 K – 313 K). The transport rate of IBU and, PP from poly(NIPAM) microgel is significantly reduced by two and one order of magnitude, respectively, compared with the transport rate of saturated solutions. A huge reduction in the flux indicates that the microgel retards permeation of the drug across both membranes, and hence the microgel can be considered as a permeation retarder. However, fluxes of MP from poly(NIPAM) microgel are equivalents to fluxes of saturated solutions of MP. There is a clear correlation between the solubility and logKoct/w value of the drugs and the flux value for the microgels, incorporating the drugs, across both types of membranes. In the second part of the work, a co-polymer of poly(NIPAM) (85%) co-butyl acrylate (10%) co-methacrylic acid (5%) (NIPAM/BA/MAA) (85/10/5) microgel was synthesised and investigated as a potential pH and temperature sensitive transdermal delivery device. Three compounds having different logKoct/w and solubilities were incorporated into the microgel, namely: salicylamide (SA), methyl paraben and propyl paraben.

Résumé :
Hydrogels are three dimensional networks of hydrophilic homopolymers or copolymers generally covalently or ionically crosslinked. They interact with aqueous media by swelling to some equilibrium value by retaining the aqueous media in their structures. This study concerns the investigation of the swelling and the controlled drug release behaviour of hydrogels synthesized via the photopolymerisation process. The study of hydrogels in this project was oriented towards their biomedical applications as controlled drug delivery devices. It is a known fact that the complete conversion of monomers to polymers may not be achieved in the polymerisation process thus there is always a certain component of unreacted toxic monomers still remained in the polymer matrix. These monomers have the tendency to leach out of the polymer matrices when the polymers are in contact with an aqueous medium thus rendering the hydrogel to be nonbiocompatable. The polymers synthesized in this work were washed thoroughly in milli-Q-water and then evaluated in vitro for any possible toxic effect on human keratinocyte (HaCaT)v cells using a 3-[4,5-dimethylthiazol-2-yl]-2,5-diaphenyl tetrazolium bromide (MTT) cell proliferation assay. The cytotoxicity results indicated that the hydrogels understudy sustained and allowed a positive growth of the HaCat cells in the duration of the cytotoxicity experiment, thus proving to be satisfactorily compatible.

Résumé :
Abstract Protein-based drug carriers are promising candidates for efficient drug delivery among the available potential colloidal carrier systems, due to their low cytotoxicity, abundance, renewability, diverse functional groups and interactions, and high drug loading capacity, etc. In this study, molecular dynamics (MD) simulations are performed to study the mechanisms of 11S molecule of soy protein as drug delivery vehicle to attach allyl isothiocyanate (AITC) and doxorubicin (DOX) drugs. The intermolecular interactions between protein and drugs are investigated; and the loading capacities of the protein molecules are calculated and compared with experiments. It is found that, for the AITC system, both nonpolar and polar residues of protein have the ability to adsorb AITCs; particularly, the polar residues serve as the primary active sites for the stable attachment of the drug molecules through the electrostatic (dipole-dipole) interactions. For the DOX system, however, the main driving force become the π-π stacking (the van der Waals interactions) among the aromatic rings of DOX and protein. In addition to pristine protein, different denaturation processes are found to be able to increase the exposure of active sites, therefore, enhance the loading efficiency of the protein carriers.

Résumé :
Target drug delivery is one of the core issues in modern medicine. Although both thermo-sensitive and magnetic drug vehicles have been developed for this purpose, reliable drug targeting is yet to achieve, because it’s hard to control local temperature in body for thermo-sensitive drugs, and it’s also difficult to control the colloidal sizes of magnetic vehicles to meet the requirements for both long-time circulation and magnetic responsibility. Here we present a new technology to solve these two problems. The drug (taxel) was combined with hyper-branched thermo-sensitive polymer and magnetic nanoparticles. Magnetic responsibility of the complex can be remotely controlled by applying an alternating magnetic field. The untreated complexes were stable in dispersion, while after exposing to the alternating magnetic filed for 5 minutes, the complexes were destabilized and deposited from dispersion quickly. Unlike the commonly used water bath, the technology present here can heat up the drug vehicles remotely from outside, which must have great potentials in the applications of magnetic or thermo-sensitive drug delivery.

Résumé :
Hydrogels based on collagen and xanthan have found various applications as drug delivery carriers. The main strategy is to combine the traditional perspective of using essential oils with polymeric hydrogels in order to develop a potential dressing that provides wound healing for first-degree burn injuries. In this regard, the present study is aimed to develop textile materials with potential for use in the treatment of first-degree burn injuries by approaching the hydrogels based on xanthan gum and collagen as polymeric matrix loaded with essential oils (cinnamon essential oil, tea tree essential oil), propolis (hydroglyceric extract or with content of colloidal silver) and drugs (chlorhexidine, ciprofloxacin). A total of six experimental variants of hydrogels were synthesized and then were applied by padding method on a plain weave textile structure from 100% cotton. The functionalized textile materials were characterized by morphological and antibacterial point of view. The textile materials treated materials with all synthesized hydrogels based on xanthan and collagen as polymeric matrices have antibacterial activity against S. aureus and E. coli test strains, the highest inhibition zone was provided by the samples loaded with ciprofloxacin (MUP3 and MUP4 code).

Résumé :
In transport phenomena involving colloidal nanoparticle (NP) suspensions in complex environments, the inter particle interactions play an important role especially when the sizes of the confining environments approaches the particle sizes. Specific examples of such systems are encountered in NP transport through nanochannels used in drug delivery and nanofluidic cooling[1–5]. In ionic colloidal suspensions like the ones encountered in the above applications, the NPs acquire characteristic surface charges which results in a surface potential and a double layer of co- and counter-ions from the solution. DLVO theory predicts the interaction energy resulting from the double layer to be [6]:(1)Wr=64πkBTRρ∞γ2κ2exp-κr where r is the separation between NP surfaces, and R is the radius of the NP, ρ∞ is the concentration of ions in the suspension, κ−1 is the Debye screening length (characteristic size of the double layer) and kB and T are the Boltzmann constant and the temperature. As κ−1 approaches the size range of the particles, the interactions amongst the particles may span several times the particle size and contributes to particle diffusion.

Résumé :
Though uncommon in most microfluidic systems due to the dominance of viscous and capillary stresses, it is possible to drive microscale fluid flows with considerable inertia using surface acoustic waves (SAWs), which are nanometer order amplitude electro-elastic waves that can be generated on a piezoelectric substrate. Due to the confinement of the acoustic energy to a thin localized region along the substrate surface and its subsequent leakage into the body of liquid with which the substrate comes into contact, SAWs are an extremely efficient mechanism for driving fast microfluidics. We demonstrate that it is possible to generate a variety of efficient microfluidic flows using the SAW. For example, the SAWs can be exploited to pump liquids in microchannels or to translate free droplets typically one or two orders of magnitude faster than conventional electroosmotic or electrowetting technology. In addition, it is possible to drive strong microcentrifugation for micromixing and bioparticle concentration or separation. In the latter, rich and complex colloidal pattern formation dynamics have also been observed. At large input powers, the SAW is a powerful means for the generation of jets and atomized aerosol droplets through rapid destabilization of the parent drop interface. In the former, slender liquid jets that persist up to centimeters in length can be generated without requiring nozzles or orifices. In the latter, a monodispersed distribution of 1–10 micron diameter aerosol droplets is obtained, which can be exploited for drug delivery and encapsulation, nanoparticle synthesis, and template-free polymer array patterning.

Résumé :
Review question / Objective: This systematic review aims to identify studies investigating the membrane vesicle-based drug de-livery systems (DDS) for HNSCC and define the potential of extracellular vesicles (EVs) in the treatment of this disease according to the current state of knowledge. Condition being studied: Head and neck squamous cell carcinoma (HNSCC), which is ranked the sixth most common malignancy worldwide, originates in the epithelium of the oral and nasal cavities, pharynx, and larynx. The treatment of HNSCC remains a challenge and requires the involvement of a multidisciplinary team. Currently available methods of treatment, such as surgery, radiotherapy, and chemotherapy, cause significant dysfunctions and toxicity, which highlights the necessity to explore new therapeutic options. One-third of patients treated with intended curative surgery and adjuvant therapy experience local or regional recurrence and/or distant metastasis.
