          Abstract

          Abstract Introduction: Deferoxamine mesylate increases hypoxia inducible factor-1 alpha transactivation by preventing iron-catalyzed reactive oxygen stress, so it can be used to improve diabetic ulcer healing. This study was undertaken to develop and study physicochemical properties of topical deferoxamine-loaded solid lipid nanoparticles. Method: Solid lipid nanoparticles were prepared using cold homogenization technique and full factorial design to evaluate the effect of surfactant type and amount of lipid. In-vitro characterization of formulations including particle size and distribution, thermal behavior using Differential Scanning Calorimetry, entrapment efficiency, and release profile were carried out. Results: The results showed an acceptable range of particle size (2.88-174 nm), a narrow size distribution, and an average of 60% for drug entrapment efficiency which is significant for a hydrophilic drug. The results from release study showed an initial burst release followed by a slow and prolonged manner. Differential Scanning Calorimetry results also confirmed the results obtained from loading and release evaluations. The best formulation which had a high level of drug loading and the lowest drug release rate contained compritol and oleic acid in the amount of 8% of the total formula, as well as tween 80 and lecithin as a mixture of surfactants. Conclusions: The study demonstrated deferoxamine could be loaded in solid lipid nanoparticles to deliver topically.

          Resumen Introducción: El mesilato de deferoxamina aumenta la transactivación alfa inducible por hipoxia del factor 1 al prevenir el estrés por oxígeno reactivo catalizado por hierro, por lo que puede usarse para mejorar la cicatrización de la úlcera diabética. Este estudio se llevó a cabo para desarrollar y estudiar las propiedades fisicoquímicas de nanopartículas lipídicas sólidas cargadas con deferoxamina tópica. Método: Se prepararon nanopartículas de lípidos sólidos utilizando la técnica de homogeneización en frío y un diseño factorial completo para evaluar el efecto del tipo de tensioactivo y la cantidad de lípidos. Se llevó a cabo la caracterización in vitro de las formulaciones, incluido el tamaño y la distribución de las partículas, el comportamiento térmico mediante calorimetría de barrido diferencial, la eficiencia de atrapamiento y el perfil de liberación. Resultados: Los resultados mostraron un rango aceptable de tamaño de partícula (2,88-174 nm), una distribución de tamaño estrecha y un promedio del 60% para la eficacia de atrapamiento del fármaco, lo que es significativo para un fármaco hidrófilo. Los resultados del estudio de liberación mostraron una liberación de ráfaga inicial seguida de una manera lenta y prolongada. Los resultados de la calorimetría diferencial de barrido también confirmaron los resultados obtenidos de las evaluaciones de carga y liberación. La mejor formulación que tenía un alto nivel de carga de fármaco y la menor tasa de liberación de fármaco contenía compritol y ácido oleico en una cantidad del 8% de la fórmula total, así como tween 80 y lecitina como una mezcla de tensioactivos. Conclusiones: El estudio demostró que el mesilato de deferoxamina podría cargarse en nanopartículas de lípidos sólidos para administrar por vía tópica.

          Solid Lipid Nanoparticles: A Modern Formulation Approach in Drug Delivery System

          Solid lipid nanoparticles are at the forefront of the rapidly developing field of nanotechnology with several potential applications in drug delivery, clinical medicine and research, as well as in other varied sciences. Due to their unique size-dependent properties, lipid nanoparticles offer the possibility to develop new therapeutics. The ability to incorporate drugs into nanocarriers offers a new prototype in drug delivery that could be used for secondary and tertiary levels of drug targeting. Hence, solid lipid nanoparticles hold great promise for reaching the goal of controlled and site specific drug delivery and hence have attracted wide attention of researchers. This review presents a broad treatment of solid lipid nanoparticles discussing their advantages, limitations and their possible remedies. The different types of nanocarriers which were based on solid lipid like solid lipid nanoparticles, nanostructured lipid carriers, lipid drug conjugates are discussed with their structural differences. Different production methods which are suitable for large scale production and applications of solid lipid nanoparticles are described. Appropriate analytical techniques for characterization of solid lipid nanoparticles like photon correlation spectroscopy, scanning electron microscopy, differential scanning calorimetry are highlighted. Aspects of solid lipid nanoparticles route of administration and their biodistribution are also incorporated. If appropriately investigated, solid lipid nanoparticles may open new vistas in therapy of complex diseases.

            Solid lipid nanoparticles for parenteral drug delivery.

            This review describes the use of nanoparticles based on solid lipids for the parenteral application of drugs. Firstly, different types of nanoparticles based on solid lipids such as "solid lipid nanoparticles" (SLN), "nanostructured lipid carriers" (NLC) and "lipid drug conjugate" (LDC) nanoparticles are introduced and structural differences are pointed out. Different production methods including the suitability for large scale production are described. Stability issues and drug incorporation mechanisms into the particles are discussed. In the second part, the biological activity of parenterally applied SLN and biopharmaceutical aspects such as pharmacokinetic profiles as well as toxicity aspects are reviewed.
